Job Title: Defence Account Director Location: London; full in-office working as default Start date: ASAP Reports to: CCO Compensation: Salary and Equity options available for discussion Clearance: Must be eligible to hold UK Security Vetting Clearance SC or above (no prior clearance required) Application deadline: 01/11/26 at 23:59 UK time ___________________________________________________________________________ Help make sovereign AI operational for UK Defence Cosine is a UK AI lab building models, applications and infrastructure for mission-critical organisations. We build coding agents, specialised Lumen models, AI-native security products and the infrastructure required to deploy advanced AI in demanding environments. We are also training Lumen Sovereign, the first frontier large language model trained in the UK, with the support of the UK Government. Defence is a strategic priority for Cosine. AI will change how Defence operates, from software engineering and intelligence analysis to cyber security, command and control, logistics and frontline operations. The challenge is turning advanced AI into capability that is trusted, secure, sovereign and useful in the real world. We are looking for a Defence Account Director to help build that business. This is not a traditional defence sales role. You will understand where Cosine can make a genuine operational difference, identify the right customers and programmes, shape credible opportunities and help turn early conversations into funded pilots, programmes and long-term customer relationships. You will work closely with Cosine's Defence Lead, technical teams and senior leadership. You will build relationships across the MOD, the Armed Forces, wider Government and the UK defence industry, while helping define Cosine's position in the emerging sovereign AI market. ___________________________________________________________________________ What you'll do Build and own a prioritised Defence account and opportunity strategy. Develop trusted relationships with senior stakeholders across the MOD, Front Line Commands, wider Government and defence industry. Identify operational problems, programmes and capability gaps where Cosine can make a material difference. Translate customer needs into clearly defined use cases, propositions, pilots and programmes. Navigate Defence stakeholders, budgets, acquisition routes, procurement processes and decision-making structures. Lead opportunities from initial conversation through demonstration, technical evaluation, commercial agreement and delivery. Work with Cosine's technical teams to create credible customer propositions without overpromising. Develop relationships with primes, strategic partners and specialist technology companies where this creates a stronger route to market. Maintain disciplined account planning, pipeline management, qualification and forecasting. Bring structured customer and market insight back to Product, Engineering, ML and senior leadership. ___________________________________________________________________________ What we're looking for You may have served in the UK Armed Forces or worked closely with Defence in engineering, capability development, acquisition, procurement, digital transformation or technology adoption. You may subsequently have worked in consulting, technology, industry or an advisory role. What matters is that you understand how Defence works and can turn a customer need into commercial momentum. You should have: Meaningful experience of the UK Defence ecosystem. Strong existing relationships across Defence, Government or industry, and the ability to build new ones. Experience introducing, acquiring or adopting complex technology. The ability to structure ambiguous problems and turn them into actionable opportunities. Strong commercial judgement and comfort being accountable for pipeline, opportunities and revenue. The confidence to engage with operators, engineers, procurement teams, senior civil servants, military leaders and industry executives. Genuine technical curiosity and the ability to learn enough about AI to have credible conversations with technical teams and customers. The resilience to work through long Defence sales cycles while maintaining urgency and focus. The independence and judgement to operate in a scale-up where the playbook is still being written. You do not need to be an AI expert when you join. You do need to be intellectually curious, technically literate and able to communicate clearly without hiding behind jargon. ___________________________________________________________________________ What success looks like Success ultimately means winning business and building enduring customer relationships. We aim to onboard at least 10 new client logos within the Defence account over the next 12 months and increase revenues by at least 300%. We expect that growth to come through credibility, judgement, customer insight and persistence rather than transactional selling. In your first few months, you will: Build a clear view of Cosine's Defence proposition, capabilities and priorities. Establish a focused account and stakeholder map. Develop relationships with priority customers and partners. Identify and qualify the most promising opportunities. Create a disciplined approach to account planning, pipeline and forecasting. Over time, you will help convert those opportunities into funded demonstrations, pilots and programmes, while shaping how Cosine is understood and adopted across UK Defence. ___________________________________________________________________________ Why this role matters Defence does not need more AI demonstrations that remain disconnected from operations. It needs technology that can work across real missions, real systems, real security constraints and real acquisition processes. You will help make that happen. This is an opportunity to build Cosine's Defence business from the ground up, with direct access to leadership and technical teams and genuine influence over our product, market strategy and customer relationships. If you understand Defence from the inside, have strong customer instincts and want to help make sovereign AI operational, this is an opportunity to have significant impact. ___________________________________________________________________________ Why join Cosine Build a strategically important business from the ground up. Work at the intersection of frontier AI, Defence and national capability. Sell a genuinely differentiated product into mission-critical environments. Influence product direction and go-to-market strategy. Work closely with a small, technically deep and ambitious team. Receive meaningful early equity with genuine upside. ___________________________________________________________________________ Compensation, Benefits & Ways of Working We're an in-office team, five days a week, by design. We believe the work we're doing benefits from being together, collaborating closely, and building shared context. What you can expect: Competitive salary , benchmarked to the market Equity / share options , so you share in the upside you help create 30 days' holiday + bank holidays Work hard in the office, collaborate closely, and switch off properly Dog-friendly office — bring your dog to work Weekly team breakfast & lunch Monthly socials Pension High-quality equipment to do your best work We care about focus, sustainability, and doing great work — not performative overwork.

The Opportunity Lumai's optical engine only works if the electronics around it hold up. Our boards carry large FPGAs and custom ASICs, multi-gigabit links and fine-pitch packages, and they have to be laid out to tolerances that leave no room for guesswork. This role takes the designs coming out of our hardware and SI/PI teams and turns them into manufacturable, high-layer-count boards. The Role You will own board layout from schematic handoff to fabrication release. That covers stackups and HDI structures, controlled-impedance routing, differential pairs, length and phase matching, BGA breakout for large fine-pitch devices, and the full manufacturing package: Gerber/ODB++, drill files, assembly drawings and fabrication notes. You will also own the footprint and symbol libraries, the design rules and the CAD standards the rest of the team works to. What is genuinely hard about it is that the constraints are real and they conflict. Signal integrity, power integrity, thermal and mechanical requirements all land on the same square centimetres, and the fabricator's process limits decide what is actually buildable. You will be the person who turns simulation output into layout rules and who can defend a stackup to a fabricator. By month six, you will have taken at least one board through to fabrication release, set the libraries and design rules the team works from, and be the first point of contact for our fabricators and assembly houses. What You'll Do Lay out dense, high-layer-count PCBs from schematic through to fabrication release, using constraint-driven flows. Implement controlled-impedance routing, differential pair and length/phase matching, and HDI structures including microvias, via-in-pad and back-drilling. Plan BGA breakout and component placement for large FPGAs, custom ASICs and fine-pitch packages, balancing SI, PI, thermal and mechanical requirements. Translate SI/PI and hardware constraints into layout rules, and iterate quickly with engineers on simulation feedback. Run DFM, DFA and DFT reviews, and act as the main technical contact with PCB fabricators and assembly houses. Generate complete manufacturing outputs (Gerber/ODB++, drill files, assembly drawings, fabrication notes) and manage design revisions. Own and maintain the footprint and symbol libraries, CAD standards and design templates, compliant with IPC standards. What We're Looking For Must-have Extensive professional experience laying out complex, high-speed, high-layer-count boards, with a portfolio of designs that went into production. Expert proficiency in Cadence Allegro, including Constraint Manager. Equivalent Altium experience will also be considered. Hands-on experience with HDI technologies: microvias, via-in-pad, stacked and staggered vias, and back-drilling. Proven BGA breakout and placement for large, fine-pitch devices such as FPGAs and ASICs. Thorough working knowledge of IPC standards (IPC-2221, IPC-7351, IPC-6012) and of DFM/DFA/DFT principles. Strong preference for Boards carrying 56G+ SerDes, PCIe Gen5/6 or DDR5 interfaces. Working closely with SI/PI simulation engineers. Rigid-flex, RF or mixed-signal layouts. ECAD/MCAD collaboration on thermal and mechanical integration. Experience setting up CAD standards, libraries and design templates in a growing team. About Lumai Lumai is the optical compute company building the next generation of AI infrastructure. Spun out of optics research at the University of Oxford in 2021, we compute with light instead of electrons. Our 3D optical technology carries out the matrix multiplications at the heart of AI inside beams of light travelling through free space, which lets it go beyond the limits of both silicon GPUs and integrated photonics. In April 2026 we launched Iris Nova, the world's first optical computing system to run billion-parameter large language models in real time, using up to 90% less energy than conventional GPU-based systems. Iris Nova, the first server in the family, is now available for evaluation by hyperscalers, neoclouds, enterprises and research institutions. Aura and Tetra will follow. Our work won the Falling Walls Award for Science Breakthrough of the Year 2025 and 'Best Overall Technology' at the OCP Future Technologies Symposium. We are headquartered in Oxford. Why Lumai You'll work on a new kind of computer. Optical computing for AI has been promised for decades. We have a working system running real models, and the hard part left is taking it to volume. Your work ships. We are moving from first product to volume production, so what you build this year goes into the servers our customers run. You'll work across disciplines. Optical engineers, machine learning researchers, and hardware and software engineers solve problems together. You will learn things that don't appear on your job description. The work matters beyond Lumai. AI's appetite for energy is one of the defining constraints of the next decade. Our mission is sustainable intelligence at global scale: AI that is faster, cheaper to run and far less power-hungry. You'll join early. You'll have a real say in how we build the product, the team and the way we work. Equal Opportunity Lumai is an equal opportunity employer. We make hiring decisions based on skills, experience and potential, and we welcome applications from people of all backgrounds. If you need an adjustment at any stage of the hiring process, let us know and we will do our best to support you. Find more English Speaking Jobs in United Kingdom on Arbeitnow

As an Implementation Engineer for Plaid Europe, you'll own customer integrations from the moment a contract is signed to the moment they're live in production and growing. You'll write the integration plan, run the kickoff, debug alongside the customer's engineers, validate their sandbox implementation, and see them through go-live, keeping their Account Manager up to date with notes that make the relationship easy to continue. You'll do the same for existing customers adding a new product, use case, or market. You'll also build the resources that make the next integration faster – the checklists, the common pitfalls, and the answers to the questions every customer asks – because this team is small and its leverage comes from what gets written down. Responsibilities Own a portfolio of customer integrations from signature to production launch, including plans, milestones, and exit criteria. Run scheduled implementation support for standard integrations, as well as one-off debugging engagements for customers who need a targeted fix. Lead technical onboarding for existing customers adopting a new Plaid product, use case, or market.

About Zelara Most CRM marketing still blasts generic messages at scale and calls it "personalization." Our founders experienced this firsthand in senior roles at HelloFresh, Salesforce, Uber, and others. Backed by top-tier VCs, they decided to build a better way. Zelara is an agentic lifecycle marketing platform that improves with every interaction. It works with the CRM infrastructure our customers already use, replacing static journeys and manual segmentation with a system that creates content, makes individual-level decisions, and learns from every outcome. With bunq, Europe's second-largest neobank, we delivered +7.4% activation and +66% reactivation uplift, measured against a control group. We raised a €3M pre-seed and are generating revenue with paying enterprise customers. We are growing our Solutions Architecture team to make the path from integration to measurable value repeatable across more customers. The Role This is a deeply technical customer role centered on post-sales value realization, with involvement in pre-sales discovery. It is not reactive customer success, nor a pre-sales role that hands off at signature. You own technical value realization for a portfolio of customers, from discovery and onboarding through live experiments, measured results, and scaled adoption. You and the commercial lead run each account as a pair. They own pricing, contracts, expansion, and renewal. You own the technical plan and the evidence behind those decisions: before signature you lead technical discovery alongside them, after signature you are the customer's named technical lead for solution design, data mapping, the experiment plan, and go-live. There is no separate customer success manager; the two of you hold the whole relationship. Product, Engineering, and Science own the platform, the integrations, and the measurement standards. You turn their work into a working customer solution and bring them in when a requirement crosses those lines. Our customers are mid-market and enterprise B2C companies across Europe: fintech, e-commerce, travel, and employee benefits. What You Will Do Lead technical discovery before signature: how the customer makes money, which metric moves it, and what the pilot can credibly promise Own onboarding: align stakeholders, define the data mapping and acceptance criteria, and take the customer live on its existing CRM stack Design and pre-register each experiment to Zelara's scientific standards, because a success bar set after seeing the data is not a result Own the customer-facing readout: reconcile our analysis with the customer's data, and say clearly when the evidence is not decision-ready Enable the customer's team to run campaigns independently Partner with the commercial lead on annual contracts, expansion, and renewal Drive the product loop: turn recurring customer needs into product opportunities and research questions, backed by evidence from live accounts, and use agents to build the scripts and prototypes that unblock an account in the meantime Your First 90 Days 30 Days: Learn the platform and the portfolio, join the active accounts, and take over your first technical customer relationship. 60 Days: Lead one onboarding independently, with the integration, experiment design, and measurement plan agreed before launch. 90 Days: Own a small portfolio and deliver your first evidence-backed results readout. Who You Are You have led deployments, implementations, or technical accounts for mid-market or enterprise customers at a B2B SaaS company, and your work has influenced adoption, renewal, or expansion. You judge a customer's business before you design for it: which metric their leadership is held to, and what matters that nobody has said out loud. You have led real customer integrations and know that a successful import is not the same as usable data. You turn a business question into an analysis plan and understand experiments: control groups, effect sizes, statistical power, and why the design is frozen before it runs. You know the lifecycle marketing stack (Braze, Bird, Iterable, Klaviyo, Customer.io , Emarsys, HubSpot) and how a CRM team works inside it. You are credible with a Head of CRM and their data engineer in the same hour. You say the uncomfortable thing early, and a commitment with a date on it is a commitment. You are AI-native. A software engineering background is not required, but building with agents is: the script that reshapes a customer's export, the prototype that shows a CRM team what we mean. You are fluent in English. German is a strong advantage given our current market focus. Bonus You have run lifecycle or CRM programs in-house, so you know what we ask a customer's team to change. You have experience with experimentation platforms, bandits, or applied ML in production. You have converted pilots or POCs into multi-year contracts and can say what moved the decision. How We Work We are an AI-first team. We adopt what makes us faster and drop what does not, and we value evidence, speed, and clear ownership over process theater. What We Offer Work alongside founders who have built and sold an AI-driven SaaS business and led large-scale B2C operations from the customer's side of the table. A senior individual-contributor role in a small Solutions Architecture team, with real influence on how we deliver. Autonomy over onboarding, pilots, and technical value realization, and a tight working relationship with Product, Science, and Engineering. Direct access to real customers and real production data. Based in Berlin, with regular travel to European customers. A competitive salary and a meaningful equity stake. Your choice of a Deutschlandticket or bike subscription, plus a gym membership. Our Compass We are guided by four core values: Seek Truth: We ground decisions in evidence. When the facts change, we change our mind. Act with Integrity: We build trust through transparency, reliability, and ownership. Put Customers First: We succeed only when they succeed. Find more English Speaking Jobs in Germany on Arbeitnow

Daarnaast is het van toegevoegde waarde als je ervaring hebt met: consultancy binnen complexe enterprise-omgevingen; solution architecture of technical leadership; Kubernetes en Terraform; Spark, Kafka en/of Airflow; TensorFlow en/of PyTorch; generative AI en Large Language Models (LLM's); deep learning, causal inference of reinforcement learning; Scala, Kotlin en/of SQL; open-sourceprojecten, meetups, conferenties of andere vormen van kennisdeling. We verwachten niet dat je met iedere technologie uit onze stack hebt gewerkt. De senioriteit van je ervaring, het daadwerkelijk in productie brengen van machine-learningoplossingen, je vermogen om klanten inhoudelijk te adviseren en je beheersing van het Nederlands zijn voor deze rol wel essentieel. Je bent technisch sterk, maar kijkt verder dan alleen de technologie. Je kunt complexe situaties doorgronden, alternatieven afwegen en uitleggen waarom een bepaalde oplossing wel of niet verstandig is. Je voelt je comfortabel in gesprekken met engineers, architecten en business stakeholders. Tegelijkertijd blijf je graag zelf bouwen. BigData Republic zoekt geen consultant die alleen vanaf de zijlijn adviseert: je combineert senior technisch advies met hands-on Machine Learning Engineering.
