Senior DevOps Engineer

Senior DevOps Engineer (Contract) We’re looking for a hands-on Senior DevOps Engineer to own the implementation, rollout, and ongoing operation of our delivery platform, and to enable CI/CD adoption across multiple scrum teams. This is a builder-operator role: you’ll spend your time standing up platform capabilities, keeping production healthy, and removing delivery friction for engineering teams - not just advising on it. You combine deep technical execution with the seniority to set standards, lead through incidents, and mentor others. What You’ll Do Implement and roll out core platform capabilities (Kubernetes-based runtime, build/deploy tooling, observability) across teams and environments. Build reusable templates, Helm charts, pipeline definitions, and IaC modules that teams can adopt with minimal friction. Onboard scrum teams onto the platform - migrating workloads, standardizing configuration, and documenting self-service paths. Drive consistent adoption of platform standards while accommodating legitimate team-specific needs. Own day-to-day health, configuration, and lifecycle of the platform and its supporting infrastructure. Plan and execute infrastructure and platform upgrades (Kubernetes versions, node pools, runtimes, agents, tooling) with minimal disruption. Manage platform configuration changes through controlled, auditable processes. Provide responsive support to engineering teams using the platform, acting as the escalation point for platform-related issues. SSL/TLS certificate renewals and rotation, secret/credential rotation, patching, and capacity adjustments performed on a recurring, reliable cadence. Plan and carry out infrastructure upgrades and maintenance windows, including rollback planning and stakeholder communication. Maintain and tune platform configuration for scalability, resiliency, performance, and cost efficiency. Lead incident response for production issues - triage, mitigation, coordination, and resolution - and run blameless post-incident reviews with concrete follow-up actions. Improve observability, monitoring, and alerting so issues are caught proactively rather than reported by users. Design, implement, and maintain automated CI/CD pipelines covering build, test, release, and deployment across Windows and Linux workloads. Enable scrum teams to own their pipelines through shared templates, reusable steps, and clear documentation. Promote sound source control, branching, and release management practices. Embed security and compliance controls directly into pipelines (DevSecOps) - scanning, policy gates, and secrets handling. Continuously reduce lead time, deployment friction, and manual steps in the delivery lifecycle. Provide Level-3 support for complex production and platform incidents. Identify and act on opportunities to improve system stability, operational maturity, and self-service. Optimize platforms and processes based on measurable outcomes (deployment frequency, change failure rate, MTTR, cost). Maintain strong, current technical documentation and runbooks. Partner with Application Architects and engineering teams to align platform and DevOps solutions with product needs. Mentor and coach engineers on DevOps practices, pipeline ownership, and operational discipline. Promote a culture of automation, ownership, and continuous improvement. Research emerging tools and practices that improve the delivery lifecycle, and introduce cost-effective solutions that increase speed, quality, and reliability. Active AI practitioner- leverages AI-assisted tooling (Claude, Cursor, Copilot) to accelerate engineering and operational work. What You Bring At least 5 years of hands-on DevOps, platform, or infrastructure engineering experience within distributed systems or large enterprises. Bachelor’s degree in Computer Science or related discipline, or equivalent work experience. Kubernetes administration and containerization (Docker, Helm), including platform upgrades and lifecycle management. CI/CD orchestration across Windows and Linux environments (TeamCity, Octopus). Infrastructure automation and scripting (Terraform, Ansible, PowerShell, Bash). Cloud infrastructure administration (Azure / AWS). Log collection and dashboarding (ELK, New Relic). Practical experience with production operations: SSL/TLS certificate management, networking, load balancing, caching, high availability, and disaster recovery. Demonstrated experience operating production systems and leading incident response. Nice to Have Experience rolling out internal developer platforms or self-service tooling across multiple teams. Familiarity with policy-as-code, secrets management, and DevSecOps tooling. Experience defining and tracking delivery/reliability metrics (DORA or similar).
