We are focused on delivering deployable, high-performance capability — not future promises. In a time of rising threats, our work strengthens the technological edge of NATO Allies and their Partners. About the team You will join our hardware engineering team, working closely with engineers across propulsion, power systems, testing, and aircraft development to turn measured data into better-performing unmanned systems. Your mission Your mission is to work hands-on with the parts of the aircraft that turn stored energy into flight: the motors, the batteries, and the propulsion and power components that decide how far, how fast, and how long our platforms fly. You support the hardware team from bench characterisation through data analysis in MATLAB and Python. You aren't just swapping components on a bench; you are helping generate the measured evidence that decides what actually flies — and learning how unmanned hardware is designed, tested, and pushed to its limits. Responsibilities Support characterisation and bench testing of motors, propellers, batteries, and power components for our UAS platforms. Help set up test rigs and instrumentation, and capture clean, repeatable measurement data. Assist with component selection and trade-offs by turning test data into clear comparisons. Reduce and analyse test data in MATLAB and Python — efficiency, thrust, endurance, thermal and discharge behaviour. Visualise results so the engineering team can make decisions from them quickly. Keep test setups, measurements, and findings documented and traceable. Qualifications Currently enrolled in a Bachelor's or Master's in Electrical, Mechanical, Aerospace, or a comparable engineering field. Working knowledge of MATLAB and Python for data analysis. Interest in and some exposure to UAS, electric propulsion (motors / ESCs), or battery / power systems. Must be a citizen of a NATO member state (due to export control and security regulations). Practical, hands-on mindset — comfortable at the bench and with a multimeter as much as in a script. Good written and verbal communication skills in English; German is a plus. Hands-on: You like building, measuring, and finding out what really happens. Rigorous: You trust clean measurements over assumptions. Curious: You want to understand why a component behaves the way it does. Nice to have Experience with test benches, DAQ, or measurement instrumentation. Familiarity with battery testing, thermal behaviour, or motor/propeller characterisation. Personal projects with drones, RC aircraft, batteries, or robotics. Equal Opportunity: At Stark Defence, we are committed to building a diverse, inclusive, and high-performing team. We operate in an industry where women, as well as other minority groups, are systematically under-represented. We actively encourage applications from candidates of all backgrounds and identities. If you are excited about this role, we encourage you to apply even if you don't meet all the listed qualifications—ability and impact cannot be summarised in a few bullet points. We value unique perspectives, adaptability, and a drive to solve high-stakes challenges. Security Clearance: Due to the nature of our work in the defence sector, candidates must be eligible to obtain and maintain the appropriate security clearance required for this position. Details will be provided during the recruitment process. Find more English Speaking Jobs in Germany on Arbeitnow
