Job description
To pursue our ambitious vision, we are looking for a Senior Power Test Engineer. In this role, you will build the test infrastructure — hardware, software, and methods — that qualifies our batteries and power electronics for flight.
Your mission will be to:
- Design and build the test benches for battery cells, packs, BMS subsystems, and power converters: fixtures, instrumentation, power and safety infrastructure.
- Automate the test benches: test sequencing, instrument control, data acquisition, and data processing pipelines.
- Implement mission-representative test scenarios on the benches: orbital charge/discharge profiles, eclipse cycling, and thermal environments, based on use cases provided by the design team — no prior space background needed.
- Define and run qualification campaigns to get our hardware ready for flight: environmental testing (thermal, thermal-vacuum, vibration) and functional verification toward flight acceptance.
- Operate and develop the in-house cell testing laboratory: cyclers, thermal chambers, safety infrastructure, lab processes, and interaction with equipment suppliers.
Profile required
- Professional engineering education (MSc or equivalent) in electrical engineering / electronics, with 5+ years of hands-on test engineering experience.
- Experience testing batteries or power electronics: cyclers, electronic loads, power supplies, power analyzers, thermal chambers.
- Test automation and scripting skills (Python or similar): instrument control, data acquisition, data analysis.
- Solid electronics fundamentals: measurement techniques, sensing, wiring, grounding, and safe practices around high currents and voltages.
- Autonomy in the lab: oscilloscopes, differential/isolated probes, power analyzers, electronic loads.
- Strong analytical skills, a proactive attitude, excellent interpersonal skills and unbounded curiosity.
- You enjoy owning your scope end-to-end.
- Professional level English — further languages welcome.
Nice to have:
- Experience in space, aerospace, automotive, high volume consumer electronics, or other constrained industries.
- Understanding of Li-ion cell behavior: aging mechanisms, safety, and characterization methods (ACIR/DCIR, EIS, RPT-based protocols).
- Experience with environmental testing: thermal-vacuum, vibration, shock.
- Experience with power electronics testing.
- Experience with databases and data pipelines.
- Familiarity with LabVIEW/TestStand or equivalent test frameworks.
Company description
Gama is a NewSpace startup based in Ivry-sur-Seine, near Paris. We are developing a next-generation power system for commercial LEO satellites — from solar array power conversion to battery energy storage. We design, build, and test our hardware in-house, and we move fast: our engineers see their designs go from schematic to flight hardware.
We are a small team where ownership matters: you own your subsystem end-to-end, from first calculations to test results. We work hands-on, we help each other without ego, and we treat mistakes as data — finding out why something failed is how we get better.
We offer:
- Your work will fly. Contribute directly to the future of space exploration and Sustainable Space.
- Access to cutting-edge facilities and development opportunities in the heart of the European space industry.
- A steep personal development path, working alongside world class aerospace engineers.
- Equity package and competitive compensation.
- A highly talented, dynamic and international team.
You do not need to meet every requirement to apply. If this role excites you and you meet many, but not all, of the criteria, we would be glad to hear from you. We value potential and support growth into the role.
