Description du poste

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.
