Job summary

Gama, a NewSpace startup, seeks a Hardware Test Engineer to drive test campaigns for solar arrays, power electronics and batteries. You will design benches, write procedures and ensure data reliability for scale‑up to production.

You will work with mechanical, electrical and manufacturing engineers to shape hardware testing, maintain calibration and uphold safety in a fast‑paced, international environment.

Qualifications

• Engineering degree or Master’s in electrical, mechanical, aerospace or physics engineering.
• 3+ years hands‑on hardware test lab experience, space/aerospace/energy or similar.
• Experience running environmental or electrical test campaigns, from plan to report.
• Strong instrumentation and measurement skills (sensors, data acquisition, power supplies).
• Programming skills for test automation and data analysis.
• Rigorous, safety‑minded approach with documentation and traceability.
• Proactive ownership and ability to work with multiple teams.
• Professional level English; French is a plus.

Responsibilities

• Set up, operate and maintain lab test equipment (TVAC, chambers, solar simulators, power supplies, loads).
• Define end‑of‑line and acceptance testing for high‑volume production.
• Design and build test benches and fixtures for cells, arrays, power electronics and batteries.
• Write test plans, procedures and reports; run development, qualification and acceptance campaigns.
• Develop and maintain test automation and data acquisition software (e.g., Python, LabVIEW).
• Own equipment calibration and preventive maintenance; apply lab safety rules.
• Contribute to spec of new test equipment; liaise with suppliers and facilities.
• Support anomaly investigations and root-cause analyses.

Job description

Rockets have not gotten wider. Satellites need far more power than they used to. The only way through is structures that pack into a fairing and unfold into something massive on orbit.

Gama is building that: ultra-light deployable solar arrays, from 3 kW to over 100 kW, in a factory sized for 100 MW a year by 2030. Inventing the hardware is one half of the problem. The other half is proving it works - on the ground, before it ever reaches orbit, and at a pace that keeps up with the factory.

As Hardware Test Engineer, reporting to the Head of Lab & Production, you will prepare and run the test campaigns on Gama’s solar arrays, power electronics and batteries, from first prototypes through qualification to production acceptance. You will design the test benches, write and execute the procedures, and make sure every test produces data the design teams can trust. You will work daily with our mechanical, electrical and manufacturing engineers, and help shape how Gama tests hardware as it scales to volume production.

Your mission will be to:

• Set up, operate and maintain the lab’s test equipment: environmental chambers, thermal vacuum (TVAC), vibration, solar simulators, power supplies, electronic loads and data acquisition systems.
• Define end-of-line and acceptance testing for high-volume production, an unusual scale for the space industry, using best-in-class production test assets to deliver the reliability our products are built on.
• Design and build test benches and fixtures for solar cells, solar array coupons and panels, power electronics and battery modules.
• Write test plans, procedures and reports, and run development, qualification and acceptance test campaigns.
• Develop and maintain test automation and data acquisition software (e.g., Python, LabVIEW), and turn raw data into clear, actionable results for the design teams.
• Own equipment calibration and preventive maintenance, and apply lab safety rules (high voltage, batteries, pressurized and hazardous environments).
• Contribute to the specification of new test equipment, and work with equipment suppliers and external test facilities.
• Support anomaly investigations and root‑cause analyses, and feed results back into design and manufacturing.

Profile required

• Engineering degree or Master’s in electrical, mechanical, aerospace or physics engineering.
• 3+ years of hands‑on experience in a hardware test lab, in space, aerospace, automotive, energy or a similarly demanding field.
• Experience running environmental or electrical test campaigns, from test plan to final report.
• Solid skills in instrumentation and measurement: sensors, data acquisition, power supplies and loads.
• Programming skills for test automation and data analysis.
• A rigorous, safety‑minded approach, with care for documentation and traceability.
• A proactive attitude, full ownership of your test campaigns, and the interpersonal skills to work with many teams at once.
• Professional level English; French is a plus.

Nice to have

• Experience with space qualification testing: thermal vacuum, thermal cycling, vibration and shock.
• Knowledge of photovoltaic testing (I‑V curves, solar simulators, electroluminescence) or battery testing (cycling, abuse and safety tests).
• Familiarity with space testing standards.
• Experience setting up a lab from scratch in a startup or scale‑up.

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.
• Relocation support for international hires, where needed.
