Senior Battery Electrical Engineer

Senior Battery Electrical Engineer | NewSpace Startup

Ivry-sur-Seine, France | Permanent | On-site

Want to build battery technology that will fly into space?

We’re working with a fast-growing NewSpace startup developing next-generation power systems for commercial LEO satellites. You’ll join a small, highly technical team where you’ll have genuine ownership from cell selection → BMS → testing → flight-ready hardware.

What You’ll Do

• Design battery pack electronics and high-current PCBs
• Develop BMS hardware and functions: SoC/SoH, balancing & protection
• Lead cell, battery and BMS testing
• Select and qualify cells for the LEO environment
• Work hands-on across design, lab testing and validation

We’re Looking For

• MSc/equivalent in Electrical Engineering or Electronics
• 5+ years in battery systems or power electronics
• Strong Li-ion, BMS and high-current electronics experience
• Hands-on laboratory/testing experience
• Professional-level English
• Low-ego, curious and highly practical mindset

Space/aerospace/automotive experience is a plus, not essential.

Why join? Small team. Big ambition. Real ownership. Your work will fly.

Candidates already based in France/EU are particularly encouraged to apply.
