Senior Mechanical Design Engineer

Senior Mechanical Engineer 📍 Greater Paris | 💰 €70,000–€90,000 | Relocation support available—Most engineers get hired to repeat what they already know how to do. This role is the opposite.A NewSpace startup near Paris is building deployable hardware for spacecraft from a blank sheet. Everything is designed, built, and tested in-house, and every part has to work at real production volume, not just as a one-off.We're looking for a Senior Mechanical Engineer to join them and own real hardware end to end. The technology is spacecraft. The mindset they're hiring for isn't specific to it.What matters more than a space background:→ You've taken hardware from blank page to working reality more than once, in any industry→ You reach for the textbook when you hit something unfamiliar, and actually work through it→ You treat requirements as a starting point to question, not a fixed brief→ You're curious before you're credentialedA good fit looks like:→ Strong CAD (CATIA, Siemens NX, SolidWorks) and FEA, with hand calculations to back it up→ Roughly 5+ years' experience, though what you've built matters more than the number→ A track record with hardware built to survive harsh conditions→ Genuinely driven, genuinely autonomous, comfortable without a rulebookIf most of your career has been executing someone else's finished spec, this probably isn't for you.Space experience is a plus. It is not a requirement.In return: equity and competitive pay, English as the working language, French lessons to help you settle in, and a small team where ownership is real, not a buzzword.If you're the kind of engineer who takes something apart to understand it, get in touch.#NewSpace #MechanicalEngineering #FirstPrinciples #DeployableStructures
