Thermal Engineer
About the Company:
Space Cargo Unlimited is a European pioneer in in-space manufacturing and research. Headquartered in Luxembourg, they're building REV1 — a pressurized, returnable space platform designed to become the world's first commercial space factory. With missions already flown on SpaceX Dragon, Blue Origin, and the ISS, and 7 upcoming multi-week missions starting Q4 2025/2026, SCU is one of Europe's most exciting New Space companies right now. They recently brought on former ESA Director General Jan Wörner as Chief Strategy Officer — a serious signal of ambition.
The Role:
SCU is looking for a Thermal Engineer to own the thermal control systems of both their BentoBox payload infrastructure and the REV1 spacecraft. You'll be designing and analyzing thermal management solutions that keep hardware alive through launch stress, the vacuum of LEO, and reentry — one of the harshest engineering environments that exists.
What You'll Work On:
Thermal design and analysis for the BentoBox pressurized platform and REV1 subsystems
Heat transfer solutions for active payloads operating in microgravity
Ensuring component reliability across extreme temperature cycling (space vacuum doubles as a thermal stress chamber)
Collaboration with a multidisciplinary team across Luxembourg, France, and Germany
Ideal Profile:
Strong background in thermal analysis and heat transfer principles
Experience with space environment challenges (LEO thermal cycling, vacuum, radiation)
Aerospace industry background preferred
Comfortable working in a fast-moving, mission-driven startup environment
Why This Role is Interesting:
They just signed a partnership with Dassault Aviation to integrate BentoBox into their VORTEX reusable spaceplane. This isn't a "study phase" company — they're flying hardware. A Thermal Engineer joining now will have direct impact on real missions launching within months.
