Want to work on spacecraft that are actually being built and flown?

We're partnering with a fast-growing Australian space and defence technology start-up developing next-generation spacecraft and autonomous systems designed to protect critical infrastructure in orbit.

They're building spacecraft capable of rendezvous, proximity operations and rapid response in space, alongside software that uses AI and space-domain data to help operators monitor, coordinate and protect assets in orbit.

They're now looking for a Spacecraft Thermal Engineer to own thermal analysis and design across the vehicle, working closely with electronics, avionics and wider spacecraft engineering teams.

What we're looking for:

- 2+ years' thermal engineering experience
- Hands-on experience building and running thermal models
- Experience with Thermal Desktop, ESATAN, Systema/Thermica, NX Space Systems Thermal or equivalent
- Robust understanding of spacecraft thermal environments
- Experience working with electronics / avionics from a thermal perspective
