As a Thermal Space Engineer Lead, you will join our team in Stevenage to support our activities within the Space sector.
You will take ownership of the complete thermal system architecture for spacecraft and satellite programmes. Operating at system level, you will define, develop, and validate thermal control strategies to ensure mission success within the harsh space environment where radiation is the dominant heat transfer mechanism.
This role requires proven experience within space programmes — aerospace-only backgrounds will not be suitable.
