Senior Thermal Engineer

Darwin Space are currently hiring for a Senior Thermal Engineer in Toulouse. Job Description * Lead thermal design efforts from concept through delivery for spacecraft, payloads, electronics, or mechanical systems. * Develop thermal control systems using passive (radiators, insulation, thermal straps) and active (heaters, loop heat pipes, pumped loops) solutions. * Perform thermal modeling and simulation using tools such as Thermal Desktop, ESATAN, Sinda/Fluint, Ansys Icepak, or equivalent.

* Define and manage thermal requirements based on mission needs and environmental constraints. * Develop and maintain thermal mathematical models (TMMs) at both component and system levels. * Ensure proper thermal interfaces between subsystems (mechanical, electrical, payload, etc.). * Develop and execute thermal test plans including: Thermal balance tests, Thermal vacuum tests (TVAC), Bakeout and thermal cycling, Correlate thermal models with test data and refine predictions accordingly.

* Prepare technical documentation, including thermal design reports, analyses, test plans, and compliance matrices. * Support internal and customer design reviews (SRR, PDR, CDR, TRR). * Mentor junior engineers and guide best practices in thermal design and simulation. * Provide technical leadership within multidisciplinary project teams. Requirements * Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related discipline.

* Minimum 5-10 years of experience in thermal engineering, ideally in the space or aerospace sector. * Proficiency with thermal simulation software and experience with spacecraft or high-reliability electronics thermal design. * Knowledge of applicable standards (e.g., ECSS-E-30-01, NASA-STD-7009, MIL-STD thermal test practices). * Strong analytical, problem-solving, and documentation skills. Darwin Recruitment is acting as an Employment Agency in relation to this vacancy.
