Senior Thermal Engineer H/F Infinite Orbits

To complete our dynamic and international team, we are looking for a Senior Thermal Engineer to lead the thermal design, analysis, and verification of high-performance systems such as spacecraft, satellites, avionics, or aerospace structures. This role involves ownership of thermal subsystem architecture, modelling, and validation, ensuring thermal control requirements are met under a wide range of operating conditions.

Job Description

Thermal Design & Analysis

• 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.

System Integration & Requirements

• 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.).

Verification & Testing

• 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.

Documentation & Reporting

• Prepare technical documentation, including thermal design reports, analyses, test plans, and compliance matrices.
• Support internal and customer design reviews (SRR, PDR, CDR, TRR).

Mentorship & Leadership

• Mentor junior engineers and guide best practices in thermal design and simulation.
• Provide technical leadership within multidisciplinary project teams.
