Spacecraft Thermal Systems Architect (m/f/d)

Deine Mission

Transverse role with significant growth opportunity in our Orbital Systems team in Munich. You'll own thermal as a domain across our versatile multi-orbit spacecraft — from system proposals and pre-development through detailed definition, qualification, and flight-data analysis — at both system and subsystem level. As our programs and team scale, you'll build and lead the thermal function: hiring, mentoring, and setting the standards. You don't need to have run a team before, but you should want to, and be ready to grow into it with our support.

You will

• Implement and analyse associated 2D and 3D thermal models (ESATAN-TMS, Systema, Thermal Desktop or equivalent)
• Coordinate across disciplines and bring a systems vision
• Contribute to MBSE models and ways of working
• Derive and manage thermal requirements
• Support integration and verification activities (TVAC and others) at subsystem and system level

Dein Profil

Several years in spacecraft thermal engineering with a track record of owning thermal at architecture level — typically multiple years as a thermal engineer plus 2+ in a thermal architecture or lead role. We're equally interested in significantly more senior profiles (10+ years in thermal systems architecture) and will level the role and compensation accordingly.

Motivation and clear trajectory toward technical leadership and team-building; prior line-management experience is a plus, not a prerequisite.

Strong understanding of underlying physical principles for thermal engineering

Analysis tools and TVAC testing knowledge

Knowledge of Systems Engineering practices including Requirements Engineering; ECSS

Passion for creating a new spaceflight paradigm (space logistics & orbital refuelling)

Strong analytical and communication skills

Accountable with an agile mindset
