Senior Thermal Engineer

Role highlights:

Thermal Engineer

Location: Warsaw, Poland

Department: Engineering/Optical Systems

Reports to: Engineering Lead, Mechanical Engineering

Employment type: Permanent

Workplace model: Hybrid

Employment is subject to applicable security screening (incl. SUPO, where required)

Why this role matters:

As a Thermal Engineer, you will own the thermal design of ICEYE's next generation satellite platform and its imaging payload, making sure both stay within temperature limits and hold the precise thermal stability the instrument needs. Working hands-on across simulation, hardware, and test, you will drive thermal analysis at system level, take ownership of thermal control hardware from concept and supplier selection through validation, and guide material choices for the space environment. As a founding member of a small team, you will follow the design through every stage of the product lifecycle, from concept and prototyping to assembly, integration, TVAC and thermal balance testing, qualification, and in-orbit validation.

Who We Are

ICEYE is the world leader in sovereign intelligence from space. We deliver persistent monitoring capabilities to detect and respond to changes in any location on Earth.

ICEYE owns the world's largest and most advanced SAR (synthetic aperture radar) satellite constellation. To our customers we provide intelligence with unmatched quality, latency and revisit times, in any weather, day or night. To governments who choose to operate their own constellation we provide this proven capability as a sovereign system.

ICEYE-built constellations serve customers in defence and intelligence, environmental monitoring, insurance and emergency management. We enable fast decisions that contribute to a safer future.

Founded and headquartered in Finland, ICEYE operates globally with over 1000 employees across Europe, North America, the Middle East, and Asia-Pacific.

Your day-to-day responsibilities

Be a key founding member of the small team responsible for the spacecraft systems lifecycle, from design up to in-orbit validation. The team will bring the design into full production, commissioning, and operations of the imaging instrument, including all phases along the way: testing, qualification, verification, and iterating on necessary steps.

Be a technical leader for thermal design and optimization of the satellite platform and the interfaces between bus and payload. Due to the nature of the project and the size of the founding "tiger team," you're expected to actively (hands-on) participate in thermal hardware assembly and other engineering activities, including thermal testing and close cooperation with other team members.

Drive thermal design and simulation of the next-generation satellite, performing thermal analysis at the system level.

Collaborate with subcontractors during the development phase.

Specify and support qualification tests at the system level, making sure thermal performance meets requirements.

Take ownership of thermal hardware: propose new concepts to optimize thermal performance, propose new suppliers, and test and validate the design.

Support assembly, integration, and test activities: maintain thermal control component definitions and specify qualification tests.
