Senior Thermal System Engineer Verified today

The Role

Join ICEYE's Spacecraft Hardware team in Espoo, Finland as a Senior Thermal System Engineer. You will design and implement thermal systems for the world's largest SAR satellite constellation, working hands-on from early concept through flight qualification and operations support.

Your Responsibilities

• Design and implement full spacecraft-level thermal models for current and next-generation spacecraft
• Specify and support qualification testing at subsystem and system level, including TVAC testing and model correlation
• Own thermal hardware end-to-end: propose new thermal design concepts, identify suppliers, and test and validate component designs
• Perform thermal analysis of passive and active thermal control components, electrical assemblies, subsystems, and systems
• Support assembly, integration, and test (AIT) activities, including maintenance of thermal control components
• Support operations teams in resolving thermal issues during Launch and Early Orbit Operations (LEOP) and beyond
• Ensure on-time product delivery from concept through qualification
• Contribute to continuous improvement of existing products
• Partner closely with hardware engineering domains, AIT engineering, and QA to ensure products meet specification
• Work with system and subsystem engineers to define thermal requirements for new products
• Collaborate with internal and external engineering teams during integration and build to confirm thermal solutions meet requirements

What You Need

Must have:

• Extensive experience in thermal simulation as a Thermal Engineer in the space industry
• Experience with TVAC testing and model correlation
• Proactive, self-directed working style
• Strong troubleshooting and analytical skills
• Based in Espoo (up to 30% remote work acceptable)
• Experience working in multi-disciplinary environments (electrical, AIT, mechanical, propulsion, RF)
• Experience with thermal control of satellites at system and subsystem level, or comparable complex aerospace systems
• Comfortable working cross-functionally with systems, electrical, and manufacturing teams
• Strong teamwork, analytical, documentation, and communication skills

Nice to have:

• Hands-on experience with spacecraft thermal hardware: surface treatments, MLI, passive and active thermal control components, heat pipes
• Experience with Systema-Thermica, ESATAN, and/or Thermal Desktop
• MSc in Aerospace Engineering
• Knowledge of SAR satellite technology, lifecycles, and the space environment
• Experience with Python
• Familiarity with industry standards such as ECSS and NASA standards
• Solid understanding of spacecraft configurations, orbits, and STK
