Job description

Thermal Engineer – Spacecraft & Satellite Systems

EVONA is partnering with a growing space technology company seeking a Thermal Engineer to take ownership of thermal engineering across electronics, spacecraft hardware and satellite systems.

Joining the mechanical team as the company’s dedicated thermal specialist, you’ll work closely with electrical and systems engineers, influencing designs from individual chips and circuit cards through to satellite thermal architecture and performance in orbit.

This is an opportunity to own engineering work from initial assessment through design, integration and verification, with the freedom to help select the analysis tools you use.

The role

• Lead thermal analysis and modelling of circuit cards, electronic assemblies and spacecraft hardware.
• Assess high-density electronics, including VPX circuit cards, and recommend improvements to thermal performance.
• Evaluate heat-transfer paths and satellite performance across different orbital conditions.
• Develop thermal models to support design trades, requirements and system architecture.
• Identify thermal risks and work with engineering teams to implement practical solutions.
• Support thermal vacuum testing, thermal cycling and environmental qualification activities.
• Present findings and recommendations at design reviews and support hardware through build, integration and test.

What you’ll bring

• A degree in Mechanical Engineering, Aerospace Engineering or a related discipline.
• Ideally 3–5 years of relevant professional experience in spacecraft thermal analysis, electronics thermal design or closely related thermal engineering.
• Practical experience independently assessing thermal performance and translating analysis into design decisions.
• Experience using thermal analysis software, with the ability to recommend suitable tools for the work.
• Strong communication skills and confidence working across engineering disciplines.

Experience with satellite thermal architectures, electronic packaging, environmental testing or CAD tools such as SolidWorks would be valuable.

You’ll have broad technical ownership within a growing engineering team, direct access to colleagues across disciplines and few management layers. The team offers a relaxed, collaborative environment where your recommendations can directly shape both electronics and spacecraft designs.

Benefits include healthcare coverage, a matching 401(k) from day one, paid time off, 11 paid holidays and professional development opportunities. Relocation support may be available depending on circumstances.

Applicants must meet the applicable U.S. export-control eligibility requirements.
