Senior Thermal Engineer

Senior Thermal Engineer – Space Systems Location: Westminster, Colorado

Employment: Full-time | On-site

Industry: Space & Aerospace

EVONA is partnering with a fast-growing space technology company developing advanced communications hardware for satellites, spacecraft and airborne platforms.

We’re looking for a Senior Thermal Engineer to take ownership of the thermal design, analysis and validation of next-generation space hardware.

This is a highly technical, hands-on role where you’ll work alongside mechanical, electrical and RF engineers to develop thermal solutions for sophisticated electronics from initial concept through analysis, manufacturing, testing and qualification .

What You’ll Be Doing

• Own thermal design and analysis for spacecraft electronics, PCBAs, enclosures and integrated systems.
• Perform detailed conductive, convective and radiative heat-transfer analysis.
• Develop thermal models using tools such as ANSYS or Thermal Desktop.
• Build thermal resistance networks and reduced-order models for complex systems.
• Support thermal chamber and TVAC testing, correlating test results back to analytical models.
• Work closely with mechanical, electrical and RF engineering teams to optimize hardware designs.
• Develop scripts and tools to automate thermal analysis.
• Support design reviews, qualification activities and technical presentations.

What We’re Looking For

• BS or higher in Mechanical, Thermal or Aerospace Engineering.
• 5+ years of industry experience in thermal/mechanical design and analysis.
• Strong experience with electronics thermal management, including PCBA, box and system-level hardware.
• Excellent understanding of heat transfer and mechanical engineering fundamentals.
• Experience with ANSYS, Thermal Desktop or similar professional thermal simulation tools.
• Experience correlating analytical models with thermal chamber or TVAC testing.
• Understanding of manufacturing processes relevant to thermal control hardware.
• Ability to work on-site in Westminster, Colorado.

Highly Desirable

• Spacecraft or satellite thermal engineering experience.
• Thermal management of phased arrays, antennas or high-power RF electronics.
• Die, package or component-level electronics thermal analysis.
• SolidWorks experience.
• Python, MATLAB or similar scripting experience.

Why This Role?

You’ll work directly on advanced hardware destined for demanding space and aerospace environments , with genuine ownership over thermal performance from early-stage design through qualification.

This is an excellent opportunity for an experienced thermal engineer who wants to stay technically hands-on while solving challenging thermal problems on next-generation space hardware.
