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.

Due to U.S. space technology export‑control requirements, applicants must meet applicable U.S.-person eligibility requirements.
