Senior Thermal Engineer

Location: Westminster, Colorado

Industry: Space & AerospaceEVONA is partnering with a fast-growing space technology company developing advanced communications hardware for satellites, spacecraft and airborne platforms. We're looking for aSenior Thermal Engineerto 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 frominitial concept through analysis, manufacturing, testing and qualification .

What You'll Be Doing: Own thermal design and analysis forspacecraft electronics, PCBAs, enclosures and integrated systems .Perform detailedconductive, convective and radiative heat-transfer analysis .Develop thermal models using tools such asANSYS or Thermal Desktop .Buildthermal resistance networks and reduced-order modelsfor complex systems. Support thermal chamber andTVAC 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 inMechanical, Thermal or Aerospace Engineering .5+ years of industry experiencein thermal/mechanical design and analysis. Strong experience withelectronics thermal management, including PCBA, box and system-level hardware. Excellent understanding ofheat transfer and mechanical engineering fundamentals .Experience withANSYS, Thermal Desktop or similar professional thermal simulation tools .Experience correlating analytical models withthermal chamber or TVAC testing .Understanding of manufacturing processes relevant to thermal control hardware. Ability to workon-site in Westminster, Colorado .Highly Desirable Spacecraft or satellite thermal engineering experience. Thermal management ofphased arrays, antennas or high-power RF electronics .Die, package or component-level electronics thermal analysis.

Solid: Worksexperience. Python, MATLAB or similar scripting experience. Why This Role? You'll work directly on advanced hardware destined for demandingspace 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.
