This is an exciting opportunity to work on cutting-edge technology, collaborating with mechanical, electrical, and RF engineering teams to develop high-performance thermal solutions from initial concept through manufacturing, testing, and qualification.

Key Responsibilities

• Design and analyze thermal management solutions for spacecraft electronics, PCBAs, enclosures, and integrated systems.
• Perform conductive, convective, and radiative heat-transfer analysis.
• Develop and validate detailed thermal models using ANSYS, Thermal Desktop, or similar simulation tools.
• Build thermal resistance networks and reduced-order thermal models.
• Support thermal chamber and TVAC testing, correlating analytical models with test results.
• Collaborate with cross-functional engineering teams to optimize thermal performance.
• Develop automation tools and scripts to improve thermal analysis processes.
• Support technical design reviews, manufacturing, and hardware qualification.

Requirements

• Bachelor's degree or higher in Mechanical, Thermal, Aerospace Engineering, or a related discipline.
• 5+ years of experience in thermal/mechanical engineering, design, and analysis.
• Strong experience in electronics thermal management, including PCBA, box-level, and system-level thermal design.
• Proficiency with ANSYS, Thermal Desktop, or equivalent thermal simulation software.
• Strong understanding of heat-transfer principles, including conduction, convection, and radiation.
• Experience developing thermal resistance networks and reduced-order models.
• Experience with thermal testing, model correlation, and environmental qualification.
• Familiarity with mechanical CAD tools such as SolidWorks.
• Ability to work on-site in Westminster, Colorado.

Preferred Qualifications

• Experience with spacecraft, satellite, or aerospace thermal control systems.
• Thermal management experience with phased arrays, antennas, or high-power RF electronics.
• Experience analyzing electronics at the die, package, or component level.
• Proficiency in Python, MATLAB, or similar scripting languages.
• Experience supporting flight hardware development and TVAC qualification.

Why Apply?

• Work on advanced communications hardware for space and aerospace applications.
• Take ownership of challenging thermal engineering projects from concept to qualification.
• Collaborate with highly skilled engineers across multiple disciplines.
• Join a fast-paced, innovative engineering environment.
• Competitive compensation, benefits, and opportunities for professional growth.
