• Deep understanding of thermo-elastic distortion and dimensional stability.
• Strong knowledge of passive & active thermal control techniques.
• Experience correlating thermal models with thermal balance and TVAC test data.
• Solid understanding of aerospace materials and thermal properties (CTE, conductivity, emissivity).
• Ability to translate RF performance constraints into thermal/mechanical design requirements (efficient thermal dissipation from IC and RF PCBs, EMI/EMC of the enclosure, etc).
• Strong technical documentation and design review participation.

Good-to-have

• Experience with radar or high-frequency RF payloads.
• Familiarity with deployable structures.
• Working knowledge of structural FEA workflows in Simcenter 3D (NX Nastran).
• Experience designing thermal aspects of test support equipment.
• Exposure to spacecraft Bus thermal interface design.
• Experience with heater control electronics and sensor placement strategies.
• Background in thermal-optical property characterization.
• Experience in fast-paced private aerospace or new-space environments.

What We Look For

• Ownership mindset and ability to lead complex thermal design efforts.
• Curiosity and eagerness to solve multidisciplinary challenges.
• Adaptability to fast-paced start-up environments.
• Strong analytical and problem-solving skills.
• Passion for aerospace and enthusiasm to contribute to real-world satellite missions.
• Competitive compensation aligned with market standards.
