About The Position

Sceye is seeking a Thermal Engineer to join our Avionics Hardware (HW) team. This role is responsible for the thermal design, analysis, and validation of avionics hardware operating in a challenging stratospheric environment. The ideal candidate will collaborate closely with electrical, mechanical, systems, and flight operations teams to ensure avionics performance, reliability, and safety across all mission phases.

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 5+ years of experience in thermal engineering, preferably within aerospace, avionics, or high-reliability electronics.
• Strong understanding of heat transfer principles (conduction, convection, radiation).
• Experience performing thermal analysis of electronic hardware and assemblies.
• Familiarity with thermal modeling and analysis tools (e.g., Thermal Desktop, SINDA/FLUINT, ANSYS, COMSOL, or equivalent).
• Experience supporting environmental testing and correlating test data to analysis.
• Ability to work cross-functionally with electrical, mechanical, and systems engineers.
• Strong documentation, communication, and presentation skills.

Nice To Haves

• Master’s degree in Mechanical or Aerospace Engineering.
• Experience with high-altitude, space, or near-space environments.
• Knowledge of PCB thermal design and power electronics thermal management.
• Experience with thermal vacuum (TVAC) testing and qualification programs.
• Familiarity with aerospace standards and best practices for environmental qualification.
• Hands-on experience with avionics hardware development from concept through flight.

Responsibilities

• Lead thermal analysis and design for avionics hardware, including PCBs, enclosures, and integrated avionics assemblies.
• Develop and validate thermal models using analytical and numerical methods (e.g., conduction, convection, radiation).
• Perform steady-state and transient thermal analyses to support design decisions and mission requirements.
• Define thermal requirements and margins for avionics systems operating in high-altitude, low-pressure, and extreme temperature environments.
• Support hardware layout and enclosure design to optimize heat dissipation and component placement.
• Specify and evaluate thermal management solutions, including heat sinks, thermal interface materials (TIMs), coatings, and passive/active cooling approaches.
• Plan, support, and analyze thermal testing (e.g., thermal vacuum, thermal cycling, environmental testing).
• Correlate test results with models and update analyses as designs evolve.
• Support design reviews (PDR, CDR) with clear documentation and technical presentations.
• Collaborate with systems engineering to ensure thermal performance aligns with power, reliability, and mission requirements.
• Contribute to failure analysis, root cause investigations, and corrective actions related to thermal issues.
