  • Provide technical leadership in trade studies, system architecture decisions, and risk assessments.
  • Drive test planning, instrumentation, and data analysis to correlate models with experimental results.
  • Guide cross-disciplinary teams in applying thermal/fluid fundamentals.
  • Communicate technical findings clearly through design reviews, and written reports.
  • Proactively identify risks, propose solutions, and influence electrical and/or PCBA design direction.

Requirements:

  • B.S. in Mechanical Engineering, Aerospace Engineering, or related discipline.
  • Minimum 4 years of professional experience in avionics or electronics thermal engineering.
  • Strong expertise in heat transfer (conduction, convection, radiation) and fluid mechanics.
  • Strong understanding of active and passive cooling solutions and their integration at component and system level.
  • Understanding of thermal management design elements including TIMs, spreaders, heat sinks, vapor chambers, heat pipes, and fans.
  • Proficiency with thermal analysis and CFD tools (e.g., ANSYS Icepak, FloEFD, STAR-CCM+).
  • Experience with CAD design tools such as NX, SolidWorks, or similar.
  • Demonstrated experience applying first-principles reasoning to complex engineering problems.
