Power Electronics - Thermal Engineer Senior Staff

Job description

Job Description: Are you a passionate and innovative thermal engineer looking to help develop state of the art aircraft? Are you eager to make a positive difference in the world? Do you want to work alongside mission driven and values focused teammates? Shield AI is just the place for you! As a Senior Staff Thermal Engineer at Shield AI, you will lead the design, analysis, and integration of aircraft avionics thermal management systems. We are designing a high voltage, high power system using custom power electronics and energy storage.

Job responsibilities

  • Own thermal analysis and design efforts for unmanned aerial vehicle avionics including custom power electronics
  • Develop and validate analytical, numerical, and computational models for heat transfer and fluid flow using hand calculations and CFD tools such as FloEFD
  • Provide technical leadership in trade studies, system architecture decisions, and risk assessments
  • Lead cross-functional teams designing power electronic circuits and environmental enclosures. Provide design requirements that impact circuit part selection, board layout, material selection, and other design aspects
  • Drive test planning, instrumentation, and data analysis to correlate models with experimental results
  • Mentor junior engineers and guide cross-disciplinary teams in applying thermal/fluid fundamentals
  • Communicate technical findings clearly through executive-level briefings, design reviews, and written reports
  • Proactively identify risks, propose solutions, and influence electrical and/or PCBA design direction

Job requirements

  • B.S. in Mechanical Engineering, Aerospace Engineering, or related discipline
  • Minimum 7 years of professional experience in avionics or electronics thermal engineering
  • Strong expertise in heat transfer (conduction, convection, radiation) and fluid mechanics
  • Deep understanding of active and passive cooling solutions and their integration at component and system level
  • Deep 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+)
  • Proficiency with CAD design tools such as NX, SolidWorks, or similar
  • Demonstrated experience applying first-principles reasoning to complex engineering problems
