Description

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.

This role is best suited for an engineer who thrives on first-principles problem solving, is comfortable with ambiguous, open-ended challenges, and can bridge technical disciplines with strong communication and collaboration skills and the ability to simplify and communicate complex problems.

The engineer will be a key contributor in shaping designs, mentoring peers, and ensuring robust thermal solutions that meet mission-critical aerospace requirements.

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
