Shield AI
Principal Thermal Engineer - Aircraft Avionics & Thermal Systems (R3930)
Shield AI, Granite Heights, Wisconsin, United States
Shield AI is a venture-backed deep-tech company with the mission of protecting service members and civilians with intelligent systems. Its products include the V-BAT aircraft, Hivemind Enterprise, and the Hivemind Vision product lines.
We are seeking a passionate and innovative thermal engineer to help develop state of the art AI and aircraft products. As a Principal Thermal Engineer at Shield AI, you will own and drive the architecture, design, and integration of avionics and aircraft-level thermal management systems, with opportunities to influence fluid systems and multidisciplinary designs.
What you'll do:
Lead thermal analysis and design efforts for unmanned aerial vehicle avionics and aircraft-level thermal/fluid systems. Architect and validate analytical, numerical, and computational models for heat transfer and fluid flow using hand calculations and CFD tools such as FloEFD. Provide leadership in trade studies, system architecture decisions, and technical risk assessments. Define and oversee test planning, instrumentation, and data analysis to correlate models with experimental results. Mentor and guide cross-disciplinary teams in applying thermal/fluid fundamentals. Communicate technical findings through executive-level briefings, design reviews, and technical reports. Proactively identify program risks, propose solutions, and influence avionics and PCBA design direction. Represent Shield AI in technical reviews, proposals, and customer interactions. Required qualifications:
B.S. in Mechanical Engineering, Aerospace Engineering, or related discipline. Minimum 12 years of professional experience in avionics or electronics thermal engineering. Deep expertise in heat transfer (conduction, convection, radiation) and fluid mechanics. Advanced understanding of active and passive cooling solutions and their integration at the component and system level. Advanced knowledge 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 ability to apply first-principles reasoning to complex engineering problems. Strong communication and leadership skills, with experience presenting to executives and customers. Preferred qualifications:
M.S. or Ph.D. in a relevant engineering discipline. Extensive experience with high-altitude aircraft avionics cooling and thermal design. Familiarity with aircraft integration constraints (power, weight, volume, maintainability, safety). Hands-on experience with thermal and fluid system testing, instrumentation, and validation. Knowledge of materials and manufacturing methods relevant to aerospace thermal management. Experience guiding trade studies, proposals, and customer interactions in aerospace or defense programs. Background in multi-disciplinary system integration, spanning avionics, fluid systems, and systems engineering. Shield AI is proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, marital status, disability, gender identity or Veteran status. If you have a disability or special need that requires accommodation, please let us know.
