## 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

## Skills

### Required
- 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
- 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
- Strong written and verbal communication skills, with a track record of leading technical discussions and presenting to stakeholders
