Job Description:
Are you a passionate and innovative thermal engineer looking to help develop state of the art AI and aircraft products? 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 Sr. Staff Thermal Engineer at Shield AI, you will lead the design, analysis, and integration of aircraft avionics thermal management systems, with opportunities to flex into aircraft-level thermal and fluid systems.
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.
What you'll do::
-
Own thermal architecture, analysis, and design strategy for unmanned aerial vehicle avionics and aircraft-level thermal/fluid systems across programs.
-
Lead cross-functional trade studies and technical decisions, balancing thermal performance with power, weight, volume, reliability, manufacturability, and aircraft integration constraints.
-
Develop and validate analytical, numerical, and computational models for heat transfer and fluid flow using hand calculations and CFD tools such as FloEFD, and establish modeling standards and best practices.
-
Define verification and validation strategies, guiding test planning, instrumentation, and data analysis to correlate models with experimental results and resolve critical performance risks.
-
Serve as a technical authority in executive-level briefings, design reviews, and customer discussions, communicating complex findings and driving alignment on technical direction.
-
Proactively identify and retire system-level risks, influence electrical and/or PCBA design direction, and drive resolution of complex interfaces across avionics, mechanical, and aircraft systems.
-
Establish reusable thermal design methods and solutions, mentor engineers, and strengthen thermal engineering capabilities across the organization.
Required qualifications::
-
B.S. in Mechanical Engineering, Aerospace Engineering, or related discipline.
-
Minimum 12 years of professional experience in avionics or electronics thermal engineering, including technical leadership of complex, multidisciplinary systems.
-
Strong expertise in heat transfer (conduction, convection, radiation) and fluid mechanics, with demonstrated ability to apply this expertise to system architecture and critical design decisions.
-
Deep understanding of active and passive cooling solutions and their integration at component, subsystem, and aircraft 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+), including experience establishing modeling approaches and evaluating analysis quality.
-
Proficiency with CAD design tools such as NX, SolidWorks, or similar.
-
Demonstrated experience applying first-principles reasoning to complex engineering problems and resolving ambiguous technical challenges with significant system-level impact.
-
Proven track record of owning thermal architecture and delivering thermal management solutions from concept through integration, verification, and validation.
-
Strong written and verbal communication skills, with a track record of influencing cross-functional technical decisions and presenting to executive stakeholders.
-
Demonstrated ability to mentor engineers, establish engineering best practices, and lead technical efforts across teams or programs.
-
Proven ability to learn and adapt quickly to new tools, processes, and technical challenges in a fast paced, startup environment.
-
Ability to obtain a S//SAR level security clearance desired.
Preferred qualifications::
-
M.S. or Ph.D. in a relevant engineering discipline.
-
Experience leading high altitude aircraft avionics cooling and thermal design.
-
Experience defining thermal architectures within aircraft integration constraints (power, weight, volume, maintainability, safety).
-
Hands-on experience developing thermal and fluid system test strategies and guiding instrumentation, validation, and root-cause investigations.
-
Knowledge of materials and manufacturing methods relevant to thermal management (pumps, heat exchangers, composites, etc.).
-
Experience leading trade studies, shaping proposals, and serving as a technical representative in customer interactions on aerospace or defense programs.
