## Description

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems. Its products include Hivemind autonomy software, V-BAT and X-BAT aircraft, and Aechelon simulation and synthetic reality technologies.

As a Staff Fluid and Mechanical Systems Engineer, you will be a hands-on multi-disciplinary owner of fluid-system layouts, thermal transport hardware, and adjacent mechanical design for a Group 5 UAV fighter aircraft. You will apply first-principles engineering to develop ram-air circuits, liquid cooling systems, ECS/TMS fluid architecture, and supporting mechanical installations that are buildable, maintainable, and ready for vehicle integration.

## Required Qualifications:

- 6+ years of fluid systems design, thermal systems analysis, or mechanical systems installation experience in aerospace or a comparable regulated industry.

- B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or a related technical discipline.

- Deep mastery of thermodynamics, fluid dynamics, heat transfer, mechanical design fundamentals, and tolerance stack-up methodologies.

- Demonstrated capability with fluid system sizing and analysis, including pressure drop, flow networks, heat transfer, and 1D fluid or thermal system modeling.

- Demonstrated ability to create fluid-system layouts and mechanical installations that satisfy routing, packaging, maintainability, structural-interface, and vehicle-integration requirements.

- Experience in 3D CAD modeling, routing, layouts, and drawing release with Siemens NX, CATIA, Creo, SolidWorks, or equivalent PLM workflows.

- Hands-on capability designing brackets, mounts, supports, and installation hardware using hand calculations, tolerance analysis, and basic structural analysis.

- Proven track record sourcing COTS/custom aerospace components, driving suppliers to schedule, and assembling benchtop or vehicle-level test setups.

- Demonstrated ability to self-direct, prioritize technical tasks without oversight, and deliver functional hardware under tight timelines.

## Preferred Qualifications:

- Aircraft ram-air, liquid cooling, hydraulic, fuel, or thermal transport loop design experience.

- ECS or thermal management system design and integration experience.

- Experience with electro-mechanical or electro-hydrostatic actuation systems and associated mechanical installations.

- Familiarity with MIL-STD-810, MIL-HDBK-516, and airworthiness verification planning for fluid and mechanical systems.

- Hands-on prototype-build, fabrication, or mechanical assembly experience in a rapid R&D environment.

- Eligible to obtain a Secret clearance.

## Additional Information:

- Full-time regular employee offer package: Pay within range listed + Bonus + Benefits + Equity

- Temporary employee offer package: Pay within range listed above + temporary benefits package (applicable after 60 days of employment)

- Salary compensation is influenced by a wide array of factors including but not limited to skill set, level of experience, licenses and certifications, and specific work location.
