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. This position requires a balance of technical rigor, rapid decision-making, and hands-on engineering to efficiently transition concepts into operational capability. The ideal candidate is comfortable solving complex problems, taking ownership, working within an accelerated aircraft development environment, and is motivated by getting meaningful capability into the hands of operators quickly.
REQUIRED QUALIFICATIONS:
-
- Experience: 6+ years of fluid systems design, thermal systems analysis, or mechanical systems installation experience in aerospace or a comparable regulated industry.
- Education: B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or a related technical discipline.
- Core Fundamentals: Deep mastery of thermodynamics, fluid dynamics, heat transfer, mechanical design fundamentals, and tolerance stack-up methodologies.
- Modeling and Analysis: Demonstrated capability with fluid system sizing and analysis, including pressure drop, flow networks, heat transfer, and 1D fluid or thermal system modeling.
- System Layout and Integration: Demonstrated ability to create fluid-system layouts and mechanical installations that satisfy routing, packaging, maintainability, structural-interface, and vehicle-integration requirements.
- CAD and PLM: Experience in 3D CAD modeling, routing, layouts, and drawing release with Siemens NX, CATIA, Creo, SolidWorks, or equivalent PLM workflows.
- Mechanical Design: Hands-on capability designing brackets, mounts, supports, and installation hardware using hand calculations, tolerance analysis, and basic structural analysis.
- Hardware and Supplier Execution: Proven track record sourcing COTS/custom aerospace components, driving suppliers to schedule, and assembling benchtop or vehicle-level test setups.
- Autonomy: 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.
