REGENT is building Seagliders—wing-in-ground-effect craft that travel just above the water's surface, combining airplane speed (180 mph) with boat-like operating costs. The company is scaling from prototype to full production and seeking a Mechanical Design Engineer to own mechanical systems across multiple vehicle platforms (Squire, Paladin, Viceroy). In this hands-on role, you will design, refine, and mature mechanical systems spanning structures, mechanisms, actuation, fluid handling, and vehicle-level integration. You'll take subsystems from concept through CAD, analysis, prototype, and test. Key responsibilities include: - Design mechanical hardware across structures, mechanisms, actuation, thermal, fluid, and electromechanical systems from concept through production-intent CAD and documentation. - Justify designs with analysis—hand calculations, structural FEA, kinematic analysis, thermal analysis, and fluid analysis as needed, including fastener sizing and tolerance stack-ups. - Build and test prototypes in the lab with limited supervision; design test rigs, benches, and fixtures to enable rapid iteration. - Mature existing designs already deployed on REGENT products, improving reliability, weight, and manufacturability for production. - Partner across electrical, software, controls, and program management teams to solve integration challenges. - Own projects end-to-end as the responsible engineer, progressing multiple concepts in parallel while tracking trade-offs. - Contribute to core technologies like hydrofoil retraction and control surface actuation, moving them from prototype toward full-rate production. Within a year, you'll be shaping mechanical system architectures and making sound engineering decisions with limited oversight, becoming a trusted technical focal point for one or more areas of ownership. REQUIREMENTS: - Demonstrated mechanical design experience across a variety of system types: structures, mechanisms, actuation, thermal, fluid, or electromechanical. - Strong command of machine elements and mechanisms—bearings, locks, latches, hinges, linkages, seals, pulleys, sliders—ideally having designed systems using several. - Familiarity with drive and power transmission: motors, gearboxes, gear trains, belt and chain drives, and hydraulics. Experience selecting fastening and joining schemes and sizing joints. - Advanced CAD proficiency designing complex components and large assemblies (NX preferred but not required), with clean, well-organized models. - Solid analysis foundation: comfortable with hand calculations and FEA to justify design choices, with sound judgment about which analysis a system needs. - Practical manufacturing knowledge: machining, sheet metal, composites, welding, castings, and additive manufacturing, plus understanding of how each shapes design decisions, materials selection, and failure modes (fatigue, corrosion, wear, buckling). - Bonus: structural analysis depth (FEMAP or ANSYS experience). - Bonus: eVTOL or flight-hardware background, designing flight-worthy human-carrying assets with breadth across multiple mechanical disciplines.
