Mechanical Design Engineer

At REGENT, we’re on a mission to revolutionize regional transportation between coastal cities. We're not just building vehicles, we're creating a new category of transportation: the Seaglider. These groundbreaking wing-in-ground-effect craft travel just above the water’s surface, combining the speed of an airplane with the low operating costs of a boat. Capable of 180 miles at 180 mph on today's battery tech (and up to 400 miles with next-gen batteries), Seagliders will unlock fast, affordable, and sustainable coastal transit for passengers and cargo - connecting cities, islands, and communities like never before.

Backed by leading investors and powered by a team of passionate, forward-thinking engineers, builders, and operators, we’re now scaling from a breakthrough prototype to full production - and building the team to make it happen.

As a Mechanical Design Engineer at REGENT, you'll design, refine, and mature the mechanical systems that make our Seagliders work — spanning structures, mechanisms, actuation, fluid handling, and vehicle-level integration. This is a hands-on design role on our Hardware Engineering team, and it exists because we're scaling from a prototype environment toward full-rate production and need dedicated design capacity to improve, troubleshoot, and harden the wide variety of mechanical systems across our platforms.

You'll own mechanical design work across Squire, Paladin, and Viceroy — taking subsystems and mechanisms from concept through CAD, analysis, prototype, and test. You'll size fasteners and joints, run the hand calculations and analyses that justify a design, build and test prototypes in the lab, and work shoulder-to-shoulder with our electrical, software, and program management teams to close integration challenges. Over time, you'll become a technical focal point for one or more areas of ownership.

Success in this role looks like becoming a trusted, go-to contributor: independently progressing designs, identifying real issues rather than just executing tasks, and helping mature key REGENT technologies like hydrofoil retraction and control surface actuation toward production. Within a year, you'll be shaping mechanical system architectures and making sound engineering decisions with limited oversight.

• Design mechanical hardware across a range of systems — structures, mechanisms, actuation, thermal, fluid, and electromechanical — from concept through production-intent CAD and documentation.

• Justify your designs with analysis — hand calculations plus structural (FEA), kinematic (range of motion, power, torque), thermal, or fluid analysis as the system demands, including fastener sizing and tolerance stack-ups.

• Build and test prototypes in the lab — validate concepts hands-on with limited supervision, and design or improve the test rigs, benches, and fixtures that let the team iterate quickly on real data.

• Re-envision and mature existing designs — improve mechanical systems already deployed on REGENT products, strengthening reliability, weight, and manufacturability for production.

• Partner across disciplines — interface directly with electrical, software, and controls teams to solve integration challenges, and work with program management to keep projects on schedule.

• Own projects end-to-end — serve as the responsible engineer for assigned design investigations from kickoff to completion, progressing multiple concepts in parallel while tracking their trade-offs.

• Advance key REGENT technologies — contribute to core systems like hydrofoil retraction and control surface actuation, helping move them from prototype toward full-rate production.

• Demonstrated mechanical design experience across a variety of system types —…
