Staff Mechanical Design Engineer

About the role

You will own the end-to-end mechanical design of critical motion systems that define how the Seaglider operates in its marine environment. This position requires you to conceive, simulate, and prototype mechanisms that are both high-performing and manufacturable for a new class of vehicle. You will be responsible for translating abstract vehicle requirements into precise mechanical architectures that survive real-world testing. Your work will directly influence the reliability and functionality of hydrofoil retraction and control surface actuation. You will act as a technical leader, guiding complex mechanism development from initial sketches through to production hardware. This role demands a bias for action, where analysis is quickly followed by fabrication and data-driven iteration. If you are motivated by solving hard problems that impact how people move across water, this is your opportunity.

Key facts

What you'll do

• Own the design and development of complex mechanical and actuation systems across REGENT platforms, including hydrofoil retraction, control surfaces, and motion-critical subsystems.
• Define system architectures and design approaches for mechanisms involving linkages, transmissions, motors, and integrated motion systems.
• Design, build, and iterate on test assets, fixtures, and rigs that enable rapid validation and de-risking of new concepts.
• Translate high-level vehicle requirements into detailed mechanical designs, balancing performance, reliability, manufacturability, and safety.
• Perform and lead kinematic, dynamic, and structural analyses (hand calculations and FEA) to validate designs and guide trade studies.
• Partner cross-functionally with electrical, controls, avionics, and test teams to integrate sensors, actuators, and control systems into cohesive solutions.
• Lead root cause investigations and drive design improvements based on test data and field performance.
• Develop high-quality CAD models, drawings, and documentation that clearly communicate design intent across teams.
• Establish best practices for mechanism design, DFMA, tolerance analysis, and system integration as REGENT scales.
• Mentor engineers and elevate the technical capability of the mechanical team.

Requirements

You must have proven experience designing complex mechanical systems involving linkages, gear trains, transmissions, hinges, or similar kinematic systems. You must possess a deep understanding of motors, gearboxes, and industrial motion control systems, including servo motors, BLDC systems, and associated drive electronics. You must demonstrate advanced CAD proficiency, with a preference for NX, and experience designing large assemblies and production-ready components. You must have a strong foundation in engineering analysis, including kinematics, force and torque estimation, tolerance analysis, and structural evaluation through FEA. You must have hands-on experience building, testing, and troubleshooting mechanical systems in laboratory or field environments. You must have experience working effectively across multidisciplinary teams alongside electrical, controls, and software engineers. You must have a strong understanding of DFMA principles, GD&T, and tolerance stack-ups. You must demonstrate the ability to independently drive projects from initial concept through validation, iteration, and final delivery.

About the role

You will define and drive the design of complex mechanical and actuation systems that are fundamental to how our vehicles move, control, and operate. This role blends deep mechanism design expertise with hands-on development - spanning concept generation, prototype builds, test infrastructure, and production-ready system design.

You will operate across both vehicle systems and test platforms, contributing directly to kinematic system design (e.g., hydrofoil retraction, control surface actuation) while also enabling rapid iteration through the development of test assets, rigs, and demonstrators.

This is a highly cross-functional role working at the intersection of mechanical, electrical, controls, and test engineering. You will bring technical leadership, strong engineering judgement, and a bias toward execution - helping REGENT scale from prototype to production without compromising safety.

If you're energized by working at the intersection of cutting-edge innovation, real-world impact, and hands-on engineering, you'll be in the right place - and we'd be thrilled to have you on the team!
