Job DescriptionJob DescriptionAt 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.

Role Overview As a Senior GNC Engineer, you will own the seaglider’s flight-control logic - everything that keeps the craft stable, responsive, and safe as it transitions from displacement to hydrofoil to wing-in-ground-effect flight. You’ll craft control laws that harmonize aerodynamic and hydrodynamic surfaces, manage take-off and touchdown on water, and ensure graceful handling in gusty, wave-affected conditions. You’ll validate your designs in high-fidelity simulation, prove them using hardware-in-the-loop, and refine them on both sub-scale and full-scale prototypes during sea trials. Beyond the technical execution, you’ll shape the future of maritime mobility by developing fault-tolerant control strategies and robust state-estimation loops for a new class of vehicle. You’ll mentor junior engineers, influence our flight-controls roadmap, and help guide our path to certification.

As part of the Software Team, you’ll be joining a group of driven, collaborative, and talented engineers who take pride in solving complex technical challenges and making an impact as a team. We hold a high bar for engineering rigor, move fast, think boldly, and rely on our teamwork to push boundaries and and turn breakthrough ideas into real-world technology.

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!What You'll Do

• Own vehicle control laws : Design and implement control laws for stabilization, mode transitions, envelope protection, and emergency fallbacks that keep the seaglider safe and responsive across all phases of flight.
• Apply safety-critical rigor : Define and trace requirements, lead design / code reviews, and develop rigorous test plans including SIL and HIL to meet certification-grade robustness.
• Simulate, analyze, refine : Use and extend high-fidelity simulation environments (MATLAB / Simulink or custom frameworks) to design and validate GNC algorithms. Perform both linear and nonlinear analysis to evaluate performance and iterate with confidence.
• Integrate multisensor navigation : Develop and optimize state estimation algorithms that integrate GNSS / INS, radar altimeter, and other sensor inputs for reliable positioning in challenging maritime environments.
• Tune with real-world data : Leverage flight test and sea trial data to iteratively refine control algorithms and close the loop between simulation and reality.
• Collaborate across disciplines : Work closely with aero, hydro, mechanical, and systems teams to align on actuator specs, control-surface design, and verification strategies.
• Lead test events : Plan, execute, and analyze full-scale test events to validate and mature flight controls, driving toward a certifiable and production-ready system.
