Guidance, Navigation, and Control; GNC 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 Controls Engineer
, you’ll help shape the way a revolutionary new class of vehicle moves. You’ll contribute to the development of the seaglider’s flight‑control logic – ensuring it remains stable, responsive, and safe as it seamlessly transitions from displacement to hydrofoil to wing‑in‑ground‑effect flight. Your work will coordinate aerodynamic and hydrodynamic surfaces into a unified, intelligent system that can gracefully handle gusts, waves, and the unexpected.

Through high‑fidelity simulation, hardware‑in‑the‑loop testing, and hands‑on tuning during sea trials, you’ll play a key role in turning cutting‑edge control theory into a certifiable, real‑world mobility solution that changes how coastal regions connect.

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 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!

• 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.

• Proven track record of designing and flight‑testing control systems for aircraft, UAS, or similarly complex vehicles, driven by a deep passion for advancing control in multi‑modal, high‑coupling environments where safety, stability, and performance must coexist.

• Strong theoretical foundation in control theory, plus hands‑on application to real systems.

• Proven design of real‑world control systems and state‑estimation filters.

• Experience designing control algorithms and simulations in MATLAB/Simulink.

• Demonstrated safety & quality mindset in regulated or mission‑critical programs.

• Direct contribution to ARP
