Guidance, Navigation, and Control (GNC) Engineer

Guidance, Navigation, and Control (GNC) Engineer

At REGENT, were 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 waters 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, were now scaling from a breakthrough prototype to full production - and building the team to make it happen.

Role Overview

As a Controls Engineer , youll help shape the way a revolutionary new class of vehicle moves. Youll contribute to the development of the seagliders 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, youll 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, youll 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 youre energized by working at the intersection of cutting-edge innovation, real-world impact, and hands-on engineering, youll be in the right place - and wed 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.
