REGENT, North Kingstown, Rhode Island, us, 02852
Guidance, Navigation, and Control (GNC) Engineer
At REGENT, we’re on a mission to revolutionize regional transportation between coastal cities. We’re building the seaglider, a wing-in-ground-effect craft designed to travel just above the water’s surface, combining the speed of an airplane with the low operating costs of a boat. Seagliders will unlock fast, affordable, and sustainable coastal transit for passengers and cargo, connecting cities, islands, and communities. Backed by leading investors and powered by a team of passionate engineers, builders, and operators, we’re scaling from a breakthrough prototype to full production and building the team to make it happen. Role Overview 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 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 handle gusts, waves, and the unexpected. Through high-fidelity simulation, hardware-in-the-loop testing, and hands-on tuning during sea trials, you’ll turn 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 join a group of driven, collaborative engineers who solve complex technical challenges and aim to make an impact as a team. We hold a high bar for engineering rigor, move fast, think boldly, and rely on 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! 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 high-fidelity simulation environments (MATLAB/Simulink or custom frameworks) to design and validate GNC algorithms. Perform 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 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. What You'll Bring
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. Bonus Experience
Ph.D. or research experience in nonlinear, adaptive, robust, or hybrid control. Direct contribution to ARP4754A, DO-178C, or DO-254 certification artifacts. CFD-coupled control design or ground-effect / hydrofoil dynamics experience. Flight-test or sea-trial planning and execution Who We're Looking For
Collaborative Team Player: You believe that great things happen when teams work together. You communicate effectively and collaborate with engineers, stakeholders, and other cross-functional teams to align on goals and move projects forward. You bring people together, ensuring that everyone is on the same page and moving towards a shared vision. Creative Problem Solver: You thrive on tackling complex challenges and finding innovative solutions. Whether orchestrating seamless mode transitions, resolving nonlinear control issues, or fine-tuning state estimators in real-world sea conditions, you approach each problem with creativity and rigor. You’re able to address immediate needs while also planning for future scalability and efficiency. Adaptable & Agile: In a fast-paced startup environment, you quickly adapt to changing priorities and requirements. You approach challenges with a calm, resilient mindset, and know how to pivot and adjust your approach as needed, ensuring that progress continues without missing a beat. Innovative Mindset: You’re driven by curiosity and a passion for technology. You’re passionate about driving continuous improvement, embracing new technologies to enhance efficiency, quality, and team performance. What We Offer
Competitive compensation including a robust equity incentive plan. Comprehensive health, dental, and vision insurance - we cover 100% of your premiums. 401(k) with company matching, so you can plan for the future. Generous flexible time off, paid parental leave, and company-wide holiday breaks. Relocation packages available for those moving to join our team. Daily, free catered lunches Learning & professional development opportunities If you’re ready to take on an exciting challenge, grow with us, and make a lasting impact, we want to hear from you.
Even if you don’t meet every requirement, but you see yourself contributing to our mission, we encourage you to apply. We value diverse skillsets and experiences and believe in the potential of passionate individuals to make a big impact. Equal Opportunity Employer
