Guidance, Navigation, and Control (GNC) Engineer
Job Summary
Job Description
REGENT is revolutionizing regional transportation with seagliders, a new category of craft that combines airplane speed with boat operating costs. As a Controls Engineer, you will develop the seaglider's flight-control logic to ensure stability, responsiveness, and safety during transitions between different flight modes. Your work will involve coordinating aerodynamic and hydrodynamic surfaces into an intelligent system to handle disturbances like gusts and waves. Through simulation, hardware-in-the-loop testing, and sea trials, you will transform control theory into a certifiable mobility solution. Joining the Software Team, you will collaborate with talented engineers to solve complex technical challenges and push boundaries, making a real-world impact.
Must have:
- Design and flight-test control systems for complex vehicles.
- Strong theoretical foundation in control theory.
- Proven design of real-world control systems.
- Experience with MATLAB/Simulink for control design.
- Demonstrated safety and quality mindset.
Good to have:
- Ph.D. or research in nonlinear, adaptive, or robust control.
- Experience with ARP4754A, DO-178C, or DO-254.
- CFD-coupled control design.
- Ground-effect or hydrofoil dynamics experience.
- Flight-test or sea-trial planning and execution.
Perks:
- Competitive compensation with equity.
- 100% covered health, dental, and vision insurance.
- 401(k) with company matching.

Job Details
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.
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 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 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.
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 you're 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, ever-evolving 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 and methodologies 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
