Modeling and Simulation 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.

We are seeking a Senior Modeling and Simulation Engineer to build and own the simulation environments that underpin seaglider design, controls/autonomy development, software integration, and training. You will develop and maintain vehicle, environment, sensor, and actuator models and integrate them into a coherent, versioned simulation stack. This stack will be used across the company for design decisions, regression testing, and rehearsals.

The role blends deep MATLAB/Simulink and physics-based modeling with strong software engineering, validation discipline, and a focus on reliable, repeatable infrastructure.

• Lead the design, development, and maintenance of simulation environments that enable multiple engineers to collaborate seamlessly, working in parallel and integrating subsystems.
• Develop and fine-tune simulation models using MATLAB/Simulink to ensure they precisely represent the behavior of complex systems.
• Work closely with cross-disciplinary teams to integrate real-world system and vehicle dynamics data into the simulation environment, enhancing its accuracy and effectiveness.
• Run and refine testing cycles such as software-in-the-loop, processor-in-the-loop, and hardware-in-the-loop to validate models and simulation environments.
• Analyze sea trial test data and leverage it to fine-tune and improve model accuracy and system reliability.
• Ensure that the simulation environment is scalable, robust, and ready to handle large, complex simulations with ease.
• Keep up with the latest trends and technologies in modeling and simulation, and bring fresh ideas and techniques to continually elevate the simulation environment.

• Proven experience in software engineering, computer science, or a related field.
• Demonstrated success and professional experience in modeling and simulation, especially with MATLAB/Simulink integration and testing.
• Expertise in using MATLAB/Simulink and the Math Works toolchain, with some experience in C/C++.
• Hands‑on experience designing and building simulation environments that enable collaboration across multiple engineers working on different subsystems.
• A collaborative mindset, with experience integrating physical system and vehicle dynamics data into simulations across disciplines.
• Proven ability to validate models against real‑world test data and refine them to enhance performance.
• Demonstrated experience with software-in-the-loop, processor-in-the-loop, and hardware-in-the-loop testing (or a desire to learn quickly on the job).
• Bonus points: Experience with simulation tools for DO‑178C verification and validation (if you’re familiar, we’d love to hear about it).

• 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 it’s optimizing data pipelines, solving integration hurdles, or improving automation workflows, you approach every problem with creativity and determination. You’re…
