Modeling & Simulation Intern (Summer)

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

REGENT's Modeling and Simulation team sits at the intersection between controls, performance, and test — the place where flight dynamics, hydrodynamics, and vehicle data all come together to answer one question: how does the Seaglider actually behave, and how do we make the model match reality? As our intern on this team, you'll work across multiple Seaglider programs at very different stages of life — from envelope expansion on a vehicle that's already flying, to ramping up on-water testing on another, to helping build modeling and simulation infrastructure from scratch on our newest program. Your day-to-day will center on building, running, and refining simulations in MATLAB/Simulink, and helping turn real test data into sharper, more trustworthy models.

This is a role for someone who wants the wide view rather than a narrow lane. Instead of specializing early in one technical corner, you'll get exposure to flight dynamics, hydrodynamics, and controls all at once, and you'll see how a model evolves differently depending on whether a program is just getting started or already pushing its performance envelope. You'll be working alongside engineers who care deeply about getting the model right and who are genuinely invested in helping you build real technical depth along the way.

If you're someone who gets energized by breadth, by ambiguity with real structure behind it, and by the idea of helping shape how REGENT understands its own vehicles, we'd love to have you on the team.

What You'll Do

- Build and Run Simulations: You'll work hands-on in MATLAB/Simulink to build, run, and refine simulations that model how our Seagliders actually perform. This is the core toolset the team relies on every day, and you'll use it across more than one program.
- Turn Test Data Into Better Models: You'll help translate real flight and on-water test data into model improvements, closing the loop between what we predict and what actually happens. Your work will directly sharpen the accuracy of the models the rest of the team relies on.
- Support Envelope Expansion: You'll contribute to analysis supporting envelope expansion on an established Seaglider program, helping define and refine performance limits based on real test results.
- Help Ramp Up On-Water Testing: On a program moving into a new testing phase, you'll help build out the modeling and simulation support needed to keep pace with an accelerating on-water test campaign.
- Stand Up Modeling From the Ground Up: On our newest program, you'll get the rare opportunity to help build modeling and simulation work from first principles, shaping foundational models rather than just maintaining existing ones.
- Contribute to Verification and Validation: Depending on where your interests take you, you may help write simulation-driven test sequences that support software verification and validation across the vehicle.
- Collaborate Across Disciplines: You'll pull in inputs from controls, performance, and test teams rather than working in isolation, giving you a genuinely integrative view of how the whole vehicle comes together.

What You'll Bring

- MATLAB and Simulink Fluency: You're comfortable building and running simulations in MATLAB/Simulink without needing hand-holding on the basics. This is the team's primary tool, and you'll be using it from day one.
- Linux Comfort: You're at ease working in a Linux environment, able to navigate it independently as part of your daily workflow.
- A Flight Dynamics or Hydrodynamics Foundation: Some grounding in flight dynamics and/or hydrodynamics helps you interpret test and simulation results meaningfully, especially when the team is working to set performance limits on an existing vehicle.
- Control Systems Exposure: Understanding how controllers and plant models interact will help you make sense of the team's model architecture more quickly.
- Independent Problem-Solving: You're able to take direction and then run with it, working through simulations and analysis without needing every step spelled out.
- Curiosity Across Domains: You're genuinely interested in how flight dynamics, hydrodynamics, and controls fit together, rather than wanting to wall yourself off into just one of them.

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 resolving installation challenges, debugging elusive electrical issues, or adapting on the fly during integration and test, you bring a practical, inventive mindset to every problem. You don't just patch issues - you improve processes, anticipate downstream impacts, and help turn one-off fixes into scalable solutions that raise the bar for future builds.
- 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.
