REGENT is building an in-house training simulator for its Seaglider, signaling that it is moving from prototype to certified production and is setting up crew training and regulatory-grade simulation as a core function of a new passenger aircraft-like product.
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.
A Seaglider simulation has to hold up in two places: on the test bench, where real actuators and avionics respond to simulated conditions, and in the training simulator, where crews need the Seaglider to respond as it would on the water and in flight. As a Senior Modeling & Simulation Engineer, HIL & Training Simulator Systems at REGENT, you’ll own the work that makes our vehicle models useful in both settings.
Hardware-in-the-loop: Build and run the test benches that exercise actuators, avionics, and vehicle systems against our real-time simulation.
Training simulator program: Get REGENT's own compiled vehicle dynamics and control models running correctly inside the crew training simulator our outside simulator and curriculum partners are building, and own that integration end to end.
Validation: Compare simulated behavior to what the real hardware and vehicle actually do, and close the gap when they disagree.
This role sits at the intersection of hardware, real-time simulation and modeling, and cross-organization requirements work, on a program that's moving into building real training hardware.
If you’ve owned a HIL bench or a hardware program from end to end and are excited to bring that hands-on experience to testing a new class of vehicle and helping crews learn to operate it, we’d love to meet you!
Design, build, and operate hardware-in-the-loop (HIL) test benches for multiple REGENT programs. Translate test requirements into bench architectures, map I/O between the simulation and real actuators, avionics, and other vehicle hardware, and configure models for fixed-step execution and code generation. Bring each bench online, verify signal mapping and timing, and adapt the setup as hardware and test needs evolve.
Own the integration of REGENT’s compiled vehicle dynamics and controller models into the crew training simulator. Work directly with the simulator vendor to define and implement interfaces for I/O, timing, and environmental effects. Debug the models on the vendor’s platform and use REGENT vehicle test data to verify that the integrated simulator reproduces the Seaglider responses crews need to train on.
Validate simulated behavior against measured data from bench, hardware, and vehicle testing. Identify where simulated and measured responses diverge, then design targeted checks to isolate the cause. Drive the changes needed in the model, interface, or test setup and rerun the relevant tests to verify that the discrepancy is resolved.
Drive technical coordination across internal teams and external partners. Work with controls, avionics, and test engineers, hardware and software vendors, and crew training partners to agree on interface requirements and plan integration and verification work. Surface conflicting assumptions and schedule dependencies early, and document interface decisions, bench configurations, and test results so others can reproduce the setup and build on it.
Demonstrated experience owning the design, build, and operation of hardware-in-the-loop (HIL) or hardware test benches for complex vehicle systems in aerospace, automotive, maritime, or a comparable industry. Given a test requirement, you can choose a bench architecture, map the I/O, and integrate hardware that meets real-time timing constraints.
Hands-on ownership of model or software integration onto a third-party platform. You work through the interface details yourself, debug issues on the target hardware, and verify that the model behaves as intended once integrated.
The ability to spot and resolve mismatched assumptions at system interfaces. You catch when your team and a vendor expect an interface to behave differently, or when a model behaves differently on target hardware than it does on your desktop. You work with the engineers involved to pin down the cause, agree on the fix, and verify it.
Experience validating simulation models against hardware or vehicle test data. When results diverge, you dig into the data, design checks to isolate the cause, and verify that the fix brings the simulation and measured behavior into closer agreement.
A technical foundation in real-time modeling and simulation, including hands-on experience with MATLAB/Simulink and real-time or HIL tools such as Concurrent Real-Time, dSPACE, Speedgoat, or equivalent platforms, along with the ability to read and debug C/C++.
A habit of documenting as you build, including capturing bench configurations, interface decisions, and verification results so a teammate or external partner can reproduce your setup and troubleshoot it.
Experience with certified or regulator-facing training simulators, automotive driver-assistance (ADAS) X-in-the-loop or HIL programs, spacecraft or aerospace avionics test benches, or statistical methods for validating simulations against test data is a plus.

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. 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.
