Senior Full Stack Software Engineer Jobs in Westerly, RI

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.

As an Embedded Systems Software Engineer, you’ll play a role in developing and certifying our Seaglider product family. You’ll contribute to embedded software development, simulation testing, and hands-on electronics work, helping ensure our platform stays reliable, testable, and ready to evolve.

From managing real-time software and hardware-in-the-loop (HIL) testing to wiring up harnesses and spinning up GUIs, your work will directly impact how we prototype, validate, and push the boundaries of our tech. You’ll also collaborate closely with our controls, avionics, and modeling teams to ensure a smooth path from concept to demo - both on the bench and at sea. 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!

• Contribute to Seaglider product family embedded software stack: Develop, debug, and maintain the real-time software that runs on our Seaglider product family, from microcontroller code to Linux-based applications.

• Support test environment development and testing: Contribute towards development of the SIL and HIL test environment for verification of controls software. This will include coordinating with multiple disciplinary teams.

• Manage COTS electronics & harnessing: Set up and maintain the electronics ecosystem - from sensors and servos to single-board computers, harnesses, and breakout boards.

• Improve developer tools and processes: Automate build systems, streamline deployment pipelines, and build tooling to facilitate maintenance and certification.

• Prototype and field-test: Be a key part of the sea trials team - monitoring operation, running diagnostics, troubleshooting in the field, and reliably showing off our latest and greatest Seaglider capabilities.

• Demonstrated experience writing C++ for embedded systems - whether on Linux, RTOS, or bare metal

• Strong hands-on experience with microcontrollers and common embedded interfaces (Serial, SPI, CAN, PWM, ADCs, DIO, etc.)

• Ability to read, interpret, and contribute to wiring diagrams and electrical schematics

• Comfortable scripting with Python, MATLAB, or similar languages

• Experience with LabVIEW or Simulink for DAQ and HIL systems

• Familiarity with actuation systems like servo motors

• Field-testing experience and a knack for troubleshooting electronics in real-world environments

• Experience building safety-critical applications

• Familiarity with aerospace or automotive standards like DO-178C or ISO 26262

• 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. 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.

• 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.
