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 Staff Flight Software Engineer, you’ll lead the development of safety-critical avionics software for REGENT’s seaglider. These vehicles operate hull-borne, foil-borne, and wing-borne - demanding flight software that is simultaneously innovative, robust, and certifiable. You’ll own software spanning real-time control, mode logic, sensor and actuator integration, health monitoring, and inter-processor communications, ensuring it performs flawlessly under the toughest conditions.
You’ll define the plans, processes, and evidence required for safety-critical software across teams and criticalities, and drive approvals with classification societies and flag/state authorities. Along the way, you’ll architect partitioned RTOS-based systems with strict timing and isolation standards, stand up certification-ready CI/CD pipelines, and lead requirement-based verification through SIL, HIL, and full-scale sea trials. Working across disciplines - controls, avionics, systems, and testing - you’ll help define the future of flight software for amphibious mobility.
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 the Software Certification Path: Lead the full software certification and assurance plan - spanning development, verification & validation, configuration, and quality - and guide staged reviews with class societies and regulators through approval.
Architect Robust Systems: Define partitioned RTOS architectures, including time and memory partitioning, inter-process communication, timing budgets, and health monitoring to ensure safety and reliability under all conditions.
Build and Review Flight Software: Establish interfaces and MISRA-style coding standards, design for determinism and fault tolerance, perform thorough code and design reviews, and directly implement or prototype critical avionics modules in C/C++.
Ensure Compliance with Rigor: Drive adherence to industry and regulatory standards across varying criticalities, maintaining requirements–design–test traceability, separation of roles, and compliance evidence at every stage.
Validate in Simulation and at Sea: Lead verification campaigns including robustness and fault-injection testing, requirements-based testing, MC/DC analysis, SIL/HIL on representative hardware, and structural coverage.
Qualify Tools and Methods: Select and qualify development and verification tools under DO-330, documenting constraints and mitigations to ensure compliance and reliability.
Manage External Software with Care: Govern SOUP and COTS acceptance, ensuring supplier evidence and mitigations meet safety-critical standards.
What You'll Bring
Extensive experience in safety-critical software development under DO-178C (ideally DAL A/B), with a proven track record leading SOI preparation and closure
Deep expertise in RTOS and partitioned systems, including scheduling, WCET/jitter analysis, inter-partition communication, and real-time health monitoring.
Proven C/C++ flight software excellence, with hands-on experience in concurrency, memory management, and numerical robustness — able to design, implement, and review production-grade code.
Fluency in CI/CD for safety-critical programs, ensuring artifact control, provenance, on-target coverage, and fully reproducible builds.
Strong systems mindset with ARP4754A grounding, skilled in requirements decomposition, interface definition, and hazard-driven design.
Exceptional communicator and technical writer, able to align diverse engineering teams and regulatory stakeholders around complex safety-critical systems.
Bonus Experience
Familiarity with advanced avionics architectures and standards, including DO-297/ARINC-653, hypervisor/IMA, DO-254, and DO-160 compliance
Hands-on experience with tool qualification and model-based methods, including DO-330, DO-331, and back-to-back testing for safety-critical workflows
Proficiency with safety middleware and fault-tolerant systems, including DDS, monitors, voters, and watchdog implementations
Expertise in verification and performance instrumentation, including MC/DC closure on target and timing analysis/profiling
Practical maritime and sea-trial experience, validating software performance in real-world operational conditions
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 it’s architecting partitioned RTOS systems, solving complex certification challenges, or ensuring deterministic real-time flight software, you tackle every problem with ingenuity and rigor. You balance solving today’s technical needs while designing for future scalability and reliability in autonomous systems.
Adaptable & Agile: In a dynamic, 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.
