About The Position

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!

Requirements

• 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.

Nice To Haves

• 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

Responsibilities

• 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.

Benefits

• 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
