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 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!

• 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.

• 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…
