Senior Mission Software Engineer

At REGENT, we're on a mission to revolutionize regional transportation between coastal cities. We're looking for a Senior Mission Software Engineer to drive development and integration of the Seaglider's vehicle-level software: the system that ties guidance, navigation, control, communications, and health monitoring together. You'll build and integrate the software for our first production Seagliders — spanning multiple avionics units, high-rate control loops, and mission logic — and help take our platform from prototype to production-ready, with major milestones ahead in hardware integration, sea trials, and autonomy.

Responsibilities

Build the vehicle software framework and evolve interfaces between subsystems; Integrate software on real vehicles including hardware bring-up, sensor drivers, and tuning; Build for reliability with telemetry, logging, fault management, fail-safe behavior, test harnesses, and software update with rollback; Support test operations by owning the software integration schedule and debugging issues in the field; Partner with autonomy to define and build the vehicle-side interface; Mentor earlier career engineers and uphold coding guidelines and review practices

Requirements

Experience developing software for vehicles or robots, ideally in aerospace (avionics, UAV, eVTOL) or automotive (ADAS, autonomous vehicles); Strong C++ for complex systems: memory management, multi-threading, performance in embedded or near-embedded environments; Real-time experience (RTOS or real-time frameworks) and software that talks directly to sensors and actuators; A track record of integrating software on actual vehicles - bring-up, driver debugging, tuning in test; Systems programming depth: networking (UDP/TCP, CAN), threading, IPC, and long-duration robustness; Familiarity with safety-critical principles (fail-safe states, watchdogs, redundancy); Collaborative team player who works across software, controls, perception, systems, and hardware teams; Creative problem solver who digs into software, logs, interfaces, hardware, and test data; Adaptable and agile in a fast-moving startup; Ownership mindset with a bias toward shipping, testing, and learning; Broad technical curiosity across different parts of the software stack

Nice to have

Experience under design assurance obligations (DO-178C or comparable); Avionics protocols (ARINC 429, CAN); Implemented Kalman filters or control loops; Embedded CI/DevOps; GPU and high-rate data processing; Prior startup experience

Benefits

Competitive compensation including robust equity incentive plan; Comprehensive health, dental, and vision insurance with 100% of premiums covered; 401(k) with company matching; Generous flexible time off, paid parental leave, and company-wide holiday breaks; Relocation packages; Daily free catered lunches; Learning and professional development opportunities
