equivalent ArduPilotvehicle platforms• SITL/HITL: Hands-on experience configuring, running, and troubleshooting ArduPilotSoftware-in-the-Loop (SITL) and Hardware-in-the-Loop (HITL/HIL) testingenvironments• Automated Testing: Experience developing automated simulation tests, regression tests,and validation workflows for autonomous vehicle software• MAVLink: Understanding of telemetry, vehicle commands, parameters, missionexecution, and communication protocols• Vehicle Control: Understanding of actuators, navigation, operating modes, andsafety/failsafe behavior• Linux: Experience developing and troubleshooting software on Linux-based systems• Version Control: Experience using Git, GitLab, or equivalent source-control platforms• Project Management: Familiarity with Jira or similar issue-tracking systems• AI-Assisted Development: Familiarity with generative AI coding tools such as Cursor,OpenAI Codex, or similar• Hardware Integration: Experience integrating software with sensors, embeddedhardware, or external control systemsPreferred Qualifications• ATAK/WinTAK plugin development and integration• TAK ecosystem experience, including Cursor on Target (CoT)• Autonomous boat/USV development and on-water testing experience• Marine propulsion, throttle, gear shifting, steering, and actuator control• CAN bus, serial communications, and marine engine integration• GNSS, IMUs, compass/heading sensors, and navigation systems• NVIDIA Jetson and other embedded computing platforms• TCP/IP, UDP, and remote vehicle communication systems• Docker, GitLab CI/CD, and automated deployment workflows• Experience with robotics, autonomous vehicles, or defense systemsKey Responsibilities• Develop, modify, and maintain ArduPilot/ArduRover C++ source code for unmannedsurface vessels• Implement vessel-specific control functionality, including throttle, steering, gear shifting,and engine control• Develop and maintain ArduPilot SITL/HITL simulation and testing environments• Create automated simulation and regression tests to validate vehicle behavior andsoftware changes• Develop and test vehicle safety interlocks, operating modes, and failsafe functionality• Integrate MAVLink telemetry, vehicle commands, parameters, and autonomous missionexecution• Support ArduPilot integration with ATAK/WinTAK and third-partycommand-and-control systems• Integrate navigation sensors, propulsion interfaces, and other onboard vehicle hardware• Troubleshoot autonomous control issues during development, simulation, hardwaretesting, and on-water operations• Collaborate with software, electrical, mechanical, and networking engineers• Participate in code reviews, software testing, and release processes• Maintain source code, technical documentation, and development tasks using GitLab andJira• Use AI-assisted coding tools to improve development efficiency while validatinggenerated code through appropriate testingIdeal Candidate• Has demonstrated experience working directly with ArduPilot source code rather thanonly configuring or operating ArduPilot systems• Enjoys developing and troubleshooting autonomous vehicle software• Comfortable working with simulation environments and physical vehicle hardware• Understands the importance of testing vehicle-control functionality before fielddeployment• Capable of independently implementing assigned software features with appropriatetechnical guidance and code review• Interested in autonomous maritime systems, robotics, and real-world engineeringchallenges• Comfortable working in a fast-paced environment with evolving requirementsAdditional Requirements• Ability to work hands-on with embedded hardware, sensors, and vehicle-control systems• Willingness to participate in laboratory, dockside, and on-water testing• Willingness to travel occasionally for field testing and integration activities• Strong problem-solving and troubleshooting skills• Effective communication, teamwork, and technical documentation skillsPhysical Requirements and Working EnvironmentThis role combines office and laboratory work with hands-on vessel integration and outdoor testing.• Ability to manually lift and carry equipment and materials weighing up to 50 pounds.• Ability to crawl, kneel, crouch, bend, climb, and work in confined or awkward spaces while installing, inspecting, and servicing equipment on and around vessels.• Ability to safely board and move around boats, docks, and uneven or wet surfaces.• Comfortable working outdoors and in marine environments, including dockside activities and on-water testing.• Occasional travel and schedule flexibility may be required to support trials and demonstrations.Background CheckThis position will require
