You will build software spanning guidance and control, mission autonomy, and navigation while working closely with RPA pilots, GNC engineers, software platform engineers, simulation engineers, and command-and-control teams.\nThis is a hands-on role for an engineer who is comfortable owning difficult, cross-functional problems from initial design through integration and flight testing. You will directly influence how Hermeus aircraft navigate, execute missions, interact with operators, and progressively achieve higher levels of autonomy.\nThe ideal candidate combines strong modern C++ software-development skills with experience in autonomous or unmanned systems and a practical understanding of guidance, controls, and navigation.\nResponsibilities\nDevelop modern C++ software for flight autonomy, guidance, navigation, and control\n\nDesign and implement mission-autonomy behaviors and vehicle decision-making capabilities\n\nDevelop and integrate guidance and control loops for unmanned aircraft\n\nSupport the integration, evaluation, and validation of navigation sensors and navigation solutions\n\nIntegrate autonomy capabilities into existing aircraft software architectures and command-and-control systems\n\nDevelop automated test suites, simulation scenarios, and utilities to verify autonomy performance and expected behavior\n\nWork closely with GNC and simulation engineers to develop, test, and validate autonomy algorithms\n\nPartner with RPA pilots and flight-operations teams to define and execute the autonomy roadmap\n\nIntegrate autonomy software with vehicle systems, communications links, ground systems, and operator interfaces\n\nDiagnose and resolve complex problems spanning autonomy software, vehicle dynamics, navigation, simulation, and command-and-control interfaces\n\nParticipate in software-in-the-loop, hardware-in-the-loop, ground-test, and flight-test activities\n\nOwn technical problems from initial investigation through implementation, integration, testing, and operational use\n\nDrive solutions across multidisciplinary teams in environments where requirements and vehicle capabilities are rapidly evolving\n\nRequirements\nBachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, Robotics, or a related technical field\n\nStrong proficiency with modern C++, including experience developing production-quality software\n\nStrong general software-engineering fundamentals, including software architecture, debugging, testing, and performance-conscious development\n\nExperience developing software for unmanned aircraft, autonomous vehicles, robotics, spacecraft, or other autonomous systems\n\nExperience with guidance and control algorithms, control loops, trajectory generation, or vehicle guidance software\n\nExperience developing or integrating flight or mission-autonomy capabilities\n\nExperience developing or integrating navigation systems, sensors, or state-estimation solutions\n\nAbility to work effectively across software, GNC, simulation, systems, operations, and other engineering disciplines\n\nDemonstrated ability to independently identify technical problems and drive them through resolution\n\nExperience integrating complex software capabilities into larger vehicle or robotic-system architectures\n\nPreferred Skills and Experience\nExperience developing autonomy software for unmanned aerial systems or remotely piloted aircraft\n\nExperience with flight guidance, path planning, trajectory generation, control allocation, or vehicle control\n\nExperience with GNSS, INS, IMUs, air-data systems, sensor fusion, or other navigation technologies\n\nExperience integrating autonomy software with command-and-control systems\n\nFamiliarity with over-the-air communications, vehicle-to-ground protocols, telemetry, and command interfaces\n\nExperience with mission planning, contingency management, health monitoring, or autonomous decision-making\n\nExperience with Linux-based embedded or real-time software systems\n\nExperience with simulation, SIL, HIL, system-integration labs, ground testing, or flight testing\n\nExperience collaborating directly with pilots, operators, or flight-test teams\n\nAerospace, defense, robotics, autonomous vehicle, or spacecraft experience\n\nExperience working in a startup, rapid-prototyping, or highly iterative development
