Senior Software Engineer

Senior GNC Software Engineer | Autonomous Air SystemsLos Angeles Metropolitan Area, California$160,000 – $240,000 + Pre-IPO Equity + Relocation Assistance + Outstanding BenefitsU.S. Citizenship RequiredAre you a Senior GNC Software Engineer with experience developing Guidance, Navigation & Control software for autonomous aircraft, UAVs or advanced aerospace systems? Do you enjoy taking clean-sheet autonomous vehicles from concept through simulation, flight testing and operational deployment? Do you want to develop the autonomous flight software that determines mission success on next-generation aerospace platforms? If so, this opportunity may be the right next step for you.This organisation develops advanced autonomous aerospace systems that combine intelligent sensing, real-time decision making and high-performance flight technologies to solve some of the most demanding challenges in modern defence. Engineers work in small, multidisciplinary teams where software, autonomy and flight systems are developed together, giving every engineer genuine ownership from concept through operational deployment. From early architecture and algorithm development through integration, flight testing and mission deployment, you'll play a pivotal role in delivering technologies that move rapidly from simulation into operational capability.The Senior GNC Software Engineer will lead the development of Guidance, Navigation & Control software for advanced autonomous air systems, working closely with software, systems, flight controls and hardware teams throughout the complete engineering lifecycle.As the Senior GNC Software Engineer your responsibilities will includeDeveloping Guidance, Navigation & Control software for autonomous aircraft and advanced aerospace platformsDesigning flight control, guidance and autonomy algorithms using PX4, ArduPilot or comparable flight software frameworksIntegrating software onto embedded Linux platforms, real-time operating systems and flight hardwareSupporting simulation, Hardware-in-the-Loop (HIL), flight testing and operational deployment activitiesCollaborating with multidisciplinary engineering teams to optimise vehicle performance, autonomy and mission capabilityAs the Senior GNC Software Engineer you will bringExperience developing Guidance, Navigation & Control software for UAVs, autonomous aircraft, missiles or advanced aerospace systemsStrong C++ software engineering capability with experience developing embedded or real-time systemsUnderstanding of flight dynamics, control systems, autonomy and autonomous vehicle behaviourExperience with PX4, ArduPilot or similar autonomous flight software frameworksStrong technical problem-solving skills with experience integrating software, sensors and embedded flight hardwareThe Senior GNC Software Engineer will become one of the engineers shaping the future of autonomous aerospace capability, developing flight software that directly influences vehicle performance, mission success and operational effectiveness. Alongside meaningful pre-IPO equity, comprehensive relocation support and outstanding benefits, this role offers genuine technical ownership, exposure to cutting-edge autonomous technologies and a clear pathway towards Principal Engineer, Technical Fellow or Engineering Manager positions as the organisation continues to grow.All successful applicants will be contacted within two working days.
