Axiom Space is building the world's first commercial space station - Axiom Station. Serving as a cornerstone for sustained human presence in space, this next-generation orbital platform fosters groundbreaking innovation and research in microgravity, and cultivates the vibrant, global space economy of tomorrow. Today, driven by the vision of leading humanity's journey off planet, Axiom Space is the principal provider of commercial human spaceflight services to the International Space Station and developer of advanced spacesuits for the Moon and low-Earth orbit. Axiom Space is building era-defining space infrastructure that drives exploration and fuels a vibrant space economy that will empower our civilization to transcend Earth for the benefit of every human, everywhere. Axiom Space fosters a work environment inclusive of all perspectives. We are the pioneers of commercial space, leading the transformation of low-Earth orbit into a global space marketplace. Our mission-driven team is seeking a bold and dynamic GNC Engineer who is fueled by high ownership, execution horsepower, growth mindset, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond. POSITION SUMMARY We are looking for a resilient, high-energy, experienced GNC Engineer with experience developing aerospace vehicle simulation models. The engineer will work in fast paced environment to contribute to the development of GNC simulation development and analysis across the program lifecycle for Axiom Space's modules. The successful engineer will work well across multi-disciplinary teams and use a system level understanding when implementing their design. The role requires strong technical background, organizational time management and adept communication skills. Will be based onsite at our Space Station Development Facility (SSDF). KEY DUTIES & RESPONSIBILITIES Design, analyze, and implement GNC algorithms & simulations for aerospace vehicles. Maintain and develop analysis tools, regression test scenarios, Monte Carlo framework and simulation architecture. Perform 6‑DOF modeling, simulation, and performance analysis to evaluate system behavior under nominal and off‑nominal conditions Build high‑fidelity dynamic models of vehicles, sensors, actuators, and environmental models. Conduct Monte Carlo analyses and sensitivity studies to validate robustness and reliability. Validate simulation models against test data and engineering expectations. Use programming languages including C/C++, python, and Matlab (or similar) to develop simulations. Collaborate with embedded software teams to integrate, test, and verify GNC functionality on hardware‑in‑the‑loop (HIL) systems. Support development of requirements, interface definitions, and verification plans for flight software. Plan and execute verification and validation activities, including unit tests, SIL/HIL testing, and integrated system tests. Analyze flight test or mission data to assess GNC performance and identify areas for improvement. Support troubleshooting and root‑cause analysis for anomalies observed during testing or operations. Work with hardware teams to define performance requirements and ensure compatibility with GNC architecture. Contribute to system‑level design reviews, requirements development, and architecture decisions. Collaborate with propulsion, avionics, structures, and mission operations teams to ensure GNC solutions align with overall vehicle design. Provide technical leadership on sub‑projects, mentor junior engineers, and support design trade studies. Prepare technical reports, design documentation, test plans, and analysis summaries for internal and external stakeholders. Present findings at design reviews, customer meetings, and cross‑disciplinary engineering forums. Ensure compliance with aerospace standards, safety requirements, and certification processes. Communicating project progress, status, and potential issues to stakeholders and leadership Implementing and maintaining agile project management methodologies throughout the project lifecycle Perform additional job duties as assigned
