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 Senior GNC Engineer with experience designing control systems for flight vehicles. The engineer will work in fast paced environment to contribute to the development of control systems 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
