Job description

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 Simulation Interface Development 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 Simulation Interface Development Engineer to work with team members to develop a simulation interface system for our avionics and software test simulator. This simulation interface system will provide the link between the spacecraft avionics and simulations of the other vehicle subsystems to provide for closed‑loop operation and testing of the avionics system. The simulations will need to interface with the avionics hardware through numerous physical I/O channels. The required simulation interface system will provide the data paths between the various physical avionics I/O channels and the simulation server.

Key Duties & Responsibilities

• Collaborate with avionics hardware, flight software, and subsystem developers to establish command and measurement signal characteristics between the avionics system and other spacecraft subsystems.
• Identify the appropriate digital, analog, and other control and data acquisition components for the simulation interface system to communicate with the avionics system.
• Develop software for signal control and to communicate commands and measurements between the avionics system and the subsystem simulations.
• Install, integrate, and wire the digital, analog, and other signal components.
• Integrate and test the simulation interface system with the avionics system and simulation system for end‑to‑end functionality.
• Follow disciplined engineering test, configuration control, documentation, and management processes.
• Prepare technical documentation, including the electrical schematics/wiring diagrams and software design diagrams.
• Prepare design review presentations for peers, management, and external customers and partners.
• Perform other duties as assigned.

Qualifications

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required.
