Axiom Space is building for beyond, guided by the vision of a thriving home in space that benefits every human, everywhere. The leading provider of human spaceflight services and developer of human-rated space infrastructure, Axiom Space operates end-to-end missions to the International Space Station today while developing its successor, Axiom Station – a permanent commercial destination in low-Earth orbit that will sustain human growth off the planet and bring untold benefits back home.

Axiom Space fosters a diverse 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 Modeling & Simulation Engineer - Electrical Power who is fueled by problem-solving, continuously curious, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.


  • Develop and implement simulation models for simulation of Axiom spacecraft with a focus on electrical power hardware and software for generation, storage, and distribution.
  • Implement model control logic by collaborating with hardware and flight software developers.
  • Discover and resolve design interface and integration issues wherever they exist.
  • Tune simulation models with high-fidelity analysis results or test data provided by hardware owners.
  • Create unit and integration tests to assess simulation model accuracy and performance.
  • Work with simulation users to create and execute tests for coupled flight software and simulation testing.
  • Analyze simulation results, create associated documentation, and present summaries to stakeholders.
  • The focus of this role is not software engineering. The Modeling and Simulation Engineer must be able to understand spacecraft hardware and control systems, including reading electrical diagrams and using electrical analysis tools, to resolve design interface & integration issues and to create accurate computer models.
