Job description

Axiom Space is a human space exploration company, building era-defining space infrastructure and delivering technology-driven solutions that will empower civilization to transcend Earth. Beginning with Axiom Station, successor to the International Space Station, the company is pioneering a next-generation orbital settlement that will foster groundbreaking innovation and research in microgravity and drive the global space economy of tomorrow. Today, guided by the vision of leading humanity's expansion off planet, Axiom Space is the principal provider of commercial human spaceflight services and developer of advanced spacesuits for the Moon and beyond. For more information about Axiom Space, visit www.axiomspace.com. 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 Modeling and Simulation Engineer who is fueled by high accountability, execution horsepower, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.

POSITION SUMMARY

Since Axiom Space is a very complex work environment, we are looking for a resilient, high-energy, experienced Modeling and Simulation Engineer to support the EVA SE&I team. The EVA SE&I Modeling and Simulation Engineer will develop the modeling and simulation assets that assess the performance of the EVA spacesuit for analysis and verification purposes.

KEY DUTIES & RESPONSIBILITIES

• Develop high-fidelity space suit fluid, thermal, and electrical simulation math models leveraging existing simulation frameworks and nodal analysis methods (NASA’s Trick simulation and GUNNS software).
• Collaborate with space suit subsystem teams to ensure models accurately reflect design and operational details of life support components.
• Ensure model packages are debugged, tested, verified, and validated with test data.
• Perform and document simulation verification and validation activities.
• Develop and implement methods for assessing simulation credibility including uncertainty characterization and results robustness/sensitivity analysis.
• Incorporate models into the larger simulation framework and work to ensure simulation runs appropriately.
• Apply systems engineering principles to the development and documentation of the simulation framework and constituent models.
• Use the simulation to evaluate spacesuit performance, perform trade studies, and assess design changes.
• Use simulation to perform verification of system requirements.
• Support other Systems Engineering and Integration functions as appropriate and needed.
• 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.
