Modeling and Simulation Engineer

About the role

Axiom Space is a human space exploration company building era‑defining space infrastructure and delivering technology‑driven solutions that empower civilization to transcend Earth. The company is pioneering a next‑generation orbital settlement and provides commercial human spaceflight services and advanced spacesuits for the Moon and beyond. The Modeling and Simulation Engineer will support the EVA SE&I team by developing modeling and simulation assets that assess EVA spacesuit performance for analysis and verification purposes.

Responsibilities

• Develop high‑fidelity spacesuit fluid, thermal, and electrical simulation math models using existing frameworks and nodal analysis methods (NASA’s Trick simulation and GUNNS software).
• Collaborate with spacesuit subsystem teams to ensure models accurately reflect design and operational details of life‑support components.
• Debug, test, verify, and validate model packages 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 ensure proper simulation execution.
• Apply systems engineering principles to the development and documentation of the simulation framework and constituent models.
• Use the simulation to evaluate spacesuit performance, conduct trade studies, and assess design changes.
• Use simulation to verify system requirements.
• Support other Systems Engineering and Integration functions as needed.
• Communicate project progress, status, and potential issues to stakeholders and leadership.
• Implement and maintain agile project‑management methodologies throughout the project lifecycle.
• Perform additional duties as assigned.

Qualifications

• Experience designing and implementing or modeling and simulating fluid, thermal, or electrical systems.
• Experience performing simulation credibility assessments.
• 2+ years of programming experience with systems‑level languages such as C/C++ and/or Python.
• Experience performing simulation software verification and validation activities.
• Strong oral and written communication skills; ability to present technical data to both technical and non‑technical audiences.
• Track record of delivering results in ambiguous, fast‑moving environments.
• Demonstrated organization skills to meet tight deadlines with high‑quality results.
• Level II: Bachelor’s degree in Engineering or related technical field (ABET‑accredited preferred) and 2–6 years of experience, or equivalent combination.
• Level III: Bachelor’s degree in Engineering or related technical field (ABET‑accredited preferred) and 4–9 years of experience, or equivalent combination.
• Level IV: Master’s degree or Ph.D. in Engineering (preferred) and 7–12 years of experience, or equivalent combination.
• Level V: Master’s degree or Ph.D. in Engineering (preferred) and 10–16 years of experience, or equivalent combination.

Skills

• Passion for space and Axiom’s mission.
• Entrepreneurial, growth‑mindset.
• High emotional intelligence and ability to collaborate across teams.
• Tech‑solutioning using systems and tools to move smarter and faster.

Competencies

• Accountability
• Technical Rigor
• Execution Discipline
• Pride of Delivery
