Our mission-driven team is seeking a bold and dynamic Lead – Software Engineer, Simulation 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

Axiom Space seeks a resilient, high‑energy Lead Software Engineer to spearhead development of a high‑fidelity simulation environment for a commercial space station. This platform models complex vehicle systems and hardware behavior across multiple physical domains, supporting engineering analysis, flight software verification, and mission operator training. The role blends physics‑based modeling with large‑scale simulation platform engineering to deliver robust, scalable capabilities. The ideal candidate can architect simulation frameworks, implement models and features hands‑on, and guide technical direction. Success requires aligning multidisciplinary stakeholders while driving high‑impact simulation development in a fast‑moving environment.

KEY DUTIES & RESPONSIBILITIES

• Lead technical direction, feature planning, and cross‑team coordination for simulation development.

• Develop and maintain physics‑based models of a spacecraft across multiple domains including mechanics, thermodynamics, fluids, and electrical.

• Represent system states and interactions across integrated subsystems.

• Validate models against test data and engineering expectations.

• Maintain and evolve real‑time and faster‑than‑real‑time simulation platforms for multiple mission use cases.

• Manage deterministic single‑thread CPU environments and multi‑threaded or GPU‑accelerated execution modes.

• Ensure deterministic, repeatable simulation behavior across configurations.

• Define and implement external interfaces, runtime APIs, and internal simulation tooling.

• Build and maintain CI/CD pipelines for simulation builds, testing, and deployment.

• Manage containerized development and runtime environments, including image registries and reproducible build systems.

• Maintain cloud (AWS) and on‑premise compute infrastructure to support large‑scale simulation workloads.

• Perform vehicle‑level analyses and trade studies using simulation outputs.

• Develop Python‑based configuration, post‑processing, and visualization tools.

• Mentor engineers, review designs and code, and troubleshoot complex system‑level issues.

• Communicate progress, risks, and status to stakeholders while supporting agile project execution.

• Perform additional job duties as assigned.
