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 Life Support Systems (LSS) Thermal 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 LSS Thermal Engineer, who will primarily be responsible for aiding Axiom’s Environmental Control & Life Support Systems (or ECLSS) team with the development, maturation, and operation of thermal-fluid spaceflight hardware to support the Axiom Station. This role will develop, iterate, and mature thermal system designs for low earth orbit environments by owning product delivery timelines through concept, design, fabrication, assembly, launch, on-orbit operation, and on-orbit services. This position reports to Life Support Systems Manager.  This role is onsite and will be based at our Space Station Development Facility (SSDF).

KEY DUTIES & RESPONSIBILITIES

• Define and create modern space station thermal-fluid system standards and practices, driving Axiom to the forefront of station production and operation

• Own design, development, integration, and verification of thermal-fluid hardware for crewed spaceflight applications

• Lead design and production reviews internally and externally with suppliers and customers

• Collaborate with cross-functional teams (Stress, avionics, manufacturing) to ensure proper integration and meet mission requirements

• Lead thermal system trade studies and architecture decisions balancing performance, reliability, manufacturability, operability, schedule, and cost

• Perform thermal-fluid system sizing and analysis for thermal-fluid hardware (radiators, pumps, heat exchangers, cold plates, accumulators, valves, regulators, lines, manifolds, and thermal interfaces)

• Establish an efficient product lifecycle starting in the supply chain all the way through final integration that balances cost, complexity, and quality

• Generate and/or review CAD models engineering schematics, drawings, analysis, assessments, and procedures for components, assemblies, and integrated assembly

• Develop and review thermal mathematical models and simulations to predict steady-state and transient thermal performance across all mission phases

• Conduct thermal-fluid analyses including pressure drop calculations, flow balancing, heat transfer assessments, fluid network modeling, and system performance characterization

• Validate designs by analysis or test, building development articles as needed

• Support the manufacturing and assembly of hardware in the facility and through on-orbit operation

• 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
