Propulsion Senior Engineer – Pressure & Fluid Systems Verified today
About Axiom Space
Axiom Space is building the world's first commercial space station - Axiom Station. This next-generation orbital platform enables groundbreaking research in microgravity and supports sustained human presence in low-Earth orbit.
The Role
You will own the end-to-end technical execution of a bipropellant feed system from requirements definition through design, build, integration, test, and flight readiness. You will lead cross-functional teams and suppliers to deliver to aggressive cost and schedule targets while maintaining safety and configuration discipline.
Key Responsibilities
- Own end-to-end technical execution of spacecraft pressure control and fluid systems, including COPVs, flow control devices (valves, regulators, manifolds, filters) from requirements through design, build, integration, test and flight readiness
- Serve as subject matter expert in propellant feed system and pressurization system design, providing technical authority on system architecture, component selection, and interface definition
- Perform detailed modeling, analysis and simulation of fluid systems using tools such as GFSSP, ANSYS, and Fluent to evaluate system performance, fluid dynamics, thermal effects and transient behaviors
- Perform detailed sizing and selection of fluid system components, ensuring compatibility with performance, environmental, material and other requirements
- Define, plan, and execute system and component level tests including development, qualification and acceptance testing; anchor analytical models and validate simulations against test data
- Lead and participate in design and gate reviews, trade studies and subassembly integration activities; ensure compliance with system requirements and program milestones
- Coordinate and manage technical requirements and design certification activities with external vendors and suppliers
- Define and control functional and physical interfaces between fluid/pressure systems and vehicle level systems, collaborating with structures, thermal, avionics, and software teams
- Provide technical mentorship and guidance to less experienced engineers
- Deliver against safety, cost, and schedule targets
Required Qualifications
- Bachelor's degree in Aerospace, Mechanical or related Engineering discipline
- 7 or more years of relevant experience with demonstrated depth in pressure control and fluid systems design
- Significant hands-on experience with propellant feed system design, development, qualification and integration, including COPVs, valves, regulators, filters, manifolds and instrumentation
- Expertise in fluid dynamics, thermodynamics and heat transfer with demonstrated application to propulsion systems
- Experience with oxygen compatibility requirements and assessments
- Experience coordinating with external vendors on technical requirements, design verification, cost and schedule performance
- 3D modeling software experience; SolidWorks preferred
Preferred Qualifications
- Advanced degree in engineering or related field
Requirements
- Must be able to complete a U.S. government background investigation
- Proof of U.S. Citizenship or U.S. Permanent Residency is required
- Must be willing to work evenings and weekends as needed to meet critical project milestones
Work Environment
Generally an office environment, but may involve inside or outside work depending on the task. Work may involve sitting or standing for extended periods (90% of the time). May require lifting and carrying up to 25 lbs. (5% of the time).
