Senior Chemical Propulsion Engineer

Apex is seeking a Senior Chemical Propulsion Engineer to join our closely integrated team, driving the development of our chemical propulsion systems to meet the requirements of our spacecraft bus. You will have the opportunity to approach this from a clean-sheet design, guiding propulsion system architecture, integration, and testing to ensure optimal performance.

You will also be the first chemical propulsion engineer at Apex Space, and will help build our chemical propulsion capabilities, team, and infrastructure from the ground up.

- Design and build propulsion infrastructure and test facilities

specifications, and maintain Technical Performance Metrics (TPMs)

- Develop qualification and acceptance test plans and support said

- Collaborate with cross-functional teams to integrate propulsion

systems with other subsystems (e.g., electrical, thermal, structure).

- Troubleshoot anomalies that arise during manufacturing, lead

investigation efforts, and ensure design for manufacturability (DFM)

- Directly interface with customer/supplier relationships, conduct

analyses, and provide support (either virtual or onsite) as necessary.

- Contribute to proposals and business development efforts as needed.

- U.S. Person status is required as this position needs to access export controlled data.

- Bachelor's degree in mechanical, propulsion, or other aerospace-related engineering discipline.

- Experience with mono and bi-propellant chemical propulsion systems

- Demonstrated history of designing fluidic systems, fluid system

instrumentation, and control components (i.e. tanks, regulators, pressure transducers, thermocouples, solenoid valves, etc.)

- Working knowledge for manufacturing in a clean environment and following AS9100 protocols

- Master's or Ph.D in mechanical, propulsion, or other aerospace-related engineering discipline

- Experience leading an hot-fire test campaigns (power and fluid delivery systems for ground test, data acquisition systems, thrust stands, and plume diagnostics).
