Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.
For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.
Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.
We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.
Apex is seeking a seasoned Senior Propulsion Engineer (Chemical) 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.
Responsibilities:
Design, build, and test chemical propulsion systems
Design and build propulsion infrastructure and test facilities
Design propulsion system architecture, develop product
specifications, and maintain Technical Performance Metrics (TPMs)
Develop qualification and acceptance test plans and support said
testing
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)
approaches are followed during all stages of development
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.
Requirements:
U.S. Person status is required as this position needs to access export controlled data.

Demonstrated history of designing fluidic systems, fluid system
instrumentation, and control components (i.e. tanks, regulators, pressure transducers, thermocouples, solenoid valves, etc.)
Experience with CAD software (NX, SolidWorks)
Working knowledge for manufacturing in a clean environment and following AS9100 protocols
Preferred Qualifications:
Master's or Ph.D in mechanical, propulsion, or other aerospace-related engineering discipline
Experience operating leak, burst, proof test facilities
Experience leading an hot-fire test campaigns (power and fluid delivery systems for ground test, data acquisition systems, thrust stands, and plume diagnostics).
Experience with chemical propulsion operations in space
