About the role

Original posting from Apex Technology Inc via Ashby

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. 

ABOUT THE ROLE

Apex is seeking a 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. You will also be one of the first chemical propulsion engineers 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.
  • Bachelor's degree in mechanical, propulsion, or other aerospace-related engineering discipline.
  • 3+ years of propulsion design and test experience
  • Experience with mono and bi-propellant chemical propulsion systems
  • Experience with handling and testing pressurized systems
  • 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 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
