Electric Propulsion Engineer (Early)

Apex Technology, Inc.•Los Angeles, CA

1d•Onsite

About The Position

Apex is seeking an Electric Propulsion Engineer (Early) to join our closely integrated team, driving the development of our 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.

Requirements

U.S. Person status is required as this position needs to access export controlled data.
Bachelor's degree in mechanical, electric propulsion, or other aerospace-related engineering discipline.
0-2 years of propulsion design and test experience
Experience with handling and testing pressurized systems
Strong knowledge of propulsion, spacecraft systems, and range safety (SSCMAN 91-710) requirements.
Ability to decompose supplier ICDs and communicate requirements to responsible engineering disciplines
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

Nice To Haves

Master's in mechanical, electric propulsion, or other aerospace-related engineering discipline
Experience operating leak, burst, proof test facilities
Experience leading an electric propulsion hot-fire test campaign including (high-voltage power and fluid delivery systems for ground test, data acquisition systems, thrust stands, and plasma diagnostics, are a plus).
Experience with electric propulsion operations in space

Responsibilities

Design electric propulsion system architecture, develop product specifications, and maintain Technical Performance Metrics (TPMs) including power and mass budgets.
Define placement and integration of an electric propulsion system architecture
Documenting and maintaining detailed work instructions, process flow diagrams, assembly, integration, and test (AI&T) procedures for manufacturing operations.
Establish engine degradation model, perform filtration analysis, and demonstrate compliance to dedicated propulsion budgets (leak, power, thermal, etc.)
Design high pressure fluidic systems, fluid system instrumentation, and control components (i.e. tanks, regulators, pressure transducers, thermocouples, solenoid valves, etc.)
Develop qualification and acceptance test plans and support said tests per approved procedures. Testing includes environmental testing such as vibration, shock, and TVAC.
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.
Decompose SSCMAN 91-710 document into Requirements Verification Matrix (RVM), tailor requirements as necessary, and conduct Process Hazard Analyses (PHAs) for internal personnel and facility safety.
Conduct trade studies for electric propulsion components and suppliers, work with supply chain on quotation process, and manage vendors in the supply chain.
Contribute to proposals and business development efforts as needed.
