Senior Electric Propulsion Engineer

Senior Electric Propulsion EngineerApex is seeking a Senior Electric Propulsion Engineer 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.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 architectureDocumenting 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 developmentDirectly 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.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.8+ years of electric propulsion design and test experienceExperience with handling and testing pressurized systemsStrong knowledge of propulsion, spacecraft systems, and range safety (SSCMAN 91-710) requirements.Ability to decompose supplier ICDs and communicate requirements to responsible engineering disciplinesDemonstrated 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 protocolsPreferred Qualifications:Master's or Ph.D in mechanical, electric propulsion, or other aerospace-related engineering disciplineExperience operating leak, burst, proof test facilitiesExperience 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 spaceWhat We Offer For Full-time Employees:Shared upside: Receive equity in Apex, letting you benefit from the work you createBest-in-class healthcare: 100% company-paid medical, dental, and vision for you and your dependents, plus $100k life insurance at no costComprehensive PTO package: To reset and recharge - starting at 15 days vacation, growing to 20+ days annually, plus 10 paid holidaysCompetitive 401(k) plan: With generous matching - 100% match on first 3%, 50% on next 2%8 weeks paid parental leave: Plus childcare reimbursement up to $350/day for work-related travelDaily catered lunch and unlimited snacks: To keep you fueled throughout the dayVibrant community: Monthly office socials, pickleball tournaments, run club, and gatherings for you and your familyYour dream desk setup: And all the tools you need to be your most productive selfWorld-class Playa Vista office: With the benefit of in-person collaboration with amazing coworkers and flexibility to integrate work and lifeReal impact opportunity: Work alongside experts from aerospace, new space, and other cutting-edge industries to make a lasting differenceReady to join a team where your contributions matter and your future is bright?
