Propulsion Test Engineer I

Summary

Relativity Space is building rockets to meet the growing demand for launch capacity. As an entry level Propulsion Test Engineer, you will design and operate rocket engine test stands, engage in test operations, and collaborate with experienced engineers to flight qualify hardware.

Responsibilities

• Design advanced propulsion test stands including 3D modeling, fluids, structural, and thermal analysis, fabrication drawings, fluids P&IDs, component lists, and detailed work instructions
• Supervise the construction, commissioning, and initial operations of these facilities
• Solve a variety of technical problems, across broad ranges of timeframe, complexity, cost, and long-term impact
• Support operations on and perform related improvements to existing test stands
• Create, modify, and optimize test sequences, procedures, and data review processes
• Conduct complex propulsion test operations to assess performance of rocket engines and stages
• Directly control and receive telemetry from the test stand and test articles through GUIs and an integrated software suite for control, automation, and data visualization
• Help develop new rocket engine propulsion designs based on real test data
• Potentially travel to production and launch locations, up to 25%

Skills

• Bachelor's degree in mechanical engineering, aerospace engineering, or a related field
• Hands-on fabrication experience using common power tools for projects at work/home/school
• This role requires a valid driver's license in order to operate vehicles while on the test site
• Successful candidates must clear a background check administered by the US government to obtain clearance for on-site work at our government partner location in Stennis, Mississippi
• Drive to deliver on tight schedules, especially when unconventional & creative solutions are necessary
• Proficiency in 3D modeling and drafting, including GD&T
• Strong engineering fundamentals in Thermal, Structures, and Fluids
• Hands-on experience with metalworking, welding, hydraulics, manufacturing, etc
• Working knowledge of fluid components such as valves, regulators, and instrumentation
• Ability to understand and develop fluid P&IDs (Plumbing and Instrumentation Diagrams) for large-scale test stands and supporting ground equipment
• Experience safely operating complex fluid systems, including high pressure gas, cryogenic fluids, flammables, and hydraulics
• Ability to work occasional evening shifts
