Propulsion Test Engineer I

Relativity Space • Stennis Space Center, MS

6h • Onsite

About The Position

As an entry level Propulsion Test Engineer at Relativity Space, you will be responsible for designing and operating rocket engine test stands for our Terran R engines and stages. Entry level engineers at our Stennis facility work in partnership with experienced operations and ground systems engineers and technicians to build and modify test facilities, as well as participate in test campaigns to flight qualify our hardware. You will be directly engaged in daily test operations, maintenance, construction, and commissioning activities in the field. The entry level role may include aspects of both designing ground systems and conducting test operations. This role requires a valid driver's license in order to operate vehicles while on the test site and may involve up to 25% travel to production and launch locations.

Requirements

• 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
• 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

Nice To Haves

• Drive to deliver on tight schedules, especially when unconventional & creative solutions are necessary
• Proficiency in 3D modeling and drafting, including GD&T

• 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%

Benefits

• Competitive salary and equity
• Generous PTO and sick leave policy
• Parental leave
• An annual learning and development stipend
