About the Role
As an entry-level Propulsion Test Engineer, you will work with test stands and test articles (high-energy components, engines, and full stages) for Terran R. You'll have the opportunity to see a heavy-lift orbital launch vehicle and its many parts come to life through testing. Test and flight articles are designed and built in our Long Beach factory, then sent to Stennis to undergo rigorous testing. Entry-level engineers at our Stennis facility work in partnership with experienced engineers, technicians, and welders to build and modify test facilities and participate in test campaigns to evaluate complex rocket hardware. You'll solve a variety of technical problems across broad ranges of timeframe, complexity, and impact, and continuously improve processes to move faster and more efficiently. The role includes three focus areas - Design & Build, Operations, and Integration. You'll initially be placed on a team in one focus area, with opportunities to work across focuses as you develop in the role, particularly between Operations and Integration which work closely together.
[Design & Build Focus]
Design fluid systems (gas, liquid, cryogenic) including Piping & Instruction Diagrams (P&IDs), analysis, and component selection
Design structural and mechanical systems including 3D modeling, analysis, and fabrication drawings
Source components and develop detailed fabrication work instructions
Bring new test stands to life by managing fabrication, activation, and initial operations
Design and implement upgrades to operational test stands to enable new test capabilities
Maintain test stands through preventive maintenance and rapid response to anomalies & equipment failures
[Operations Focus]
Conduct test operations on high-energy components, engines, and stages
Control test stand and test article through GUIs and automation while monitoring cameras and telemetry
Conduct flight acceptance, qualification, and development testing campaigns to validate designs and continuously improve the rocket
Develop and optimize GUIs, procedures, control automation, and data review processes
Prepare test articles for testing through inspections, functional checks, leak checks, and managing non-conformances
Bring new test stands to life and support modifications and maintenance on existing facilities
Operations Engineers typically work a scheduled morning or evening shift
[Integration Focus]
Manage test articles through test prep, post-test processing, and repairs
Author work instructions for test articles and coordinate work with technicians and quality inspectors
Manage non-conformances, author corrective work instructions, and implement part requirements
Maintain work instructions current with evolving build specifications and drive standardization across sites
Incorporate feedback and optimize part usage to streamline hardware flow and reduce waste
Integration Engineers typically work a scheduled morning or evening shift
