Our Space Systems team has enabled more than 1,700 missions, ranging from interplanetary exploration, in-space manufacturing to national security and defense initiatives. The team has built spacecraft, payloads, and components for missions to the Moon and Mars, working with partners including NASA, the Space Development Agency, and the U.S. Space Force.

Senior Propulsion Test Engineer I/II

As a Senior Propulsion Test Engineer I/II for our propulsion engineering team based out of Long Beach, CA., your purpose will be to plan, prepare for, and execute engine and propulsion component testing. This includes ownership of the test facility, equipment, and test operations. You will play a critical role in successful development, qualification, and production testing, which directly results in the success of our missions and products. As part of the propulsion development team, you will be involved with engine and propulsion system development from cradle-to-grave, providing test-driven insights that improve the reliability, manufacturability, testability, and performance of our products.

• Set and maintain best practices for all aspects of testing, ensuring a high standard of excellence across the team.
• Provide guidance, training, mentorship, and technical leadership to team members on testing methodologies and processes.
• Review and sign off on test plans and test reports, ensuring quality and compliance with requirements.
• Support engineers and leadership with risk-based decision making to guide the team through development challenges.
• Own the full testing lifecycle, including test planning, setup, instrumentation, execution, data analysis, and reporting.
• Apply a systems engineering mindset to testing activities, integrating with broader engineering efforts.
• Communicate regularly and effectively with a wide range of stakeholders, both internal and external to the team.
• Define, document, and uphold standards of excellence through training, coaching, and review of others’ work.
• Contribute to meaningful, career-defining projects alongside exceptional colleagues in a collaborative environment.
