SUMMARY

We are seeking an experienced Propulsion Test Engineer to join our test operations team at our manufacturing and test facility in Briggs, TX. This role is for a hands-on test professional with proven expertise in liquid propulsion testing who can lead complex test campaigns and drive operational excellence in our hypergolic test programs.

As a Test Engineer, you will take ownership of test operations for the Spectre propulsion engine and other liquid propulsion systems supporting the Blue Ghost lunar lander program. You will leverage your experience with liquid rocket propulsion to plan and execute critical hotfire testing, lead anomaly resolution efforts, and mentor junior test personnel. Your expertise will directly impact mission success as we prepare our systems for lunar missions.

Testing Spectre will have a direct impact on the success of future lunar missions and will ultimately drive changes to the landscape of our space industry. Specter is an engine built on site, tested on site, and operated by you to be ready to fly to the lunar surface and beyond.
