<p>&nbsp;</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Who We're Looking For</strong></p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Quantum Space is redefining mobility and autonomy beyond Earth orbit. Our Ranger spacecraft deliver high delta-V and sustained on-orbit maneuverability, enabling missions across cislunar and geostationary space that were previously out of reach. We are building the vehicles, infrastructure, and operational expertise that connect and protect assets across the Earth–Moon system<strong>.</strong></p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Quantum Space is seeking a GSE Test Engineer II to support the development and validation of electric propulsion (EP) technologies. This role is a strong fit for an engineer coming from a flight hardware integration and test background — someone who has written procedures, run environmental test campaigns, and worked hands-on with complex systems in controlled environments. You'll bring that discipline and rigor to building and operating our in-house EP test capability.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Where You'll Make an Impact</strong></p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">Design and develop GSE and test infrastructure for electric propulsion systems, including thrusters, feed systems, and support equipment</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Set up, configure, and operate vacuum chamber test environments for EP testing</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Write and own test procedures, safety documentation, and operational workflows</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Execute EP test campaigns end-to-end: integration, operation, data collection, and troubleshooting</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Operate and maintain vacuum systems including turbo, cryo, and roughing pumps, valves, and gauges</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Troubleshoot vacuum performance issues including leaks, contamination, and system instability</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Support instrumentation and data acquisition system implementation</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Contribute to test system requirements covering vacuum performance, thermal constraints, and instrumentation</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Work cross-functionally with propulsion, mechanical, electrical, and AI&amp;T teams to support test readiness</li> </ul> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>What It Takes</strong></p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">BS in Mechanical Engineering, Aerospace Engineering, or a related technical field</li> <li cla
