About the Role

<div class="content-intro">Advanced Reentry Technologies Who We Are: Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions. The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach. Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.</div>Position Overview: As a Senior Propulsion Development Engineer at Inversion, you will design, build, and test liquid and gas propulsion systems for our next-generation Arc hypersonic reentry vehicle, with an emphasis on Attitude Control System (ACS) thrusters, fluid feed systems, and propulsion components. You will own the mechanical design and analysis of fluid networks, manage hardware fabrication, author test plans, procedures, and reports, and lead hot-fire test campaigns. You will work cross-functionally with structures, avionics, software, and test teams to physically integrate propulsion hardware into the vehicle and verify system performance against mission requirements.  Key Responsibilities:  <ul> <li class="x1yc453h xma8rkl xgoqxah xutxfr x1fie51u xgyxj25 x1xobyvs x1elgs31 x1fv8qjw xcy5tzr x1ht4adc xnvauns x1c2l018 x14l7nz5 xuw7688 x1pjt2rx x160d6zm xrxpjvj">Design and analyze propulsion systems, including ACS thrusters, fluid feed systems, and high-pressure fluid networks.</li> <li class="x1yc453h xma8rkl xgoqxah xutxfr x1fie51u xgyxj25 x1xobyvs x1elgs31 x1fv8qjw xcy5tzr x1ht4adc xnvauns x1c2l018 x14l7nz5 xuw7688 x1pjt2rx x160d6zm xrxpjvj">Create mechanical designs, CAD layouts, and fluid line routing for propulsion hardware.</li> <li class="x1yc453h xma8rkl xgoqxah xutxfr x1fie51u xgyxj25 x1xobyvs x1elgs31 x1fv8qjw xcy5tzr x1ht4adc xnvauns x1c2l018 x14l7nz5 xuw7688 x1pjt2rx x160d6zm xrxpjvj">Lead hardware fabrication, integration, and troubleshooting of propulsion components and systems.</li> <li class="x1yc453h xma8rkl xgoqxah xutxfr x1fie51u xgyxj25 x1xobyvs x1elgs31 x1fv8qjw xcy5tzr x1ht4adc xnvauns x1c2l018 x14l7nz5 xuw7688 x1pjt2rx x160d6zm xrxpjvj">Author test plans, procedures, and reports, and lead hot-fire and propulsion test campaigns.</li> <li class="x1yc453h xma8rkl xgoqxah xutxfr x1fie51u xgyxj25 x1xobyvs x1elgs31 x1fv8qjw xcy5tzr x1ht4adc xnvauns x1c2l018 x14l7nz5 xuw7688 x1pjt2rx x160d6zm xrxpjvj">Collaborate cross-functionally with structures, avionics, software, and test teams to integrate hardware and verify system performance.</li> </ul> Required Qualifications: <ul> <li>Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or equivalent technical experience. </li> <li>Typically 5+ years of hands-on experience in the design, build, and testing of high-pressure fluid or rocket/spacecraft propulsion systems. </li> <li>Expertise using CAD software (Siemens NX or equivalent) for mechanical packaging and fluid line routing. </li> <li>Strong foundation in fluid mechanics, thermodynamics, structural mechanics, and materials compatibility. </li> <li>Experience working hands-on with high-pressure fluid components, plumbing (tubing, fittings, manifold blocks), and pneumatic systems. </li> <li>Demonstrated excellent verbal and written communication skills with the ability to write detailed test and hazard procedures. </li> <li style="font-weight: bold;">Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.</li> </ul> Desired Qualifications: <ul> <li>Direct experience with spacecraft Attitude Control Systems (ACS), cold-gas, warm-gas, or monopropellant/bipropellant thruster systems. </li> <li>Familiarity with high-pressure gas system operations, nitrogen/helium systems, and safety-critical hazard controls. </li> <li>Experience with ANSYS Mechanical or equivalent FEA software. </li> <li>Experience using Python, MATLAB, or GFSSP for fluid system analysis. </li> <li>Prior experience performing acceptance and qualification testing of propulsion components or systems in accordance with standards such as SMC-S-016, GSFC-STD-7000A. </li> <li>Prior experience in a fast-paced aerospace startup, collegiate rocket/propulsion team, or small independent hardware team. </li> </ul> Our office headquarters is located in Playa Vista, CA.
