Principal Turbomachinery Engineer, Turbine Development

<div class="content-intro"><p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our&nbsp;Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch&nbsp;capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new&nbsp;opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond&nbsp;the known.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and </span><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now&nbsp;is a unique moment in time where it’s early enough to leave your mark on the product, the process, and&nbsp;the culture, but far enough along that Terran R is tangible and picking up momentum. The most&nbsp;meaningful work of your career is waiting. Join us.</span></p></div><p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong>About the Team:</strong></span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">The propulsion team at Relativity is responsible for the successful development of the engines that will power the Terran R vehicle. We own their design from concept through to launch and reuse. Our team partners heavily with manufacturing, test, launch, and integration teams, striving to develop our engines in record time and to support Terran R's first launch in 2026. As part of this team, you will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, seeing them mature and eventually bring Terran R into space.</span></p> <div class="p-rich_text_section"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong data-stringify-type="bold">About the Role</strong></span></div> <div class="p-rich_text_section"><br><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">We are looking for a technical expert who can help advance the state of the art of turbine design for space applications. You will collaborate closely with the propulsion development and manufacturing teams to incorporate improvements into future designs. In order to be successful in this role, you should be someone who thrives in ambiguity and is able to drive their own projects to completion. You must have the passion, tenacity and resolve to work through challenging issues unique to rocket turbopumps. We are looking for someone multifaceted, and capable of working at the interfaces of design, development, and analysis of turbomachinery. Ideally, you are someone who has come from a fast paced, aerospace environment, having completed difficult projects while collaborating effectively with multidisciplinary groups.</span></div> <div class="p-rich_text_section"><br> <div class="p-rich_text_section"> <div class="p-rich_text_section"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong data-stringify-type="bold">About You</strong></span></div> <ul class="p-rich_text_list p-rich_text_list__bullet p-rich_text_list--nested" data-stringify-type="unordered-list" data-list-tree="true" data-indent="0" data-border="0"> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Degree in engineering or related technical field and 15+ years of relevant experience</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with turbine design, performing aerodynamic and structural analysis.</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with LCF and HCF methodologies</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with transient thermal/aerodynamic analysis</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with forced response analysis</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Knowledge of industry standard turbomachinery design and analysis</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Strong communication skills</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Knowledge of turbopump assembly procedures, including rotor balancing, interference fits, clearance checks, structural proofing, and leak checks</span></li> </ul> <div class="p-rich_text_section"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong data-stringify-type="bold">Nice to haves but not required:</strong></span></div> <ul class="p-rich_text_list p-rich_text_list__bullet p-rich_text_list--nested" data-stringify-type="unordered-list" data-list-tree="true" data-indent="0" data-border="0"> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with in-situ mode shape/ blade deformation measurement</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience overseeing turbomachinery development and/or test campaigns</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Proficiency in Siemens NX and Teamcenter</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience in a startup or agile development environment</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;" data-stringify-indent="0" data-stringify-border="0"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience working in a flight development program</span></li> </ul> </div> </div><div class="content-pay-transparency"><div class="pay-input"><div class="description"><p><span style="font-size: 14px;">At Relativity Space, we are committed to transparency and fairness in our compensation practices.
