About The Company
Relativity Space is on a mission to make access to space more reliable and routine. Our medium-to-heavy lift reusable rocket, Terran R, will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.
About the Role
<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><span data-contrast="none">About the Team:&nbsp;</span></strong></span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">The Avionics team is responsible for the full lifecycle of Terran R’s nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you’ll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong><span data-contrast="none">About the Role:</span></strong></span></p> <p><span style="font-size: 10pt;">As a Power Electronics engineer within the Avionics team, you will lead high power devices through the product lifecycle to include initial design, board bring-up, design verification, qualification, initial flight production, integration, and vehicle operations. You will work with cross-functional partner teams across the company to help the team make the best possible decisions for the vehicle. A strong candidate for the role will have a deep technical background in power electronics design, specializing in battery systems, power distribution, or related devices such as converters, inverters/rectifiers, or motor controllers. &nbsp;</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong><span data-contrast="none">About You:</span></strong></span></p> <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Bachelors degree in Electrical Engineering, Computer Engineering, or a related field&nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">7+ years of experience in power electronics design for harsh environments and mission-critical applications such as launch vehicles, spacecraft, aircraft, or robotics&nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Experience with eCAD software such as Altium or equivalent &nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Experience with hardware bring-up, validation, debugging, and data analysis&nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Experience with board-level design from concept to manufacturing&nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Experience working with highly cross-functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions&nbsp;</span></li> </ul> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong><span data-contrast="none">Nice to haves but not required:&nbsp;</span></strong><span data-ccp-props="{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}">&nbsp;</span></span></p> <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Familiarity with embedded software development and integration for avionics systems&nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Experience with design for reliability and manufacturability of avionics hardware and systems&nbsp;</span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-size: 10pt;">Technical expertise in several power electronics &nbsp;areas, such as motor drives and control, DC-DC converters, load switches, high voltage DC electronics</span></li> </ul><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.
