<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-size: 10pt; font-family: arial, helvetica, sans-serif;"><strong>About the Team:</strong></span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Dark Matter Lab is a research group within Relativity Space focused on advanced aerospace systems, agentic engineering, and technologies outside the conventional roadmap.&nbsp;We build the infrastructure needed to turn new ideas into engineering capabilities people can actually depend on.</span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><strong>About the Role:</strong></span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">We run a stack of interconnected agentic systems — SybilClaw, yapCAD, Mechatron, Multigraph, local LLM inference, an inter-agent message bus, parametric CAD pipelines, a print farm, and the infrastructure connecting it all. We need an engineer who can own and evolve these systems as they move from prototypes into production engineering infrastructure.</span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">This role is for someone who has deployed an agentic harness (OpenClaw, Hermes, SybilClaw, or something comparable) in a real work environment. You understand what it takes to make these systems reliable when engineers depend on them every day.&nbsp;You’ll learn the stack, improve it, and work with forward-deployed engineers to package portions of it for deployment with internal and external customers.</span></p> <ul> <li style="font-size: 10pt;
