<div class="content-intro">At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle 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. 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 technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.</div>About the Team:  The Interplanetary Sciences Program was established to expand access to scientific exploration across our solar system. Its mission is to make planetary research faster, more affordable, and more capable than ever before by rethinking how science missions are designed, built, and operated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs. By creating a sustainable model for interplanetary exploration, we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge, broadens participation, and inspires the next generation of explorers. About the Role: We are seeking a driven science payload manager to lead the delivery, integration, and operations support for a science instrument suite. This is a highly technical role for a leader who combines deep technical and scientific competency, is confident in making risk-based decisions, and has a sense of personal ownership over the success of the instrument from build phase through on-orbit operations. In this role you will serve as the responsible engineer for working with our partners to ensure the delivered instruments meet or exceed the desired science capability, and proceed smoothly and efficiently through environmental testing, spacecraft integration, commissioning, and in-space operations. This role requires you to understand the science and the engineering, manage risk proactively, make hard decisions under uncertainty, own the outcomes, communicate clearly to multiple stakeholders, and care deeply about the science results. You will need to understand the engineering systems and be an advocate for how they should be designed to support and enable collecting exceptional science on this and future missions. You will operate as part of a fast-moving, lean, multi-disciplinary team driven by mission success.
