As the Staff Spacecraft Systems Responsible Engineer within the Interplanetary Sciences Program at Relativity Space, you will own the end-to-end definition, integration, and delivery of the spacecraft bus and its interaction with mission payloads.

You will serve as the technical and programmatic focal point ensuring that spacecraft-level requirements, interfaces, and performance budgets (power, mass, thermal, comm, etc.) are properly defined, tracked, and met throughout the mission lifecycle.

You’ll collaborate across internal teams and with external spacecraft bus providers to ensure mission success, from design and procurement through integration, test, launch, and operations.

This position blends systems engineering, vendor management, and hands-on mission execution, offering a high degree of ownership and impact.

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.
