About The Position

Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Engineers and technicians work side by side, with deep collaboration and real-time feedback, to shape how we build better and faster. With a manifest and a launch date, it’s up to the team to deliver on Terran R: solving challenges in real time, optimizing for scale, and constantly improving processes. As the vehicle evolves, so will the factory, with opportunities to apply automation, machine learning, and advanced technologies. What we build here sets the blueprint for the future of scaled launch. This role is responsible for owning hardware from design release through build, test, and delivery for engine or vehicle systems, taking full responsibility for execution readiness and product quality across subassemblies and integrated systems. The role involves developing and releasing detailed build flows, work instructions, and test procedures to enable repeatable, high-quality execution across first builds and maturing programs. It also includes supporting first article builds in a fast-paced environment, focusing on manufacturability, repeatability, and quality, while developing scalable processes that enable a smooth ramp to higher production rates. The engineer will provide hands-on floor support during build and test, resolving issues in real time, incorporating technician feedback, and driving continuous improvement across hardware flow and process discipline. Coordination across design, supply chain, production, and test teams is essential to ensure part readiness, tooling availability, schedule alignment, and smooth handoffs between build stages. The role also contributes to the development of long-term manufacturing systems and infrastructure, including tooling strategies, ERP/MES workflows, and production documentation standards. The shift for this position is Friday - Monday, 5am - 3:30pm.

Requirements

Degree in engineering or a related technical field
2+ years of hands-on experience building and testing hardware in a manufacturing or integration environment
Skilled at investigating hardware issues, resolving non-conformances, and driving root cause analysis with corrective actions implemented effectively
Familiar with general assembly and test procedures, including tolerance stack-up analysis, structural proof testing, and pressurized leak checks
Comfortable interfacing across design, manufacturing, supply chain, and test teams to ensure hardware quality and schedule alignment
Self-starter who can define and roll out new processes from scratch, working collaboratively with technicians, engineers, and external vendors
Proficient in GD&T, CAD, and basic design or test analysis
Experience in at least two of the following: LOX cleanliness, leak checking, sensor checkouts, tube bending, tool design, crane operations, or subassembly builds

Nice To Haves

Experience supporting new aerospace product introduction or transitioning hardware from prototype to production, especially in a high-rate or scaling environment
