Sr Manufacturing Engineer, Integration & Test, Second Shift

Relativity Space•Long Beach, CA

1d•$130,000 - $178,000•Onsite

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. The Stage Manufacturing team owns the build of Terran R’s primary structures. This role is on the second shift, which starts at 3pm.

Requirements

Degree in engineering or a related technical field.
5+ 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.
Experience directly authoring and executing test procedures, including acting as a test conductor for integrated system verification.
Familiarity with hazardous operations, fluid system safety, or test execution involving pressurized or high-risk environments.
Experience in a fast-paced and lean environment, including direct vendor engagement, tool development, or leading a small team through an ambiguous build or test effort.

Responsibilities

Own 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.
Develop and release detailed build flows, work instructions, and test procedures to enable repeatable, high-quality execution across first builds and maturing programs.
Support 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.
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.
Coordinate across design, supply chain, production, and test teams to ensure part readiness, tooling availability, schedule alignment, and smooth handoffs between build stages.
Contribute to the development of long-term manufacturing systems and infrastructure, including tooling strategies, ERP/MES workflows, and production documentation standards.
