Job description

Job Overview

Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, unlocking new opportunities for science, exploration, and innovation. Join a team where autonomy, ownership, and impact exist at every level.

Team

The Stage Manufacturing team turns design into reality, owning the build of Terran R’s primary structures. Engineers and technicians work side by side, collaborating in real time to shape how we build better and faster. The team tackles challenges in real time, optimizes for scale, and constantly improves processes.

Role

The Tube Manufacturing team works alongside vehicle design and test teams to develop hardware that enables Terran R reusability. The Manufacturing Engineer will own:

• Advocate for scalable manufacturing in product design trades and reviews.
• Build flow planning, large‑volume part logistics, tooling design, conceptualizing & sourcing.
• Fast‑paced issue dispositions.
• Complex mechanical assembly work planning and execution.
• Conceptualize, develop, and stand up a cutting‑edge bending and welding work cell capable of meeting the demanding requirements of the AeonR and TerranR programs.
• Drive assembly first build and test efforts through design for manufacturability guidance, assembly sequencing, mBOM development, build and test work order creation, and specification authoring.
• Implement innovative tooling solutions for both new and existing products, streamlining production to support increased output while reducing operational complexity.
• Establish and enforce standard practices, troubleshooting guides, and standardized repair procedures, reviewing and approving planning documents.
• Streamline and optimize existing production systems, proactively identifying cost‑saving opportunities while enhancing quality and efficiency.
• Demonstrate ingenuity and autonomy by introducing novel ideas and implementing them with utmost attention to safety, quality, and reliability, ensuring timely completion of projects.

Qualifications

Bachelor of Science degree in aerospace, mechanical, or manufacturing engineering.

• Minimum 2+ years of experience building and testing hardware in a manufacturing environment (internship experience acceptable).
• Experience interfacing with design engineering, manufacturing, and production personnel.
• Extensive experience managing a large scope of ownership.
• Experience authoring work instructions and/or test procedures for mechanical and/or fluid assemblies.
• Self‑starter who defines and owns a process from scratch and rolls it out through clear communication.
• Nice to haves (not required):

• Understanding of orbital tube welding (OTW), tube bending, TIG welding, metallic fabrication, assembly procedures, and tooling design.
• Strong understanding of GD&T and drafting principles.
• Working knowledge of typical manufacturing execution systems and quality management systems.
• Working knowledge of rocket subsystems including structures, mechanisms, high‑pressure gas systems, and/or avionics.

Compensation and Benefits

Salary: $102,000—$156,000 USD.

We are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job‑related factors. Relativity Space offers competitive salary and equity, generous PTO and sick leave, parental leave, an annual learning and development stipend, and more.
