Build Reliability Engineer II Long , California

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. Achieving commercial success with Terran‑R unlocks new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of a culture where autonomy, ownership, and impact exist at every level. You’ll solve problems that haven’t been solved before, help develop a rocket, a factory, and a business from the ground up, and collaborate across teams, shape decisions, and see your work come to life in record time.

The Reliability team ensures quality is built into every stage of the Terran‑R design and production process, embedding reliability from the very beginning. The team works directly with design, manufacturing, test, and launch teams to stay close to the hardware, understand constraints, and proactively shape decisions. As the program moves from development into production and scaled operations, we establish the right processes, controls, and inspections without slowing progress.

Success means creating a quality system that scales with the Terran‑R program and Relativity as a whole.

• Ownership of design: drawing standardization, design for manufacturability (DFM), and configuration management.
• Planning: review work instructions, develop processes, standardize rework/repair documentation.
• Manufacturing: oversee in‑process build verification, coordinate work flows.
• Drive initiatives to facilitate quality in the launch vehicle program, including spearheading specification development, creating walk‑down checklists, supporting automation for quality inspection, and assisting in DFM practices.
• Develop strong relationships with Engineering, Additive, Manufacturing, Test, and Launch teams to ensure all objectives are met.

• Bachelor’s degree in Engineering or STEM field, and a minimum of 3 years experience as a Quality Engineer in a fast‑paced manufacturing company.
• Extensive experience interfacing with design engineering, manufacturing, production and test personnel.
• In‑depth knowledge of aerospace manufacturing/complex assembly practices and typical quality processes and controls.
• Working knowledge of PLM, MES, ERP and QMS software and proficiency with geometric dimensioning and tolerancing (GD&T).
• Ability to solve difficult problems creatively and coordinate across multiple teams, establishing clear goals for projects.
• Excellent communication skills, with experience presenting to team members, leaders, and senior management, and strong process development knowledge.

• Experience with FMEA, APQP, SPC, and PPV.
• History of New Product Introduction (NPI) of hardware systems into manufacturing, test, and production environments with proven success.
• Familiarity with high‑volume inspection methods and data‑driven acceptance methods.
• Understanding of AS9100/ISO
  9001 application in an aerospace program.
• Self‑starter demonstration of defining, owning, and rolling out a process from scratch.
