Job description

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. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you’re not just executing tasks; you’re solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team

The Reliability team at Relativity Space 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, this is the time to establish the right processes, controls, and inspections without slowing progress. The team plays a key role in balancing risk, fostering a culture of ownership, and making sure speed never comes at the cost of reliability.

About the Role

• Lead the execution of supplier development strategy, ensuring supplier performance aligns with Terran R production, launch, and compliance requirements (AS9100/ISO 9001).
• Serve as the primary technical point of contact for assigned suppliers, resolving manufacturing and quality issues to protect production schedules and build cadence.
• Drive supplier performance management by establishing and tracking key metrics and scorecards, including PPM, yield, and PPAP timing, to improve overall supplier capability.
• Lead NPI efforts by selecting manufacturing methods, evaluating suppliers, and developing scalable production processes in partnership with Engineering and Supply Chain, including DFM reviews, PPAP/FAIR approvals, and APQP execution.
• Manage supplier corrective actions, root cause investigations (e.g., 8D), and compliance verification against AS9100, ISO 9001, and NASA quality standards to drive sustained improvements across the supply base.
• Own supplier risk escalation and resolution, applying disciplined problem‑solving to ensure rapid recovery on quality or capacity issues.
• Provide technical direction and day‑to‑day guidance to other engineers, aligning priorities and deliverables.

About You

• Bachelor’s degree in Engineering (Mechanical, Aerospace, Industrial, or a related technical field).
• 8+ years of experience in Supplier Development, Supplier Quality, or Manufacturing Engineering, ideally within aerospace or a high-reliability/safety‑critical industry.
• Proven ability to lead cross‑functional programs end‑to‑end, coordinating across Engineering, Manufacturing, and Supply Chain without direct authority over all contributors.
• Strong technical knowledge of manufacturing processes for space‑ or safety‑critical hardware, including forming, machining, and assembly of metals such as stainless and carbon steels.
• Expert working knowledge of quality systems (AS9100/ISO 9001) and core quality tools (APQP, PPAP, FAIRs, PFMEA, Control Plans), with hands‑on experience driving implementation and compliance.
• Demonstrated ability to define processes from the ground up and deploy them across diverse teams.
• Willingness to travel up to 50% of the work week when needed.

Nice to Have

• Master’s degree in Engineering (Mechanical, Aerospace, Industrial, or a related technical field).
• Professional certification such as Six Sigma Black Belt, ASQ Certified Quality Engineer (CQE), or PMP.
• Familiarity with high‑volume inspection methods and data‑driven acceptance criteria.
• Experience with enterprise applications (PLM, ERP, MES) and proficiency in data analysis.
• Comfortable operating in high ambiguity, setting direction where precedent or data is incomplete.

Compensation

Hiring Range: $128,000 - $176,000 USD. Compensation may include salary, equity, PTO, parental leave, an annual learning and development stipend, and other benefits.
