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…

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.

About the Team

The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms‑up decision‑making, free from technical gatekeeping, where ownership and accountability are key at all levels.

About the Role

The COPV team is responsible for delivering the critical high‑pressure gas storage vessels for Terran R. These pressure vessels store a variety of gases across a wide range of pressures and temperatures, making them some of the most demanding hardware on the vehicle. The team works closely with partners across the company and throughout the supply chain to ensure performance can be achieved safely, reliably, and at scale.

Projects and Responsibilities

• Partnering with third‑party vendors in the design and analysis of gas storage COPVs.
• Working with other thermo‑fluid engineers on vehicle gas system design and operation.
• Establishing test campaigns for the qualification and acceptance of COPVs; performing tests and reviewing data.
• Supporting integration of COPVs on the rocket.
• Supporting flight operations and reviewing flight data.
• Selecting, developing, and qualifying materials and process controls.
• Selecting, vetting, and managing vendors.
• Performing trade studies to improve gas storage solutions for near‑future vehicles.
• Assessing long‑term COPV design and manufacturing plans.

About You

• Undergraduate degree in engineering or a technical discipline.
• 2+ years of relevant technical experience.
• Understanding of pressure vessel engineering fundamentals.
• Experience applying knowledge of fluid and mechanical system design and operation.

Nice to Haves, but Not Required

• Experience working with COPVs or other composite structures.
• Experience in a creative and fast‑paced development environment, working with autonomy.
• Experience with CAD and FEA.
• Experience with launch vehicle systems.

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Compensation will be determined based on experience, qualifications, and other job‑related factors. The total rewards package includes competitive salary and equity, generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more.
