Senior COPV Engineer

About The Team

The Stage Fluids team designs and delivers the propellant, pressurant, pneumatics, and other fluid systems that turn structures into functioning rockets. The team has full ownership across design, production, test, and flight, maintaining a holistic view of Terran R, focused not on isolated parts but integrated functionality. Working on-site at the factory means you're never far from the hardware, enabling rapid iteration and tight feedback loops across design and manufacturing. You won't just be handed requirements: you'll be expected to ask the right questions, collaborate with partners across the company, and ultimately find the best solutions for Terran R.

About The Role

You will be a part of developing the architecture for the upcoming Terran R vehicle and will be responsible for charting the company's path for gas storage on a reusable rocket—both near-term and long-term. Here are some examples of projects you could be working on:

• 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 COPVs on the rocket
• Selecting, vetting, and managing vendors
• Performing trade studies to improve gas storage solutions for the near future vehicles
• Assessing long-term COPV design and manufacturing plans

About You

• Undergraduate degree in engineering or a technical discipline
• 5+ years of relevant technical experience
• Experience applying 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
