A thriving economy in space is needed to make life on Earth more vibrant, sustainable, and equitable. Space technology will enable global access to information, solutions to climate change, answers to global food security, products that transform healthcare, clean energy production, and more. Today, rocket launch options are slow, expensive, and unreliable. Stoke is building the world’s most efficient fully and rapidly reusable rocket designed to fly daily that will radically increase access to space and open up the space economy to safeguard our precious home, Earth.


Fully reusable launch vehicles are the key to seamlessly connecting Earth and space. As the Stage 1 Thrust Chamber Assembly (TCA) Responsible Engineer, you will have extreme ownership over all aspects of the Stoke’s first stage regeneratively cooled thrust chamber and nozzle optimized for our full flow staged combustion engine cycle. You will own the CAD design, regen circuit layout, additive manufacturing approach, and testing of a TCA designed for a 100% reusable rocket designed to fly daily. You will work closely with the rest of the first stage engines design, manufacturing, and operations teams through all phases of the product lifecycle. You must be ready to stay focused, move fast, self-direct, and learn on the fly.


  • Own the entire engine thrust chamber assembly (TCA); this includes the regen-cooled copper main combustion chamber and regen-cooled nozzle extension, inlet and outlet manifolds, and turbopump and main injector interfaces.
  • Own the CAD and product definition.
  • Design and iterate the regenerative cooling channel design for optimal cooling within allowable pressure drop.
  • Develop, execute, and improve the manufacturing plan for the TCA; procuring and managing all hardware for the TCA.
  • Define the verification plan and manage the execution of development test campaigns on during engine testing. Review test data and determine compliance with specifications.
  • Track risks and execute appropriate mitigation plans.


  • 3+ years of experience in design, build, and testing of rocket engines and thrust chambers with regenerative cooling channels.
  • Experience with detailed mechanical design including machined parts, additive parts, weldments, fasteners, seals, and especially assemblies.
  • Experience with various welding approaches (GTAW, Laser, and EB Welds).
  • Strong fundamentals in GD&T, tolerance stackups, and material selection.
  • Strong fundamentals in heat transfer, fluid mechanics, compressible flow, and cryogenics.
  • Extensive experience with CAD tools and configuration management (Siemens NX and Teamcenter preferred).
  • Extensive experience managing large CAD assemblies and associated drawings.
  • Strong knowledge of systems engineering fundamentals, and ability to apply that knowledge in practical ways to a fast-paced development program.
  • Experience reviewing rocket engine test data.
  • Hands on experience performing fabrication, assembly, and/or testing
  • Ability to lead
  • Ability to follow
  • Excellent written and verbal communication
