Partner with design engineering to apply Design for Manufacturability (DFM) and design-for-cleanliness principles—sealing machined areas, eliminating hidden cavities where debris can lodge, and enabling clean assembly line layouts—while influencing flight design and vehicle architecture. Design and implement precision tooling and poka-yoke systems for work access, build fixturing, lifting & rigging, fluids, and mechanical/avionics/propulsion testing to eliminate assembly error, prevent FOD introduction, improve quality, and minimize cycle time.

From thousands of gallons per minute of cryogens to tens of pounds per second of high-pressure gas, we develop clever solutions to meet the needs of a demanding test program both today and in the future.

Test Stand Design & Build Engineer (Structures/Fluid Systems)

You will work on large-scale steel structures, factory support systems, ground support equipment (GSE), and tooling structures that must withstand heavy loads, dynamic manufacturing environments, and rapid operational cycles. Perform structural analysis and design of steel, concrete, composite, and similar materials under static, dynamic, vibration, and handling loads using hand calculations and finite element analysis.

Mechanical Engineer, Fluid Systems (Design & Build)

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen. You are the bridge between the product and Capability Engineering: you interpret the product requirements, drive DFM, reverse engineer the product where the data is incomplete, establish the build flow and sequence, and hand Capability Engineering and the foundry a well-defined casting problem to solve.

Hadrian Automation

Build Engineer, Castings

As a member of the Starship Tooling team at Cape Canaveral, you will work with a group of engineers across multiple disciplines to design, build, and activate the launch pad hardware, recovery systems, and production tooling that launch and catch the most powerful rocket in the world. Demonstrate complete end-to-end project ownership: define requirements, develop the concept, size it with hand calculations and analysis, release detailed models and prints, plan fabrication, lead the build, execute activation testing, and hand over to launch operations.

Mechanical Engineer, Starship Tooling

Use expertise in conventional machining (turning, milling, drilling, grinding, broaching, shaping, sawing) and fabrication (sheet metal forming, bending and rolling, hydroforming, spinning, stamping, laser and waterjet cutting, welding, brazing, joining and structural assembly) to improve producibility at the conceptual design stage. It shapes producible designs early in the design cycle, develops manufacturing readiness and technology maturity, and moves hardware into robust production processes at internal GE shops and external suppliers that meet safety, quality, delivery and cost goals.
