Location: Los Angeles, CA (On-Site) Team: Supply Chain Reports to: CEO
The US needs 1.5 terawatts of new power by 2035. AI has scaled beyond our ability to build power, and the existing power supply chain is the bottleneck. You cannot buy a new gas turbine until 2030: order books at GE, Siemens, and Mitsubishi stretch past 2030. Turbine prices have nearly tripled since 2019. The future demands a new kind of hardware company, building a new kind of turbine. That’s Stone.
We are America’s Turbine Company, designing, fabricating, and deploying turbines for a $200B+ market that’s tripling by the early 2030s. We are building our own factories. We are delivering our own natural gas, steam, and advanced turbines. And we are doing it with an AI stack built specifically for hardware.
Natural gas turbines are the first leaf on a multi-decade tech tree. The same physics kernel, the same factory, and the same team will deliver nuclear turbines, geothermal turbines, heat recovery systems, and propulsion engines. Nat gas is how we get going. Nuclear (on and off planet) is how we become a generational company.
This is a founding team role: one of the first engineers who will define the culture, pace, and competency bar at Stone. Every founding employee has shipped hardware at scale, and we keep doing it for the love of the game. The data is only half the moat; the ability to turn our designs into atoms rapidly closes the loop. In power generation, we are both Nvidia and TSMC.
You’re the first supply chain hire. You will inform the rest of the strategy and delivery of the organization. The best candidates will hire the rest of the team.
This role as a sourcing engineer focuses on building and owning the external supply base for highly manufacturable turbines for power generation. The position involves identifying suppliers, qualifying processes, negotiating terms, and driving parts from RFQ to dock. Stone is usually anti-verticalization. We know there are hundreds of manufacturing experts on the other side of a PO. Your job is to find them, and bring their knowledge to our design.
Key responsibilities include owning commodities end-to-end (machined components, castings, forgings, sheet metal, etc.), running competitive sourcing events, qualifying new suppliers, negotiating contracts, placing and expediting POs, and resolving the initial supplier quality and delivery issues on the shop floor. The sourcing engineer will be the primary owner of their commodity, tasked with developing the supply strategy from prototype through serial production.
