At LiquidPiston, you won’t be one engineer among hundreds working on a small piece of an established product. You’ll be part of a lean engineering team working on technology that is still being invented. Your work can move quickly from an idea to a drawing, from a drawing to a prototype, and from a prototype to a running engine. You’ll see the results of your engineering decisions firsthand and have the opportunity to influence the direction of the technology. The problems are difficult. The timelines are ambitious. The answers aren’t always obvious. That’s exactly what makes the work exciting. If you enjoy figuring out why something failed, building a better solution, testing it, and trying again, you’ll fit right in. About LiquidPiston LiquidPiston, Inc. is a technology startup reinventing the internal combustion engine through a patented thermodynamic cycle and novel rotary architecture. Our compact, high-efficiency engines are being developed for demanding applications across defense, aerospace, and commercial markets.
