It's time to build

We enable the most innovative, most fun, most exciting blockchain applications.

Join us, and help unlock everything that the blockchain has to offer.

You will build fundamental, useful blockchain infrastructure. You'll help radically expand the design space of what’s possible on blockchains, becoming an expert on blockchain scalability in the process.

You will work on a fast-moving project, with a high-quality, fast-moving team, at the earliest stage of development. We're engineers at heart, and prioritize a culture of shipping well-designed systems, iterating quickly, and embracing failure.

You will help set the direction of our product, our team, and our company culture. As a founding member of our team, the company will grow with you, and you will grow with the company.

You will receive a highly competitive salary, significant equity in the company, and full benefits.
