HN Jobs

O(1) Labs | San Francisco, CA | Product Engineer, Cryptography Engineer, Protocol Engineer | Full Time | Onsite | https://codaprotocol.com At O(1) Labs, we're building the Coda Protocol, the first cryptocurrency to have a constant-sized blockchain. We use recursive zk-SNARKs to compress historic state in Coda's blockchain so that nodes don't have to store all the data going back to the first transaction. Compare this to Bitcoin or Ethereum whose blockchains already have hundreds of GBs of data, and keep growing. We're excited about this tech because it allows all the nodes in a network to be full nodes (no SPV's!) and enables applications that can use the entire blockchain embedded in a phone or a browser. We're well funded and backed by some of the top investors in the crypto / blockchain space. I'm on the product team, and we're looking for product engineers - but you can find all the roles we're hiring for here - https://codaprotocol.com/jobs.html. Our stack is OCaml on the protocol side, and ReasonML + React on the front-end. All of our code is open source - https://github.com/codaprotocol/coda. Feel free to reach out to me if you have any questions or want to meet in person for a coffee, if you're based in the bay area. My email is pranay@o1labs.org.
