Software Engineers - Auditors - Support Engineers - Formal Verification Engineer

Common Prefix is a science-first blockchain consulting company. Our vision is to make blockchains usable for mainstream users and everyday people – paying at the supermarket, remittances, moving money across borders, saving, investing – and solving the real problems of usability, scalability, and interoperability that come with it.

We're a 30-person team, half scientists (cryptographer PhDs, post-docs, and professors) from renowned universities, half engineers with long web2 experience. A lot of our field is broken and we're trying to make a small contribution in fixing it, by introducing provable security and proper engineering practices across the board.

What we're looking for: Software engineers who can solve problems, are smart, get things done, and enjoy working on the bleeding edge, learning about cryptography, and working from first-principles. Auditors who can write and read code, especially low-level cryptographic implementation code (zero knowledge verifiers, signature schemes, etc), consensus (PoW, PoS), or smart contracts (everything DeFi). Support engineers (junior to early-mid) who enjoy being on the front line of production support (monitor live systems, respond to partner/user issues, triage/debug, and escalate). Formal Verification Engineers with hands-on experience in formal methods to work on machine-checked proofs of blockchain protocols and smart contracts.

Tech stack: Doesn't matter, we'll teach you. But we work mostly with Rust.
