Zero-Knowledge (ZK) Jobs in Crypto & Web3
Zero-knowledge engineering roles build the cryptography behind private and scalable blockchains, writing circuits in Circom, Halo2, or Noir and working with SNARK and STARK proving systems. Engineers design constraints, optimize proving and verification costs, and reason carefully about soundness and security.
These roles power ZK-rollups, privacy protocols, identity systems, and verifiable computation, often pairing deep math and cryptography with Rust or C++ for high-performance provers. Familiarity with elliptic curves, polynomial commitments, and recursion is common, and demand for proven circuit experience is high.

Frequently asked questions
What languages and tools do ZK engineers use?
Circuit development uses Circom, Halo2, Noir, or arkworks, while provers and tooling are often written in Rust or C++. Strong math and cryptography knowledge underpins all of it.
What is the difference between SNARKs and STARKs?
SNARKs produce small proofs and often need a trusted setup, while STARKs are transparent and post-quantum friendly but generate larger proofs. ZK roles may use either depending on the system.
Do I need a cryptography PhD for ZK jobs?
Not always. Research roles may favor advanced degrees, but many ZK engineering positions value strong math, hands-on circuit experience, and the ability to ship correct, optimized constraints.
