Smart Contract Developer Jobs in Crypto & Web3

Smart contract developers write the on-chain logic that holds and moves user funds, so the role demands a security-first mindset above all else. Whether building in Solidity for EVM chains or Rust for Solana, the job is to design contracts that behave correctly under adversarial conditions and remain upgradeable and gas-efficient.

Day to day, the work spans architecture, thorough testing with tools like Foundry or Anchor, integrating oracles and existing protocols, and preparing code for external audits. Employers prize engineers who reason about invariants, study past exploits, write clear documentation, and treat every line as a potential attack surface.
