Backend Developer Jobs in Crypto & Web3

Backend engineers in web3 build the services that sit between users and the chain: APIs, indexers, event listeners, notification systems, and the data layers that make raw blockchain activity usable. The work blends conventional backend skills with the quirks of distributed ledgers, like handling reorgs, retries, and unreliable RPC nodes.

Common stacks include Node.js, Go, Rust, or Python alongside PostgreSQL, Redis, and message queues, often paired with The Graph or custom indexers. Employers want engineers who can design scalable, fault-tolerant systems, model on-chain data cleanly, and keep services responsive even when the network is congested or providers fail.
