Job summary

Unchain Data in Buffalo, NY is seeking an experienced backend engineer to build scalable pipelines that pull contract and permission state across chains and keep them fast, correct, and observable.

You will design and run multi-chain indexing for contracts, roles, and permission changes, and ensure data stays fresh and reconciled against on-chain state.

The role emphasizes tests, end-to-end ownership, and reliable on-call readiness; familiarity with subgraphs or streaming data systems is a plus.

Qualifications

• Strong backend engineering with production data pipelines at scale.
• Hands-on experience indexing EVM chains and decoding contract state.
• A bias for correctness: tests, reconciliation, and clear failure modes.
• Comfort owning a system end to end, from schema to on-call.

Responsibilities

• Design and run multi-chain indexing for contracts, roles, and permission changes.
• Keep evaluation data fresh, correct, and reconciled against on-chain state.
• Build the alerts that fire the moment control shifts on a tracked protocol.
• Make the data layer observable so problems surface before scores do.
