Build and own data products and resilient distributed systems for Chainlink's Data Feeds. Responsibilities include implementing trust-minimized off-chain computation, aggregating external data, smart contract development (Solidity, Move, Rust), partnering with research, modeling failure scenarios, and managing architecture. Requires at least 4+ years of professional software engineering experience, experience in blockchain/Web3 and smart contracts, CS fundamentals, systems design, and a B.S. or higher in a technical field. Tech stack: Golang, Solidity, TypeScript, Rust, Postgres, Terraform, AWS. Role is global and remote; candidates should try to overlap some working hours with Eastern Standard Time (EST).

Chainlink Labs is hiring a Software Engineer I for the CCIP Protocol team to build and maintain backend services that enable secure, reliable cross-chain message execution. The role emphasizes distributed systems design, protocol security, operational resilience, and performance optimizations (RPC and latency). Candidates should have backend engineering experience (Go, Rust, or TypeScript) and familiarity with blockchain/DeFi concepts; the company is remote-first and requests some overlap with Eastern Standard Time.

Work on the CRE platform to deliver core capabilities across CLI, Go and TypeScript SDKs, frontend services and backend APIs. Improve scalability, workflow durability, reliability, and developer experience. Requires experience operating production backend systems at scale, advanced Go proficiency, and distributed systems design. Remote-global role with requested overlap with EST hours.

Work on foundational CRE platform capabilities including backend services, APIs, and distributed systems to improve reliability, scalability, and workflow execution durability.
