About ChainlinkChainlink is the industry‑standard oracle platform bringing the capital markets onchain and powering the majority of decentralized finance (DeFi). The Chainlink stack provides the essential data, interoperability, compliance, and privacy standards needed to power advanced blockchain use cases for institutional tokenized assets, lending, payments, stablecoins, and more. Since inventing decentralized oracle networks, Chainlink has enabled tens of trillions in transaction value and now secures the vast majority of DeFi. Many of the world’s largest financial services institutions have also adopted Chainlink’s standards and infrastructure, including Swift, Euroclear, Mastercard, Fidelity International, UBS, S&P Dow Jones Indices, FTSE Russell, WisdomTree, ANZ, and top protocols such as Aave, Lido, GMX and many others. Chainlink leverages a novel fee model where offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve.About The RoleThis role exists to design and operate the core services that enable secure, fault‑tolerant cross‑chain transactions within the CCIP protocol. It is responsible for strengthening the reliability, performance, and security of interoperability infrastructure under adversarial conditions. The role directly impacts protocol trust, integration velocity, and long‑term ecosystem growth.Your ImpactDeliver backend services that coordinate fast, fault‑tolerant cross‑chain transactions across multiple blockchain ecosystemsImprove system reliability and resilience under adversarial conditions to strengthen protocol trust and uptimeReduce transaction processing latency through optimizations in RPC usage and system performanceEnable seamless integration across EVM and non‑EVM ecosystems, accelerating adoption of CCIPIncrease throughput to scale CCIP to support thousands of concurrent cross‑chain transfers without degradation or backlogBuild internal systems that allow rapid debugging, replay, and resolution of failed transactionsRequirementsDemonstrated strong backend engineering experience using Go, Rust, or TypeScript in production systemsProven track record contributing to or building within crypto‑native projectsDesigned systems with security and reliability as foundational principles, particularly in adversarial or distributed environmentsBuilt or operated backend systems that prioritize fault tolerance, consistency, and high availabilityPreferred RequirementsDemonstrated knowledge of DeFi protocols and ecosystem dynamicsExperience working with cloud infrastructure and containerized systems in production environmentsHands‑on experience interacting with blockchain bridges or interoperability protocolsUnderstanding of security risks specific to cross‑chain or bridge‑based architecturesFamiliarity working with non‑EVM ecosystems such as Solana, Aptos, or similarExperience debugging and operating distributed systems at scaleCommitment to Equal OpportunityChainlink Labs is an equal opportunity employer.
