Senior Software Engineer, Data Streams

Chainlink 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. Learn more at chain.link.

This team powers real-time, decentralized data delivery for DeFi protocols where uptime, performance, and correctness are mission-critical.

• Break down complex, ambiguous problems into incremental, production-ready deliverables
• Own reliability through observability, alerting, and operational best practices
• Participate in an on-call rotation supporting critical infrastructure
• Lead code reviews and raise the bar for testing, maintainability, and system design
• Collaborate with product, SRE, and protocol teams to align technical execution with business goals

Requirements

• Expert-level Go experience, including concurrency, memory management, and idiomatic design
• Strong distributed systems and architectural design experience
• Ability to clearly communicate complex technical concepts to diverse stakeholders

Preferred Requirements

• Experience planning and delivering large systems in incremental milestones
• Exposure to SRE practices, production operations, and modern infrastructure (e.g., Kubernetes, CI/CD, Terraform)
• Proven mentorship and ownership of code quality across a team
• Contributions to Go or infrastructure-focused open-source projects
• Deep expertise in a major cloud provider (AWS, GCP, or Azure) or networking protocols
• Experience leading incident response, on-call rotations, or blameless post-mortems
