As a Site Reliability Engineer, you will help us solve some of the unique challenges of blockchain oracle architecture and be primarily responsible for the Chainlink ecosystem's off-chain part.   We are distributed across time zones and continents, and we embrace remote work. In the Infrastructure team, we follow the infrastructure-as-code approach and practice GitOps.

If you think you would do a great job at Chainlink, we are looking forward to speaking with you, even if you don't match 100% of the job requirements: those describe people we've usually had a great time working with, but they're not a tick-box exercise.

Your Impact

    • Support monitoring services that watch over the entire Chainlink network.
    • Deploy and maintain various externally-facing services like reference Chainlink nodes used by developers and customers (including critical services such as Chainlink VRF).
    • Improve the reliability and observability of our internal infrastructure.
    • Provide our engineers with a reliable release pipeline and empower them to release and deploy Chainlink and adjacent tools extremely quickly.

Requirements

    • 5+ years of relevant professional experience. You have a software engineering background or an operations background and have worked as an SRE (or in a very close position) before.
    • Experience with system architecture. You can create a design document for a cross-region load-balancing app with five microservices, a PostgreSQL cluster, a caching layer, and a Kafka queue—and then implement it on AWS.
    • Experience with CI/CD pipelines. You can troubleshoot an existing pipeline or build your own, and you've probably worked on both software delivery and cloud-based services deployment.
    • Experience with distributed systems and container orchestration. You have built or maintained complex Kubernetes clusters before.
    • Ability to read and write code. You can understand precisely why a recent code change led to degraded performance; you can write scripts and tools to automate routine tasks and eliminate toil.
    • Strong communication skills. You can give and receive constructive feedback, and you do not shy away from planning meetings and code reviews.

Preferred Qualifications

    •  Professional experience with Golang, TypeScript, or both.
    • Excitement for blockchain, Web 3.0, and similar decentralized technologies.
    • Experience running blockchain full node operator is a big plus.
    • Experience with Chainlink as a developer or a node operator is a big plus.
    • Comfort working with network protocols, proxies, and load balancers.
    • Experience with information security and DevSecOps.
    • Experience working remotely in a distributed team.
    • We are giving slight preference to candidates who live in the UTC to UTC+8 range due to our on-call schedule for this particular opening.
