Remote - Full-time
All roles with Chainlink Labs are globally remote based. We encourage you to apply regardless of your location.

The infrastructure team enables Chainlink development and maintains services that support the health of the most widely-adopted oracle network in the world. As a DevOps Engineer, you will help us maintain the Chainlink infrastructure, ensure reliable work of internal and customer-facing services, and empower the entire engineering organization to do their best work.

This job would be perfect for someone who has a strong operations background and would eventually like to grow into an SRE role. The infrastructure team is expanding, and you would have plenty of opportunities to build up your skillset in different areas.

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. Our on-call rotation uses the follow-the-sun pattern: you will be on call some of the time, but there should not be any overnight shifts.

We all have different backgrounds and are determined to help you succeed no matter where you are or who you are. 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

    • Maintain full nodes for various blockchains Chainlink supports and find ways to deploy and manage them more efficiently.
    • Deploy new Chainlink nodes and ensure their reliability.
    • Understand blockchain-specific monitoring in great depth and help the team cut down on noise by fine-tuning alerts.
    • Pair with engineers from across the company to help with troubleshooting, deploy new services, and figure out how to increase developer velocity and eliminate pain points.

Requirements

    • 3+ years of relevant professional experience. You probably have an operations background, have worked in a DevOps team before, and are familiar with most tools from our stack (below).
    • Experience with CI/CD. You know how to deploy your services reliably and have used tools like GitHub Actions, CircleCI, TravisCI, or Jenkins to achieve that.
    • Experience with scripting and configuration management. You can write scripts to automate routine tasks and have familiarity with tools like Ansible and Packer.
    • Experience with monitoring and logging. You know how to export metrics to Prometheus, have built a Grafana dashboard or two, and have experience with a centralized logging solution like the Elastic Stack, Splunk or LogDNA.
    • Experience with distributed systems and container orchestration. You have maintained or even built Kubernetes clusters before and feel comfortable deploying completely new services on them.
    • Strong communication skills. You can give and receive constructive feedback, and you do not shy away from planning meetings and code reviews.

Desired Qualifications

    • Excitement for blockchain, Web 3.0, and similar decentralized technologies.
    • Experience running blockchain full nodes would give you a considerable advantage in this role.
    • Experience with Chainlink as a developer or a node operator is a similarly big plus.
    • Experience with GitHub Actions and self-hosted runners in particular.
    • Experience working remotely in a distributed team.
    • A strong desire to grow and challenge yourself. While this role is mainly focused on maintenance, we would expect you to constantly find ways to improve and automate services under your purview.
    • 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.
Our Stack
Some of the tools and services we use daily or almost daily are:

AWS; Terraform/Terragrunt; Kubernetes, Calico and ArgoCD; Prometheus and Grafana; GitHub Actions; Packer

We expect you to be comfortable with most of those tools and proficient in at least a couple of them.
