About Us

LinkPool is a leading validator, oracle provider, infrastructure services and ecosystem developer within the Chainlink ecosystem and wider Web3 industry.

Since 2017, LinkPool has been pioneering modern infrastructure tooling to set precedent and help build an industry that shapes how agreements are formed and settled across all industries. With LinkPool being one of the largest Chainlink Node Operators since its launch in 2019, it is in a unique position to work with and operate across most networks, projects and teams to build its knowledge and help drive the ecosystem forward.

LinkPool is a globally distributed team, and all roles are fully remote.

The Role:

As a Site Reliability Engineer at LinkPool, you’ll be joining our small and driven team to have a core role in building, managing and supporting all aspects of our infrastructure. You’ll work closely with every member of our engineering and business teams to manage the deployment and reliability of new deployments for new networks, be “client facing” by liasoning with projects that we’re working with and have strong ownership of the entire stack to drive change that improves how we think about infrastructure.

You’ll work across our full stack of infrastructure, from creating and maintaining Chainlink nodes, blockchain full nodes, validators, monitoring stack and our Kubernetes cluster setup. As well as this, you will support our existing product engineering teams that work on first-of-their-kind liquid staking products (stake.link) and upcoming iterations of those products rolling out new chains and services.

LinkPool’s infrastructure is fully containerised and fully collocated with wholly owned hardware that we solely manage. This is a unique opportunity to use cutting edge tooling on infrastructure wholly owned without the burden of dealing with cloud pricing.
