London, Greater London, United Kingdom BLOCKCHAIN Full time

Blockchain is a leading software platform for digital assets.

We're looking for a Coin Nodes Engineer with 2 years of experience, but we are open to consider talented SRE Engineers with 4 years of experience that feel passionate about Coin Nodes and are eager to take progressive ownership of that realm, with a focus on operating the existing infrastructure while modernizing it and making the whole ecosystem and processes more efficient.

In this role, you will focus on the lifecycle of blockchain nodes, from deployment and configuration to ongoing monitoring and performance tuning. You'll play a key part in ensuring nodes remain synced, secure, and scalable, while also troubleshooting complex systems and blockchain-related issues as they arise.

Key Responsibilities:

  • Operate the existing node infrastructure
  • Upgrade existing nodes and research/build/deploy new nodes and validators
  • Create solutions for monitoring and alerting to maximize systems uptime
  • Create automation to help with disaster recovery
  • Leverage existing internal SRE best practices to make coin node provisioning and maintenance more efficient and minimize fragmentation with the rest of the ecosystem
  • Develop new tooling in conjunction with the SRE team to be adopted by the rest of the engineering organization where appropriate
  • Play a critical role in evolving our infrastructure as we develop solutions to complex technical problems involving reliability, latency, bandwidth, and most importantly security
  • Focus heavily on writing tooling to replace manual, repetitive work in a scalable way

Requirements:

  • Deep understanding and demonstrable experience running Bitcoin Core/Cash and Ethereum (geth, parity, openethereum) nodes. Experience with other networks is a plus (Cosmos, Polkadot, Solana).
  • Understanding of blockchain consensus mechanics (PoW/PoS, slashing, jailing)
  • Ability to adopt new technologies
  • Experience with monitoring: Grafana, InfluxDB, Prometheus, or similar.
  • Experience with containerization and service orchestration, including best practices and security. Experience with Hashicorp Nomad, Consul, and Vault is a plus.
  • Strong at automation in at least one programming language, preferably Python/Golang.
  • Linux, including an understanding of resource allocation, network, and/or internals.
  • Solid background with configuration management tools.
  • Experience with using GitOps and CI to make changes, GitHub Actions is a plus
  • Experience with infrastructure as code tools. Experience with complex Terraform deployments is a plus.
  • Experience with database management.
  • Experience working in Data Centers is a plus.
  • Experience with Cloud, preferably GCP

What We Offer:

  • Full-time salary based on experience and meaningful equity in an industry-leading company
  • Hybrid model working from home & awesome office location in the heart of London
  • Unlimited vacation policy; work hard and take time when you need it
  • Apple equipment
  • The opportunity to be a key player and build your career at a rapidly expanding, global technology company in an emerging field
  • Flexible work culture
