Coin Nodes Engineer

Blockchain is the world's leading software platform for digital assets. Offering the largest production blockchain platform in the world, we share the passion to code, create, and ultimately build an open, accessible and fair financial future, one piece of software at a time.

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.

• You will be responsible for upgrading existing nodes and researching/building/deploying new nodes and validators
• You will create solutions for monitoring and alerting to maximize systems uptime
• You will be creating automation to help with disaster recovery
• You will leverage existing internal SRE best practices to make coin node provisioning and maintenance more efficient and minimize fragmentation with the rest of the ecosystem
• You will develop new tooling in conjunction with the SRE team to be adopted by the rest of the engineering organization where appropriate
• You will be close to our CI/CD pipelines and will be responsible for upgrading and making them more robust/autonomous
• You will play a critical role in evolving our infrastructure as we develop solutions to complex technical problems involving reliability, latency, bandwidth and most importantly security.
• You will focus heavily on writing tooling to replace manual, repetitive work in a scalable way.

WHAT YOU WILL NEED

• Understanding of blockchain consensus mechanics (PoW/PoS, slashing, jailing)  
• Ability to adopt new technologies 
• Experience with monitoring: Grafana, InfluxDB, Prometheus, or similar.

• 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.
