DevOps Engineer- Blockchain Infrastructure

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Dev Ops Engineer – Blockchain Infrastructure based in United Kingdom. Join a cutting-edge blockchain infrastructure team dedicated to building secure, reliable, and scalable systems for privacy-preserving applications. In this hands-on role, you will help operate and scale blockchain networks, manage validator infrastructure, and strengthen the reliability of critical production environments.

You will work across multi-cloud and bare-metal platforms, developing automation and observability solutions that support high availability and performance. Your work will contribute to the evolution of a federated validator model toward a fully decentralised network. Collaborating with engineering teams and infrastructure partners, you will progressively take ownership of day-to-day operations while driving continuous improvements in security, resilience, and deployment efficiency.

This is an opportunity to make a tangible impact in a fast-moving blockchain ecosystem while working with modern infrastructure technologies and open-source tooling.

• Ensure protocol reliability:
  Maintain critical blockchain infrastructure with a target of 99.99% uptime, proactively identify reliability risks, and implement improvements to availability and performance.
• Manage incident response:
  Participate in the on-call rotation, troubleshoot production incidents, resolve operational issues, and document blameless post-mortems to prevent recurrence.
• Operate validator infrastructure:
  Manage, maintain, and automate blockchain validator nodes across multi-cloud and bare-metal environments, ensuring scalability, reliability, and optimal performance.
• Support network decentralisation:
  Contribute to the transition from a foundation-coordinated federated validator model to a fully decentralised network, helping improve onboarding and deployment templates for Foundation Node Operators (FNOs) and future Stake Pool Operators.
• Develop infrastructure tooling:
  Build, maintain, and improve open-source tools that simplify blockchain infrastructure management, deployment, and automation.
• Strengthen security and performance:
  Identify vulnerabilities, improve security controls, investigate infrastructure bottlenecks, and implement solutions that enhance system resilience and efficiency.
• Build deployment pipelines:
  Design, maintain, and optimise secure CI/CD pipelines using Git Hub Actions and other relevant automation tools.
• Improve monitoring and observability:
  Develop telemetry solutions, remote monitoring capabilities, and ETL dashboards that provide actionable insights into infrastructure health and performance.
• Own day-to-day operations:
  Gradually take responsibility for infrastructure management, coordinate with internal engineering teams and external infrastructure partners, and provide technical recommendations and regular operational feedback.
• Troubleshoot and optimise environments:
  Build and configure development, testing, and mainnet environments, resolving deployment issues and protocol-level bottlenecks ahead of network upgrades.
• Drive continuous improvement:
  Take initiative in identifying automation opportunities, documenting infrastructure designs, and improving operational processes across distributed teams.

• Professional experience:
  At least 3 years of hands-on experience in Dev Ops, Site Reliability Engineering (SRE), or infrastructure engineering, including at least 1 year working with blockchain infrastructure.
• Blockchain expertise:
  Practical experience operating blockchain nodes, validator infrastructure, or comparable distributed systems in production environments.
