Job description

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a DevOps Engineer – Blockchain Infrastructure based in Spain.

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.

Accountabilities

• 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 GitHub 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.

Requirements:

• Professional experience: At least 3 years of hands‑on experience in DevOps, 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.

• Linux and containers: Strong Linux administration skills and working knowledge of containerisation technologies and Kubernetes.

• Monitoring and observability: Experience with Grafana, Prometheus, or similar monitoring and observability platforms.

• Scripting and programming: Strong shell scripting skills, with working knowledge of at least one programming language such as Rust, Go, or Python.

• Cloud infrastructure: Experience configuring, scaling, and optimising cloud environments, ideally using AWS and Google Cloud.

• Infrastructure as Code: Practical experience with Infrastructure as Code (IaC) tools such as Terraform and/or OpenTofu.

• CI/CD and automation: Experience building and maintaining automated delivery pipelines using GitHub Actions, Jenkins, or equivalent tools.

• Security and reliability: A solid understanding of infrastructure security principles, vulnerability management, system resilience, and performance optimisation.

• Communication and documentation: Ability to communicate technical concepts clearly, document infrastructure architectures, and provide actionable recommendations to internal and external stakeholders.

• Autonomy and problem-solving: A proactive, hands‑on approach, with the ability to work independently, take ownership of technical challenges, and deliver practical solutions in a fast‑moving environment.

• Remote collaboration: Ability to work remotely from an eligible location in Asia, Europe, or Latin America, with 1–2 hours of daily overlap with US or EU time zones.

• Schedule flexibility: Willingness to work a flexible schedule, following either a Sunday–Thursday or Tuesday–Saturday pattern, and participate in an on‑call rotation.

• Nice to have: Experience with GitOps, Nix, or working in a small, fast‑paced technology company.

Benefits:

• Remote work: Work remotely from an eligible location in Asia, Europe, or Latin America, subject to the role's location and availability requirements.

• Flexible working arrangements: Choose between Sunday–Thursday or Tuesday–Saturday schedules, with 1–2 hours of daily overlap with US or EU time zones.

• Meaningful technical impact: Help build and maintain the infrastructure powering privacy‑preserving blockchain applications and contribute to the development of a decentralised validator network.

• Modern technology environment: Work with multi‑cloud and bare‑metal infrastructure, blockchain validator operations, open‑source tooling, automation, and observability technologies.

• Ownership and autonomy: Take increasing responsibility for infrastructure operations, technical decisions, and continuous improvement initiatives.

• Cross-functional collaboration: Work closely with engineering teams and infrastructure specialists on reliability, security, and network scalability.

• Professional development: Expand your expertise in blockchain infrastructure, distributed systems, cloud engineering, and decentralised network operations.

• Employment type: Full‑time, mid-level position.
