DevOps Engineer, Blockchain Infra

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a DevOps Engineer, Blockchain Infra based in Ireland.

Join a global infrastructure team building highly available, scalable, and secure platforms for blockchain services and distributed systems. You’ll design and operate cloud-native infrastructure across multiple major cloud providers while improving reliability and automation at scale. The role combines DevOps, SRE, software engineering, and platform engineering responsibilities in a technically demanding environment. You’ll work extensively with Kubernetes, Terraform, CI/CD, observability, and distributed middleware while supporting production-critical services. Your work will directly influence deployment speed, platform resilience, security, and developer experience. This is an opportunity to solve complex infrastructure challenges while contributing to systems operating at global scale.

Accountabilities:

As a DevOps Engineer focused on blockchain infrastructure, you’ll own critical elements of cloud infrastructure and platform reliability, partnering closely with engineering teams to build resilient and efficient production environments.

• Design, build, and maintain highly available cloud infrastructure across AWS, GCP, and Azure.
• Operate, optimize, and scale Kubernetes clusters in production environments.
• Manage Kubernetes autoscaling and node lifecycle using Karpenter and native Kubernetes capabilities.
• Build and maintain Infrastructure as Code using Terraform.
• Design, improve, and maintain CI/CD pipelines for application and infrastructure deployments.
• Deploy and operate middleware platforms including Kafka, Redis, and NGINX.
• Automate operational workflows and infrastructure tasks using Golang and Python.
• Improve platform observability through monitoring, logging, alerting, and distributed tracing.
• Ensure infrastructure meets high standards for reliability, scalability, security, and disaster recovery.
• Troubleshoot production incidents, conduct root cause analysis, and implement preventative improvements.
• Partner with software engineers to improve deployment processes, infrastructure tooling, and developer experience.
• Participate in on-call rotations and incident response activities.
• Support multi-region and multi-cloud infrastructure where required.
• Contribute to capacity planning and performance optimization for large-scale distributed systems.

Requirements:

You’ll be a strong fit if you have solid DevOps or SRE experience, strong cloud and Kubernetes expertise, and an interest in operating infrastructure for blockchain and distributed systems.

• 3+ years of professional experience as a DevOps Engineer, Platform Engineer, Site Reliability Engineer, or Infrastructure Engineer.
• Strong hands-on experience with at least one major cloud platform, such as AWS, GCP, or Azure.
• Proven experience managing Kubernetes environments in production.
• Practical experience with Karpenter for Kubernetes autoscaling and node lifecycle management.
• Strong experience with Terraform and Infrastructure as Code practices.
• Solid Linux administration and networking fundamentals.
• Experience operating middleware technologies such as Kafka, Redis, and NGINX.
• Strong scripting and programming capabilities using Golang and/or Python.
• Experience with Git, GitOps workflows, and CI/CD platforms.
• Strong understanding of observability technologies such as Prometheus and OpenTelemetry.
• Familiarity with Docker and container-based infrastructure.
• Strong troubleshooting, analytical, and problem-solving skills.
• Experience with blockchain infrastructure or Web3 platforms is highly advantageous.
• Experience deploying or managing blockchain nodes such as Ethereum, Bitcoin, Solana, Cosmos, or other Layer 1 and Layer 2 networks is a plus.
• Familiarity with blockchain RPC services, validators, indexing platforms, or distributed consensus systems is beneficial.
• Experience with Argo CD, Helm, Helmfile, or Flux is advantageous.
• Knowledge of cloud security practices, IAM, networking, and secrets management.
• Experience with service mesh technologies such as Istio or Linkerd is a plus.
• Familiarity with message queues, distributed caching, and high-throughput systems is beneficial.
• Experience with cryptocurrency exchanges, blockchain infrastructure providers, or large-scale distributed platforms is a strong advantage.
• Experience contributing to open-source projects is a plus.

Benefits:

• Competitive salary and company benefits.
• Work-from-home arrangement, with the specific setup potentially varying according to business and team requirements.
• Opportunity to work on large-scale blockchain and distributed infrastructure.
• Exposure to AWS, GCP, Azure, Kubernetes, Terraform, and modern platform engineering technologies.
• Opportunity to contribute to multi-region and multi-cloud production environments.
• Collaboration with highly skilled international engineering and infrastructure professionals.
• Flat, user-focused organisational structure with significant autonomy.
• Fast-paced environment focused on technically challenging projects and measurable results.
• Career growth and continuous learning opportunities.
• Opportunity to contribute to the development of global blockchain infrastructure and Web3 technologies.
