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. This 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.

What you'll do

• 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.

What you bring

• 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.
• Knowledge of cloud security practices, IAM, networking, and secrets management.

Nice to have

• Experience with blockchain infrastructure or Web3 platforms.
• Experience deploying or managing blockchain nodes such as Ethereum, Bitcoin, Solana, Cosmos, or other Layer 1 and Layer 2 networks.
• Familiarity with blockchain RPC services, validators, indexing platforms, or distributed consensus systems.
• Experience with Argo CD, Helm, Helmfile, or Flux.
• Experience with service mesh technologies such as Istio or Linkerd.
• Familiarity with message queues, distributed caching, and high-throughput systems.
• Experience with cryptocurrency exchanges, blockchain infrastructure providers, or large-scale distributed platforms.
• Experience contributing to open-source projects.
