Responsibilities

• Develop and operate infrastructure in GCP, including GKE, virtual machines, networking, load balancers, storage, and managed services
• Manage Infrastructure as Code with Terraform: develop modules, manage state and dependencies, ensure reproducible changes, and identify configuration drift
• Operate Kubernetes: upgrade clusters and platform components, configure autoscaling, workload placement, network policies, and resource allocation
• Develop CI/CD and GitOps using GitLab CI and Flux / Argo CD, automating builds, checks, deployments, controlled releases, and rollbacks
• Build observability across metrics, logs, distributed tracing, and actionable alerting. Define and improve SLIs/SLOstogether with engineering teams
• Troubleshoot production incidents and performance issues, conduct root cause analysis, and eliminate recurring failure patterns
• Implement least-privilege access, environment and service isolation, secure secrets management and rotation, and infrastructure audit controls
• Maintain backup processes and regularly validate recovery of critical data and infrastructure according to agreed RPO/RTO
• Help engineering teams prepare services for production, including health checks, resource configuration, telemetry, and deployment procedures
• Optimize cloud infrastructure usage and costs while maintaining reliability requirements
• Maintain infrastructure documentation, operational runbooks, and recovery procedures
  
  

Requirements

• Strong hands-on experience independently operating production infrastructure and Kubernetes, including upgrades, troubleshooting, and disaster recovery
• Strong experience with GCP, including GKE, Compute Engine, VPC, IAM, and Cloud Storage; good understanding of Cloud SQL, Cloud Logging, and Cloud Monitoring
• Hands-on experience with Terraform, including modules, remote state, locking, importing existing resources, and safely applying infrastructure changes through CI
• Deep knowledge of Kubernetes and containerization: Deployments, StatefulSets, Services, Ingress, storage, requests/limits, probes, autoscaling, RBAC, and NetworkPolicy
• Experience with Helm and Kustomize
• Strong Linux administration skills, preferably Debian/Ubuntu: processes, systemd, filesystems, disks, and resource troubleshooting
• Strong networking fundamentals: TCP/IP, DNS, HTTP(S), TLS, routing, NAT, load balancing, and firewalls
• Ability to troubleshoot connectivity issues across applications, Kubernetes clusters, networks, and cloud services
• Experience building CI/CD pipelines, preferably with GitLab CI, and strong understanding of Git and GitOps principles
• Understanding of runner permissions, secrets protection, and production deployment controls
• Automation skills with Bash and Python, including maintainable infrastructure scripts and API integrations
• Experience with monitoring, logging, and alerting using tools such as Prometheus, Grafana, or Cloud Monitoring
• Practical experience operating PostgreSQL and understanding Redis and RabbitMQ, including availability, connections, replication or clustering, backup, and recovery
• Strong understanding of cloud security principles: least privilege, service accounts, Workload Identity, secrets management, network segmentation, and access auditing
• Ability to independently deliver infrastructure changes to a validated production result, explain technical trade-offs, and collaborate effectively with Engineering and Security teams
