Team Lead DevOps (Platform Team)

Ajax Systems, an international tech company and the largest manufacturer of security systems in Europe.

We are looking for a DevOps Team Lead to join our Platform Team and help us scale, secure, and improve our cloud infrastructure. This role combines hands-on technical ownership with team leadership: you will guide DevOps engineers, define platform priorities, improve reliability, and collaborate closely with product and engineering teams.

The System Division develops the Ajax software ecosystem — including OS Malevich, the Video Management System, cloud infrastructure, and client applications. The team ensures the stable operation of all system components as a unified digital platform.

• 5+ years of experience in DevOps, Platform Engineering, SRE, or Cloud Engineering, including 2+ years in a lead or senior ownership role.

• Strong hands-on experience with Kubernetes, preferably AWS EKS, including cluster operations, networking, autoscaling, workload reliability, and security best practices.
  Solid AWS experience: VPC, IAM, EC2, RDS, ElastiCache, Route 53, Lambda, Load Balancers, CloudFront/S3 etc.

• Experience with Infrastructure as Code and configuration management tools, especially Terraform/Terragrunt.

• Experience with GitOps-based delivery using Argo CD or Flux, and Helm/Kustomize for Kubernetes application management.

• Strong Linux and TCP/IP networking knowledge, including troubleshooting production systems.

• Experience with secrets management, access control, and credential rotation practices.

• Strong observability background: metrics, logs, alerts, SLOs, incident investigation, and tools such as Datadog, Grafana, VictoriaMetrics, ELK, or Opsgenie.

• Ability to lead technical discussions, explain trade-offs, set priorities, and drive decisions across engineering teams.
  Strong communication, ownership, task management, and mentoring skills.
  
  

• Experience with advanced Kubernetes tooling: Karpenter, KEDA, Envoy, Istio/Linkerd or similar.

• Experience with streaming platforms such as NATS or Kafka.

• Operational experience with databases such as MongoDB, MySQL, PostgreSQL, or managed cloud database services.

• Experience with compliance frameworks such as SOC 2.
  Background in FinOps, cloud cost optimization, and infrastructure efficiency improvements.

• Experience with disaster recovery planning, backup strategies, incident response, or production fire drills.
