  web and database servers on AWS (EC2, S3, database services, load balancers), ensuring stability and scalability;

• Management and provisioning of data center and cloud resources using Infrastructure as Code (Puppet/Ansible);

• Contribute to and support the gradual transition towards our internal developer platform (IDP) based on Kubernetes and a shared observability stack, following Git Ops principles;

• The platform teams provide and maintain core infrastructure components such as CI/CD and progressive delivery tooling (Jenkins, ArgoCD), cluster lifecycle, DNS, AWS network, identity and credential/secret management, monitoring, logging and various controllers and operators (e.g. for Ingress, load balancing, DNS, Certificate management and more).
  
  Your role will be focused on migrating, operating, modernising and maturing the web‑services running on top of this platform;

• Ownership of the
  automated build and deployment pipeline (Jenkins);

• Integration with the organization’s observability platform (powered by Prometheus, Grafana, Loki, Ops Genie, Pingdom);

• Ensuring systems are
  patched and aligned with IT security standards
  , including evaluation of updates for compatibility and functional impact;

• Configuration of application‑level routing and SSL/TLS settings using the platform’s ingress and certificate‑management tooling (e.g., Traefik/Istio, cert‑manager, external‑dns);

• Incident investigation and root‑cause analysis
