- Maintain and improve core platform services including identity, ingress, observability, certificate management, service mesh and container registry capabilities.
- Build and operate observability across logs, metrics, traces, alerting, SLOs and error budgets.
- Improve platform hardening in line with secure and regulated environment requirements, including network policy, SELinux, image provenance, secret management and audit.
- Automate repeatable operational tasks using tools such as Ansible, Terraform, Helm, Kustomize, Go, Python or equivalent technologies.
- Lead incident response activity, support blameless post-mortems and drive systemic fixes.
- Partner with networking and security teams on platform integration, segmentation, load balancing and accreditation evidence.
