• Own the design, build, and operations of a modular, API‑first platform that abstracts infrastructure from simulation software.
• Lead multi‑cluster Kubernetes, service mesh, security hardening, and observability to support hundreds of users and tens of thousands of entities across connected and air‑gapped environments.
• Design and operate multi‑cluster Kubernetes environments (control/data/CI/observability planes) with strong isolation and zero‑trust defaults.
• Implement service mesh (e.g., Istio) for mTLS, traffic control, and fine‑grained Authorization Policy; manage ingress (Gateway/Virtual Service) and east‑west policies.
• Author and maintain platform CRDs and controllers/operators to reconcile developer intent into runtime objects (name spaces/cells, Deployments/Jobs, Services, policies, gateways).
• Integrate network policy (eBPF/Cilium), secrets management, RBAC/ABAC, and policy‑driven automation across environments.
• Stand up observability (metrics/logs/traces) and SLO monitoring; drive reliability (HA, backup/restore, DR).

• Controller/operator development using Go (Kubebuilder/Operator SDK) or Type Script‑based frameworks; CRD design/versioning.
• Observability:
  Prometheus, Open Telemetry, Fluent Bit/Open Search; incident response and performance tuning.
• Security: mTLS, OIDC, JWT, OPA/Gatekeeper/Kyverno (or equivalent), image signing, SBOM, CVE remediations.

• Experience in air‑gapped or classified environments; package and deploy with tools that support disconnected sites.
• Exposure to Kubernetes Gateway/Envoy Gateway, egress control, and sidecar injection strategies.
• Prior VV& A support for modeling & simulation platforms.
• Ability to work across Unclassified → Secret → TS/SCI/SAP environments.
