About the role

  • 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 AuthorizationPolicy; manage ingress (Gateway/VirtualService) and east‑west policies
  • Author and maintain platform CRDs and controllers/operators to reconcile developer intent into runtime objects (namespaces/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)
  • Support air‑gap packaging/delivery and secure software supply chain (images, SBOMs, provenance)

Requirements

  • 12+ years of Software Engineering experience
  • 5–8+ years in platform/SRE roles operating production Kubernetes at scale
  • Strong multi‑cluster and GitOps (Argo CD/Flux) experience
  • Hands‑on with Istio/Envoy, Cilium (NetworkPolicy, eBPF), Ingress/Gateway API, and cluster networking (DNS, L7/L4)
  • Controller/operator development using Go (Kubebuilder/Operator SDK) or TypeScript‑based frameworks; CRD design/versioning
  • Observability: Prometheus, OpenTelemetry, Fluent Bit/OpenSearch; incident response and performance tuning
  • Security: mTLS, OIDC, JWT, OPA/Gatekeeper/Kyverno (or equivalent), image signing, SBOM, CVE remediations
Benefits
  • 401K plan with company match
  • Medical, dental, vision, life insurance
  • AD&D
  • Flexible spending account
  • Disability
  • Paid time off
  • Flexible work schedule
