We’re expanding our Kubernetes-backed containerization and orchestration platform and seeking a Software Engineer who is passionate about building secure, scalable, and automated capabilities end-to-end. You’ll own features across the full development lifecycle—from design and development to deployment and operations—while enforcing strong security guardrails and enabling efficient multi-tenant workload isolation. This role is ideal for engineers who enjoy working close to the platform, automating everything, and turning complex operational requirements into elegant, repeatable solutions. TS/SCI with current Full-Scope Polygraph (required)

Requirements

• Bachelor’s degree in Computer Science, Computer Engineering, or closely related field; or equivalent practical experience.
• Full development lifecycle experience delivering capabilities on Kubernetes (design, build, test, deploy, operate).
• Hands-on experience building and maintaining custom Kubernetes Helm charts or an equivalent resource manager (e.g., Kustomize ).
• Proven expertise with Kubernetes RBAC policy configuration and enforcement.
• Practical use of namespaces to separate and manage workloads.
• Experience configuring granular workload permissions using native roles and role bindings .
• Experience building automation pipelines (CI/CD) that interface directly with Kubernetes orchestration (e.g., GitOps , progressive delivery).
• Active TS/SCI with polygraph required Day 1
• U.S. citizenship required due to clearance requirements.

Nice To Haves

• Experience developing custom Kubernetes controllers , including mutating and validating admission webhooks to enforce policy and standardization.

• Experience defining custom Kubernetes-native network policies (CNI) for zero-trust segmentation.
• Track record managing multiple, isolated tenants within a single Kubernetes environment.
• Experience generating and collecting workload metrics using standard endpoints (e.g., Prometheus, OpenMetrics ) and exposing health probes.
• Integration of Kubernetes workloads with AWS cloud-native services using IAM role permissions (e.g., IRSA, service account <-> role mapping).

Responsibilities

• Design & build new capabilities for our Kubernetes platform, including container orchestration workflows, deployment tooling, and operational automation.
• Develop and maintain custom Helm charts (or equivalent Kubernetes resource management artifacts) for repeatable, compliant deployments across environments.
• Implement and enforce Kubernetes RBAC security policies, native roles, and role bindings for least-privilege access and granular workload isolation.
• Leverage namespaces to segment workloads and align tenancy, compliance, and operational boundaries.
• Integrate CI/CD pipelines with Kubernetes orchestration to automate build, test, deploy, and rollback processes.
• Instrument workloads and platform components with metrics, health checks, and standardized endpoints to improve observability and SLO adherence.
• Collaborate cross-functionally with security, cloud, networking, and application teams to ensure platform capabilities meet mission needs.
• Document architecture, patterns, runbooks, and guardrails to drive consistency and enable self-service.
