• DevSecOps & Automation: Lead CI/CD, Infrastructure as Code (IaC) and Configuration as Code (CaC) pipelines, platform automation, onboarding workflows and environment lifecycle management
• Platform Operations & Resilience: Deliver high availability, scalability, monitoring/observability, cost optimization, license management and environment reliability across multiple enclaves and mission threads
• Integration with Enterprise Architecture, Data & MBSE: Work closely with MBSE, data fabric and EA teams to ensure platform services support Digital Threads, automated data pipelines, authoritative data stores and model-driven execution
• Security & Accreditation: Partner with ISSO/cyber engineers to enforce JSIG PL3/PL4 compliance, CSfC guidance, enclave boundary controls, OTEL, security, patching and ongoing accreditation workflows.
• Stakeholder & Vendor Coordination: Collaborate with cross-agency stakeholders, provide technical direction to vendors, resolve integration issues and drive platform capabilities toward enterprise-level interoperability.

• 5+ years' experience leading cloud native platform development and operations.
• Deep experience with Kubernetes orchestration and associated tech stack including service mesh, GitOps, and multi-cloud operations.
• Hands-on experience with IaC/CaC (Terraform, Helm, Dockerfiles), CI/CD (GitLab) and automation pipelines.
• Strong understanding of Zero Trust architectures, identity federation, secrets management, certificate services and policy-as-code.
• Experience operating secure cloud-native environments in classified or high-compliance settings.
• Experience working on Scrum or Agile development team.

Desired Qualifications:
• Experience with Azure Gov, AWS GovCloud, on-prem Kubernetes (Ex: RKE2, NKP) and air-gap management.
• Familiarity with observability stacks (Grafana, Prometheus, OpenTelemetry), hardened container repositories and license servers (FlexLM).
• Experience integrating platform capabilities with enterprise data fabrics, Digital Threads or MBSE environments.
• Experience collaborating with data engineers, MBSE teams, and enterprise architects and Agile/Scrum experience.
• Background supporting DevSecOps in DoD, IC or large-scale engineering ecosystems.
• Strong ability to guide roadmap development, platform governance and enterprise onboarding processes.

Clearance Requirements:
• Must be U.S. citizen with an active TS/SCI clearance and be eligible to obtain a CI Poly.
