In this fully onsite role, you will be a hands-on technical leader for a small, fast-moving program team supporting a classified space portfolio. You will drive DevSecOps practices across multiple projects, architect secure-by-design solutions, and build and maintain robust CI/CD pipelines and infrastructure that meet stringent mission and security requirements. This role is ideal for a self-starter who is comfortable leading, coding, automating, and collaborating across engineering, cybersecurity, and operations teams.

What You’ll Be Doing:

• Lead DevSecOps initiatives across multiple enclaves and projects, serving as a primary technical point of contact for secure software and infrastructure delivery

• Architect, implement, and maintain secure cloud and on-prem environments using Infrastructure as Code toolsets such as Terraform, Ansible, CloudFormation, or Pulumi

• Establish and maintain observability capabilities (logging, metrics, tracing, alerting) to support reliability, incident response, and performance monitoring for mission systems

• Identify, prioritize, and drive remediation of vulnerabilities across applications, containers, hosts, and infrastructure, in alignment with NIST controls and DoD DevSecOps guidance

• Implement and maintain DAST and SAST tools in coordination with ISSOs, system security engineers, and development teams to support RMF Assessment and Authorization (A&A) efforts and continuous monitoring

• Utilize and manage binary registries (e.g., Artifactory, Harbor, Docker Registry, Nexus) and package repositories in secure environments, ensuring compliance with program policies and security baselines

• Support and enhance compliance- and policy-as-code solutions (e.g., OPA, Conftest, Checkov) to enforce security baselines, configuration standards, and deployment guardrails across Kubernetes, cloud, and IaC artifacts

• Collaborate with systems engineering, cybersecurity, operations, and vendor teams to ensure software and infrastructure designs meet security, performance, availability, and accreditation requirements

• Support and contribute to program documentation and security artifacts, including architecture and deployment documentation, security plans, DevSecOps process documentation, and material for technical reviews and readiness events

• Work with Product Owners and Scrum Masters to translate security and DevSecOps requirements into actionable user stories and tasks; support Agile ceremonies and iterative delivery of secure capabilities

• Drive continuous improvement in automation, tooling, and processes to increase deployment frequency, reduce change failure rates, and strengthen the overall security posture of the program

What Required Skills You’ll Bring:

• Active DoD Secret clearance, with ability and willingness to obtain/maintain TS/SCI

• 10+ years of experience, with additional education, training, and certifications able to count towards total years of experience.

• Bachelor’s degree, or additional years of experience in lieu of a degree

• Proficiency in at least one major programming language (e.g., Java, C#, Python, Go, JavaScript/TypeScript) and associated frameworks, plus Git-based workflows and collaboration tools

• Hands-on experience with containers and orchestration (Kubernetes with RKE2, OpenShift, or Rancher) and managing binary/container registries (Artifactory, Docker Registry, Harbor, Nexus)

• Expertise in DevOps/DevSecOps practices: CI/CD pipeline design and operation, integrating security controls (SAST, DAST, SCA, container scanning, secret management), and secure SDLC implementation

• Advanced Infrastructure as Code and cloud skills: Terraform, Ansible, CloudFormation, Pulumi; building and managing AWS/Azure/GCP environments with monitoring/observability

• Experience with policy-as-code and compliance-as-code solutions (e.g., OPA, Conftest, Checkov)

What Desired Skills You Might Bring:

• Prior experience supporting classified space or defense programs

• Familiarity with Model-Based Systems Engineering (MBSE) tools and methods

• Experience with systems engineering processes, including requirements analysis, design, integration, verification, and validation

• Experience with configuration management and maintaining traceability between software baselines, infrastructure code, and DevSecOps artifacts

• Experience with test automation and GitLab CI/CD or similar CI/CD platforms

• Experience supporting AI/ML application infrastructure and associated data pipelines in secure environments

• Experience with virtualized hosts and platforms (e.g., VMware)

• Basic network understanding and diagnostics, including TCP/IP, routing, firewalls, and VPNs
