This role is instrumental in fortifying mission-critical systems and ensuring compliance with Department of War (DoW) cybersecurity mandates. You will serve as a technical expert, using secure development practices and delivering continuous improvement across our CI/CD ecosystem.

• You will evolve secure CI/CD pipelines by integrating and automating security tools such as SAST, DAST, SCA, and container scanning to meet DoW requirements and reduce operational risk. You will continuously enhance DevSecOps pipelines by refining vulnerability detection thresholds, tuning scanners, reducing false positives, and optimizing remediation workflows. You will harden infrastructure-as-code (IaC) templates, including Terraform, and enforce policy-as-code across environments. You will conduct risk assessments and contribute to system security plans (SSPs) and continuous ATO efforts.

• You’ll collaborate with development, operations, and security teams to support secure software delivery. You’ll monitor pipeline activity for anomalies and assist in responding to security incidents. You will champion zero trust principles and drive adoption across the SDLC. Qualifications

• 5+ years of experience in cybersecurity engineering, including with DevSecOps in federal or defense environments employing IaC/CaC, CI/CD, and SDLC concepts

• 3+ years of experience in software engineering using Python, Typescript, or Bash and automation frameworks

• Strong understanding of security within AWS environments

• Experience implementing or integrating security tooling into cloud environments and/or CI/CD pipelines

• NIST SP 800-53 knowledge and experience working with its security controls

• Experience working within regulated/compliance-driven environments Nice to Have Skills

• Experience reviewing code samples and applying whitelisting or exemption processes

• Experience developing Zero Trust security solutions for DevSecOps pipelines

• Experience evaluating security tools and assessing fit for inclusion in Development or Operational environments

• Knowledge of GRC engineering practices, including policy-as-code implementation, automated compliance validation, continuous control monitoring, security control mapping such as NIST 800-53, RMF, or CIS, risk assessment automation, POA&M management, audit evidence collection, compliance reporting, and integration of GRC requirements into CI/CD and DevSecOps workflows

• Possession of excellent verbal, technical writing, and documentation skills
