What You Will Do:

Guidehouse’s Cybersecurity practice partners with federal and regulated clients to engineer secure, resilient applications and delivery pipelines that support mission outcomes at enterprise scale. Our teams integrate security engineering, software development, and DevSecOps automation to embed protection into the full application lifecycle.

As a Senior IS Security Developer, you will lead enterprise secure application development and DevSecOps automation initiatives supporting federal cybersecurity missions. You will define secure development standards, architect scalable automation frameworks, and oversee integration of security controls into CI/CD pipelines across cloud, hybrid, and on‑premises environments. Operating as a technical authority, you will make secure software architecture decisions, validate security testing rigor, and provide executive‑level insight into application security risk posture and remediation strategy.

This role positions you as a senior technical leader in secure software delivery, accountable for embedding security into the application lifecycle and enabling scalable, automated DevSecOps practices that strengthen federal cyber resilience.

Key Responsibilities

• Lead enterprise secure application development and DevSecOps modernization initiatives from strategy and architecture through implementation and operationalization.
• Define and maintain secure software development standards and patterns aligned to NIST RMF and the NIST Secure Software Development Framework (SSDF – SP 800‑218), as well as agency‑specific mandates.
• Architect scalable DevSecOps automation frameworks that embed security controls, policy enforcement, and evidence generation across CI/CD pipelines.
• Oversee integration of application‑layer security controls into build, test, and deployment workflows, including SAST, DAST, IAST, SCA, container and IaC scanning, secret management, and policy‑as‑code.
• Provide technical authority for secure software and application architecture decisions, resolving cross‑domain design issues and approving implementation patterns.
• Validate security testing rigor and coverage, ensuring findings are actionable, prioritized by risk, and effectively remediated.
• Ensure application security controls are mapped to applicable control frameworks (e.g., NIST SP 800‑53) and generate defensible artifacts for authorization and continuous monitoring.
• Lead secure application deployments across cloud (IaaS/PaaS/SaaS), hybrid, and on‑premises environments, accounting for shared responsibility models.
• Establish engineering governance and quality standards, including design reviews, guardrails, reusable pipelines, and architecture decision records.
• Deliver executive‑level reporting on application security risk posture, vulnerability trends, remediation progress, and compliance status.
• Mentor and develop developers, security engineers, and DevSecOps practitioners; conduct technical reviews and promote secure‑by‑design practices.
• Support business development through solution shaping, proposal contributions, and client technical briefings.

What You Will Need:

• Must be able to OBTAIN and MAINTAIN a Federal or DoD "PUBLIC TRUST"; candidates must obtain approved adjudication of their PUBLIC TRUST prior to onboarding with Guidehouse. Candidates with an ACTIVE PUBLIC TRUST or SUITABILITY and maintain an active HHS/NIH clearance are preferred.
• Bachelor’s degree in Cybersecurity, Information Systems, Computer Science, or a related field (additional relevant experience may substitute for formal education).
• Minimum NINE (9) or more years of progressively responsible experience in secure software development, application security engineering, DevSecOps, or related roles.
• Required certifications:
  • CompTIA Security+ (active)
  • CISSP or relevant DevSecOps / cloud developer certifications (e.g., AWS/Azure/GCP Developer or DevOps Engineer, Kubernetes, GitLab/GitHub DevSecOps)
• Demonstrated experience embedding security controls into CI/CD pipelines and automating compliance and evidence collection.
• Strong understanding of secure coding practices, application security testing methods, and modern software architectures (microservices, APIs, containers).
• Experience supporting federal agencies with ATO‑driven DevSecOps or continuous authorization models.
• Working knowledge of federal cybersecurity governance, including RMF, continuous monitoring, and authorization processes.
• Excellent written and verbal communication skills, including experience briefing technical and executive stakeholders.

What Would Be Nice to Have:

• Hands‑on experience with leading CI/CD and security platforms (e.g., GitHub Actions, GitLab CI, Jenkins, Azure DevOps, SonarQube, Snyk, Checkmarx, Prisma Cloud, Aqua).
• Experience implementing policy‑as‑code and control automation using IaC tools (Terraform, CloudFormation, Bicep).
• Additional certifications such as CSSLP, CCSP, CISM, or advanced cloud security credentials.
• Prior consulting experience with responsibility for delivery leadership and client engagement.
