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 onpremises environments. Operating as a technical authority, you will make secure software architecture decisions, validate security testing rigor, and provide executivelevel 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 agencyspecific mandates.
- Architect scalable DevSecOps automation frameworks that embed security controls, policy enforcement, and evidence generation across CI/CD pipelines.
- Oversee integration of applicationlayer security controls into build, test, and deployment workflows, including SAST, DAST, IAST, SCA, container and IaC scanning, secret management, and policyascode.
- Provide technical authority for secure software and application architecture decisions, resolving crossdomain 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 onpremises environments, accounting for shared responsibility models.
- Establish engineering governance and quality standards, including design reviews, guardrails, reusable pipelines, and architecture decision records.
- Deliver executivelevel 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 securebydesign practices.
- Support business development through solution shaping, proposal contributions, and client technical briefings.
