- Assist with configuring and maintaining security scanning tools used during development, build, test, release, and runtime activities.
- Document, track, and validate vulnerabilities
- Document, triage, track, and validate vulnerabilities and security findings through remediation and closure.
- Maintain accurate vulnerability status, remediation evidence, and closure documentation.
- Assist development teams with secure coding and remediation
- Provide technical guidance to development teams on secure coding practices and remediation of identified weaknesses.
- Help teams understand scan results, vulnerable dependency reports, policy violations, and recommended fixes.
- Support DevSecOps tool integration and automation
- Support integration and operation of security tools and controls within CI/CD pipelines.
- Help implement automated security gates, policy enforcement, and reporting workflows.
- Integrate DevSecOps tools through APIs to improve visibility, automation, and operational efficiency.
- Develop proof-of-concept secure reference implementations
- Design and develop proof-of-concept sample applications using common technology stacks to demonstrate application security best practices.
- Build reference examples that illustrate secure authentication, authorization, logging, dependency management, secrets handling, containerization, API security, and secure CI/CD workflows.
- Maintain reusable patterns and examples that development teams can reference when implementing security controls.
- Ideate and develop security utility applications
- Identify process and technology gaps between development and security teams.
- Design and develop utility applications, scripts, dashboards, integrations, or automation workflows that improve vulnerability management, reporting, remediation tracking, tool interoperability, and DevSecOps operations.
- Integrate with security, development, repository, observability, and CI/CD tools through available API interfaces.
- Monitor compliance with application security standards
- Monitor security findings and alignment with established application security standards and controls.
- Support security improvement initiatives aligned to Zero Trust principles and applicable NIST, CISA, and CIS security frameworks.
- Collect metrics, evidence, and reporting data
- Collect and maintain security assessment data, scan results, vulnerability evidence, remediation status, and operational metrics.
- Support reporting for continuous monitoring, vulnerability reduction, and application security improvement initiatives.
- Support DevSecOps and vulnerability reduction initiatives
- Support enterprise DevSecOps, vulnerability reduction, secure software development, and application security modernization efforts across USCIS programs.
Requirements:
- Bachelor’s degree in Information Technology, Computer Science, Cybersecurity, Engineering, or a related field.
- Minimum of 4 years of professional IT experience, plus 4 years of experience supporting application security, cybersecurity, DevSecOps, or closely related subject matter requirements.
- Advanced technical knowledge of application security technologies, specialized applications, and operational environments.
- Experience performing technical and functional analysis, system integration, implementation, documentation, and technical guidance for complex application security or DevSecOps initiatives.
- Experience with application security testing and vulnerability assessment.
- Experience with secure coding practices and providing remediation guidance to development teams.
- Experience with static application security testing (SAST), dynamic application security testing (DAST), software composition analysis (SCA), container scanning, and dependency security.
- Experience integrating security controls and tools into CI/CD pipelines and DevSecOps workflows.
- Experience developing proof-of-concept applications, secure reference implementations, utility applications, scripts, dashboards, or API-based integrations.
- Experience with vulnerability management workflows, including triage, documentation, remediation tracking, validation, and closure.
- Knowledge of application security frameworks and guidance, including Zero Trust, NIST, CISA, CIS, OWASP, and secure software development lifecycle practices.
- Experience working collaboratively with development, security, platform, operations, and other technical teams.
Preferred Qualifications:
The ideal candidate can:
- Review and interpret security scan results from tools such as SonarQube, Nexus IQ, Checkmarx, and Twistlock.
- Configure and support Nexus Repository Firewall policies and dependency blocking workflows.
- Analyze CVEs, CVSS scores, vulnerable dependency paths, and recommended component versions.
- Build simple proof-of-concept applications in common technology stacks such as Java/Spring Boot, Node.js, Python, Ruby, or .NET.
- Create automation scripts or utility applications using APIs from DevSecOps tools.
- Develop integrations that collect, normalize, and report security findings from multiple tools.
- Support Kubernetes and container security practices.
- Use Splunk and New Relic data to support application security monitoring and operational visibility.
- Work with Harness or similar CI/CD platforms to support security scanning and deployment controls.
- Translate security framework requirements into practical application security practices.
