  • Own software security for the cyber engineering team, offering technical guidance for securing applications, APIs, and back-end services.
  • Perform security testing of applications and validate that fixes resolve identified findings.
  • Review source code against secure coding standards to identify vulnerabilities, insecure design, and exploitable weaknesses.
  • Implement, tune, and maintain software security tools, including SAST, DAST, dependency scanning, and container scanning, and integrate them into development and release workflows.
  • Evaluate open-source and commercial cyber tools and source code to determine security risk, fit, and mission adaptability.
  • Partner with engineers, system admins, architects, ISSOs, and ISSMs to define security requirements and confirm that tools and controls are sufficient.
  • Assess risk associated with major software changes, unpatched components, and software reaching end of support.
  • Apply adversary techniques (including MITRE ATT&CK) and threat modeling to prioritize findings based on real-world impact.

Required Qualifications

  • BS degree in Computer Science, Software Engineering, Computer Information Systems, Cybersecurity, or a related field (experience may substitute for degree).
  • TS/SCI Clearance.
  • CompTIA Security+ (DoD 8140 compliant).
  • Minimum 5 years of combined experience in software development, application security, penetration testing, or secure software assessment.
  • Hands-on software development experience in at least one language such as Python, Java, C#, Go, or JavaScript, with understanding of back-end services, APIs, and databases.
  • Demonstrated experience identifying and validating software vulnerabilities via code review, security testing, or technical assessment.
  • Working knowledge of common application weaknesses (OWASP Top 10, CWE), how they are exploited, and how to remediate them.
  • Ability to assess exploitability and impact, and communicate clear, practical fixes to engineers and compliance staff.
  • Ability to work independently as the primary software security resource on a cybersecurity team.
