Rackner - Application Security Engineer — Secure Mission Systems
Requirements
• At least six years of experience involving cyber resilience, SAST, DAST, and software-vulnerability remediation. • Bachelor’s degree in Cybersecurity. • Hands-on experience identifying, evaluating, and helping resolve application-security vulnerabilities. • Experience working directly with software-development teams to improve secure delivery. • Understanding of secure software-development lifecycle practices and software supply-chain security. • Ability to explain technical security findings clearly to developers and technical stakeholders. • Fortify, X-Ray, OWASP ZAP, or comparable SAST, DAST, dependency, or artifact-scanning tools. • Integrating automated security checks into CI/CD workflows. • GitLab, Artifactory, or similar development and artifact-management environments. • OpenShift, Kubernetes, or other containerized application environments. • Secure-code review and remediation verification. • Supporting classified, defense, or other highly regulated software environments. • Collaborating across application-security, software-engineering, platform, and AI/ML teams.
Responsibilities
• Conduct and support static and dynamic application-security testing. • Use and support automated security scanning with Fortify, X-Ray, OWASP ZAP, and related tools. • Review findings, identify actionable vulnerabilities, and help distinguish meaningful risks from false positives. • Work with software engineers to understand root causes, support remediation, and verify that fixes address identified vulnerabilities. • Help integrate security testing into secure CI/CD and Git-based development workflows. • Strengthen software supply-chain security throughout the development and delivery process. • Contribute to technical reviews, code-review findings, security-remediation reports, and software testing. • Help ensure software meets applicable functional, coding, and security requirements before release.
Benefits
• At Rackner, you will have the opportunity to protect technology supporting critical defense and public-sector missions. • You will work on more than isolated scan execution or vulnerability reports. This role combines hands-on application-security testing, vulnerability analysis, remediation verification, software supply-chain security, and close collaboration across software, AI/ML, platform, and mission-focused teams. • Rackner has delivered more than $30 million in recent federal awards and supports mission-critical work across defense, civilian, and public-sector environments. We are looking for an application-security engineer who can build on that momentum by strengthening secure delivery, helping teams resolve vulnerabilities, and improving confidence in the software reaching mission users. • Competitive compensation • Company-supported certifications aligned with current and future program work • 401(k) with 100% company match up to 6% • Medical, dental, vision, life, and disability coverage • Paid time off and company holidays • Remote-work support and home-office equipment plan • Fitness and wellness reimbursement • Weekly pay schedule • Professional-development and future growth opportunities • If you are an application-security professional who wants broader influence across secure development, automated security testing, vulnerability remediation, and software supply-chain security, we would like to hear from you.
