## About the Role

* 2-4 years of experience in a security engineering, DevSecOps, or closely related infrastructure/engineering role.
 * Working knowledge of cloud security fundamentals, ideally AWS (IAM, network security groups, logging/monitoring).
 * Hands-on experience with vulnerability management tools and processes - finding, triaging, and driving remediation, not just reporting.
 * Comfort reading and writing code or scripts (Python, Bash, or similar) to automate security tooling and workflows.
 * Ability to work cross-functionally with engineering teams and communicate security risk in terms they can act on.
 * Willingness to participate in an on-call rotation for security incidents.

Bonus Skills

 * Experience with any of DAT's current security stack: CrowdStrike, GitHub Advanced Security (GHAS), SonarCloud, Cloudflare WAF, Auth0, or Torq.
 * A security certification such as Security+, GSEC, or an AWS security certification.
 * Prior experience on a lean security team where engineers own broad scope rather than a narrow specialty.
 * Familiarity with SOX or similar compliance-driven environments.

## Description

* Vulnerability remediation - own and drive vulnerabilities identified through DAT's scanning and monitoring stack (including GitHub Advanced Security and cloud security tooling) through to closure against defined SLAs.
 * Incident response - participate in the security on-call rotation and serve as a technical responder during active security incidents, following DAT's incident response runbooks.
 * Secure design review - review architecture and feature designs from engineering teams for security risk as part of DAT's Secure Design Review process, before code ships.
 * Security tooling - maintain and improve the tools that make security scale, including WAF, endpoint protection, vulnerability scanning, and SIEM/alerting integrations.
 * Cloud & network security - contribute to ongoing cloud security hardening and Zero Trust network initiatives across DAT's AWS environment.
 * Cross-team partnership - work directly with product and engineering teams to close security exceptions, remediate findings, and build security into their workflows - without owning their roadmap.
