For more information, visit www.DAT.com Job Application Deadline: 10/31/2026 The Opportunity Security Architecture & Engineering (SAE) is the hands-on engineering arm of DAT's Information Security organization, sitting alongside the Security Operations Center (SOC) and Governance, Risk & Compliance (GRC) teams. SAE owns vulnerability management, cloud and network security, product security (AppSec/DevSecOps), and the security tooling that protects DAT's platforms and customer data. It's a small, high-ownership team - you won't be one of dozens of engineers on a rotation; the work you do has direct, visible impact on how quickly DAT can find, fix, and close out real security risk. What You'll Do

• 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.

What You'll Bring

• 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.
