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).
