- Define and enforce secure coding practices, frameworks, and guidelines through codified policies and secure-by-default templates.
- Embed security controls and tooling into DevOps pipelines to enable continuous security validation through infrastructure-as-code and policy-as-code approaches.
- Champion “shift-left” practices ensuring vulnerabilities are identified and remediated early.
- Develop automated solutions for vulnerability detection, dependency management, and compliance monitoring utilizing AI agents and modern automation frameworks.

- Provide input into security risk assessments for new features, integrations, and third-party components.
- Act as a subject matter expert for product security, advising engineering and product teams.
- Lead and mentor security engineers and developers in secure development practices.
- Collaborate with IT, Infrastructure Security, and Risk teams to ensure end-to-end security.
