What this role is

This role focuses on embedding security directly into Expedia's development processes rather than adding it afterward, managing security tools across CI/CD pipelines, and helping engineers ship faster without compromising protection. It suits experienced security engineers who want to bridge development and security teams and have hands-on expertise with modern tooling and cloud practices.
