Senior Security Architect

About Us

At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. But our company is more than datasets, lines of code or A/B tests. We’re the thrill of the first night in a new place. The excitement of the next morning. The friends you encounter. The journeys you take. The sights you see. And the memories you make. Through our products, partners and people, we make it easier for everyone to experience the world.

Role Description

The Senior Security Architect exists to make it easier for engineers to build secure, resilient systems without slowing delivery down. Reporting to the Director of Architecture, the role leads the security architecture domain within Tech Standards.

Tech Standards is the central architecture capability that turns Booking.com's enterprise architecture direction into practical principles, guidance, sensible defaults, and reusable patterns. Its purpose is to reduce cognitive load for engineering teams, make good technical choices easier to apply, and help Business Units move faster with confidence.

The role works closely with Security, SRE, Business Unit architects, and engineering teams to ensure security expectations are clear, actionable, and embedded into how software is designed, built, and run. It is not a gatekeeper role. It is an enablement role, focused on making secure engineering the default path.

A core part of the role is helping define the security non-functional requirements that form part of Booking.com's architecture guidance, in close partnership with the Security organisation. Success depends on combining deep security architecture expertise with the ability to influence senior technical communities, make trade-offs clear, and help teams adopt better security practices in real delivery work.
