Senior Site Reliability Engineer I

Our mission at Booking.com is to create transformative, innovative, and personalised travel experiences for millions of customers all across the world. We want customers to have an amazing experience wherever and whenever they choose: mobile, web, and through partners and 3rd parties.

About the team - Private cloud:

The Private Cloud group operates, orchestrates, and optimizes Booking-managed cloud infrastructure. The Private Cloud capabilities are provided on platform instances that are privately owned and centrally managed by Booking.com. These platform instances, and the workloads running on them, are hosted both in Booking data centers (“on-premises”) and on public cloud infrastructure (AWS).

The Private Cloud platform has three primary internal customer-facing verticals: virtualisation, containerisation, and server-less, corresponding to the three types of workloads it supports.

At the highest level, the Booking Private Cloud drives three primary business outcomes:

• Agility in provisioning and using cloud infrastructure.
• Efficiency in cost and utilisation of cloud infrastructure, as well as toil reduction for developers and engineers.
• Trust in the safety, reliability, and performance of our cloud infrastructure.
