** WHY THIS ROLE IS IMPORTANT TO US
** We are looking for a Senior Cyber Defense Engineer who wants to be in a technical role. Someone who is comfortable going both wide and deep across our Azure security landscape.

You won’t be siloed into a single area. Instead, you will play a key role across the end to end security lifecycle—shaping strategy, driving initiatives, and contributing deep expertise — from building efficient detections in Sentinel and managing incident response to designing the logging strategies that make our monitoring possible.

Crucially, you will act as a bridge to our Architects, ensuring that our cloud infrastructure isn't just monitored, but is built to be secure from the ground up.

We value ownership and initiative. We are looking for an engineer who can identify a security gap, plan the solution, and drive a taskforce to delivery of the solution. If you are a problem-solver who enjoys having a direct, visible impact on the security posture of a global platform, we want to talk to you.
