Principal Network Security Engineer

Microsoft Azure operates one of the largest Internet Protocol (IP) networks in the world, connecting millions of servers across hundreds of data centers to customers globally. This infrastructure supports a wide range of services and requires robust security measures to ensure reliability and trust.

Their goal is to detect potential threats and ensure compliance with established security standards.

 

As a Principal Network Security Engineer and technical leader, you will help drive efforts to identify and respond to non-compliant events, including those that may indicate malicious activity. This role offers the opportunity to apply and expand your expertise in network security while developing scalable detection systems suited for a large-scale cloud environment.
