About The Position

The Opportunity As a Senior Network Observability Engineer, you will play a critical role in ensuring the reliability and effectiveness of Visa’s global network monitoring and management platforms. This role is focused on engineering, administering, and operating enterprise-grade network tools, rather than designing or operating the underlying network infrastructure. You will work within a DevOps-oriented engineering team responsible for supporting 24x7 network observability capabilities across diverse business functions. Your work will directly impact network stability, incident prevention, and the ability of engineering and operations teams to diagnose and resolve issues quickly and accurately. This is an opportunity for an engineer who enjoys deep technical ownership of tools, values operational excellence, and wants to work at global scale using a blend of commercial software and in-house engineering.
