Senior Infrastructure Engineer Jobs in Madison, WI

Every day, engineering teams across Sony Interactive Entertainment rely on the platforms we build to deliver secure, resilient, and scalable services. IT Cloud Foundations engineers the cloud capabilities that power enterprise business systems, developer platforms, and data services across the company.

Our customers are both engineers and the businesses they support. Every improvement we make to automation, reliability, security, and cloud infrastructure directly accelerates engineering teams while improving the reliability of critical business services.

The solutions we build become reusable capabilities that scale across the enterprise-not just for a single application or project.

Our mission isn't simply to manage cloud infrastructure-it's to engineer the secure, scalable cloud platform that enables Sony Interactive Entertainment to operate, innovate, and grow.

As a Senior Cloud Infrastructure & Platform Engineer, you'll lead some of our most important cloud initiatives from design through production. 

You'll combine deep technical expertise with sound engineering judgment to design and deliver secure, resilient, and scalable cloud capabilities supporting business-critical services across Sony Interactive Entertainment. 

This is a hands-on engineering role where you'll partner with Networking, Security, Identity, Database, Platform, Data, and Application Engineering teams to solve complex infrastructure challenges, mentor fellow engineers, and continuously improve how cloud services are delivered.

Whether you're designing reusable Terraform modules, expanding Kubernetes platforms, improving observability, or automating operational processes, your work will help shape the shared engineering platform that teams rely on every day.
