What is Yammer?

Microsoft Yammer is THE social network for the workplace. Millions of employees, including 85% of Fortune 500 companies use Yammer every day, to build community and culture, share knowledge, and connect with their leaders and each other.

Why Yammer?

Yammer was one of the first startup unicorns this past decade, which was acquired by Microsoft in 2012. A lot of what makes working at Yammer special is the unique blend of being a “startup” within a market-leading tech company.

You can be part of a renaissance at Microsoft, without leaving your love of Linux, java, ruby, rails, and open source behind.

Why the Core Application Platform Team?

Our team builds, maintains, and operates the backend services that deliver Yammer to our end users. We work in small, cross-functional teams to design, deliver and operate highly scalable microservices, written primarily in java and ruby on rails. The CAP team’s immediate customers are the internal engineering teams who build the client experiences for millions of Yammer users.
