About the team

At Skype & Teams, our vision is to re-humanize communications from the living room to the boardroom. Skype is used by family and friends across the globe. Skype for business has transformed the way millions of enterprise workers communicate and collaborate in real time. Microsoft Teams is redefining the group collaboration space with laser focus on team and individual productivity.

In recent years Skype has completely reinvented itself-replacing our P2P infrastructure with modern cloud microservices, integrating Skype with other Microsoft services (such as O365) for a fluid user experience, evolving into both consumer and business products, and supporting our users whether they run on desktop, mobile, or web apps.

Join the team that powers the entire messaging back-end for Skype, Skype for Business and Microsoft Teams.

What we do:

We develop one of the largest scale, business critical services in Microsoft. Our services run in every region of the world, serving hundreds of millions of active users and billions of requests a day. We care about milliseconds of latency and take high availability seriously. One of the major goals the team is working on is to revamp and re-architect our services for planet scale while enabling rich and highly sophisticated experiences. This effort includes redesigning the storage, scaling the compute, re-architecting the network protocols, optimizing high volume data feeds that power AI, and such. Another important part of our everyday work is to cooperate, develop or extend engineering services to other MS product teams mainly improving continuous integration (CI) test execution system and frameworks.

What to expect:

You will have a chance to work with cutting edge technology powered by Azure - schemaless DB, distributed caching, Service Fabric, etc. Every service must be highly scalable, highly-available and extremely performant in a geo-redundant multi-tenant system honoring obligations for data sovereignty, privacy, security and compliance. In this role, you will be responsible for all aspects of the services (design, development, quality, production deployment, service availability & reliability). You will have an opportunity to work in a fast-paced agile setup beside a set of awesome engineers and have fun along the way. If you relish challenges on a day to day basis and love to solve problems at massive scale as well as learn from great but humble minds, this team is for you. Given the impact of the service, this team is growing fast, and every member will have enough and more problems to solve providing excellent growth opportunities.
