Billions of users. Billions of dollars. Millions of products. Planet-wide reach. Sell everything: apps, games, hardware. It’s Microsoft Marketplace Services. If you are excited by working on software at the scale of one of the largest online marketplaces in the world, then this is your dream job.

The Commerce and Ecosystems team is developing some of Microsoft’s largest scale and business critical cloud services. These services have a huge global footprint of over 240 markets and process millions of transactions daily, with loads growing linearly as Microsoft moves to a ‘cloud first’, ‘mobile first’ strategy. The platform powers all of Microsoft’s key services - Windows App Store, Windows Phone, XBOX, Bing Ads, Office 365, Azure to name just a few. Whether renting a movie or buying a game on Xbox LIVE, purchasing an app on a Windows , signing up for an Office 365 subscription or paying for Azure services, you are using the Microsoft commerce platform. We are the Marketplace Services team and are responsible for the services which power Microsoft’s marketplace.

We specialize in a massive transactional infrastructure that handles the core commerce functionality of Xbox Live, Windows and Phone services. Every time a customer searches, buys, or gets a license for a product in the marketplace, they are using a Marketplace Service. If you have a gamer-tag, or if you’ve used your Xbox, Windows Store or Windows Phone to purchase a game, a song, a video, a subscription, or an app, then you’re one of our customers.
