Every day, tens of millions of people from around the world come to Roblox to play, learn, work, and socialize in immersive digital experiences created by the community.

Our vision is to build a platform that enables shared experiences among billions of users. This is what’s known as the metaverse: a persistent space where anyone can do just about anything they can imagine, from anywhere in the world and on any device. The breadth of opportunities, and the evolving demands of this first-of-its-kind platform, ensure that your avenues for growth are always expanding and flexible.

Join us and you’ll usher in a new category of human interaction while solving exceptional challenges that you won’t find anywhere else.

The Matchmaking team’s mission is to:

  • Provide the best player experience by choosing the best game possible
  • Handle game orchestration by ensuring optimal performance across Roblox worldwide data centers

As a Principal Software Engineer with the Matchmaking team, you’ll have the independence, opportunity, and the end-to-end responsibility to build and own mission critical services within the Roblox ecosystem.

You’ll also be a decision maker and be involved in creating the next generation of the Matchmaking system, built to scale up to 1B monthly active users. This distributed system will be highly available and support up to 1M QPS.

In order to achieve the best player experience possible, you’ll be leading experimentation, data driven projects and partner closely with data analysts. You’ll also work on our new Machine Learning prediction system to continuously improve the quality of the matchmaking decision.

Here are a few quick highlights of how we impact Roblox:

  • Matchmaking Decisions - Selecting the best game server possible for every play request is a o(n²) problem. The system currently supports several millions of concurrent players. We need YOU to raise that bar even higher!
