Work at Rumble

Calling All Heroes

We are building a company that will change the landscape of gaming forever. If you have a passion for great games, small teams, hard problems, and close collaboration, join us. We're hiring for:


Senior Platform Engineer
Engineering | San Mateo, CA, United States

Rumble builds high-quality free-to-play games for iOS and Android. The platform team provides a scalable foundation of shared services that enable our game developers to focus on making great games, and in doing so we touch virtually every piece of technology involved, from C# client code to back-end database servers. We manage the global operation of the services we build, and the games that use them. Our APIs handle tens of millions of requests per day from game clients and servers around the world. Join us and be an important part of a small team doing very big things.

From a technical point of view, we’re basically a Java/Linux shop on the back end, with a Unity/C# game client. All of our server applications are deployed on Amazon Web Services (AWS). We employ a wide variety of established and emerging technology as requirements dictate, not specifically for the thrills. We use Redis a lot. We release frequently and automate obsessively. We test. We do pager rotation, but we also have lives.

We generally look for competent generalists, not specific skills or experience, but value strong software engineering fundamentals as applied to real-world problems, an aptitude for learning new things, and a willingness to branch out and contribute across a broad variety of technologies and disciplines. A consummate team player with excellent communication skills will fit right in. A love of games is a big plus.

In experienced candidates, we’re looking for adaptive, innovative individual contributors who can work independently to implement and deploy scalable solutions to complex problems, and monitor the ensuing chaos. We’re going to notice experience with small startup companies with an agile/DevOps mindset, and hands-on experience with non-relational data stores and public cloud technologies.

We’re particularly interested in substantial experience with Linux, Java, Groovy/Grails, Redis, MySQL, DynamoDB, or Redshift. Our development process relies heavily on IntelliJ, git, Jenkins, and JIRA, and we deploy nearly everything on Amazon Web Services. Bonus points for experience with web front-end development (HTML, CSS, Bootstrap, jQuery), Unity/C#, Ejabberd/erlang, AWS Lambda, Python, or writing professional bash scripts.
