The Sentry Story

Our Co-Founders David Cramer and Chris Jennings realized that developers are at the core of virtually every organization, building and managing the software that makes modern businesses tick. With the developers' workflow in mind, they started an open-source side project that has now turned into a well-loved product used by 1M+ developers.

It is our mission to empower software development teams to build better products, faster. Our application monitoring platform helps millions of developers discover, triage, and resolve software issues, so they can spend less time debugging and more time doing what they love... building software.

About the Team

As a Sr Platform UI engineer, you'll join a cross-functional group of software engineers and designers that are responsible for the end-user operation of Sentry. Not only do product engineers build the user interfaces that software developers see and touch, they contribute to the APIs and server logic that power those interactions. If you want to build and improve product features that empower software development teams to do their best work, all while writing open source code, we'd like to talk to you.

Sentry is used by tens of thousands of developers, and as part of our small team, you'll find countless challenges to grow and succeed. If you have a technical background and want to engage publicly with the software development community, we feel this is a fantastic opportunity.
