About Sentry

Bad software is everywhere, and we’re tired of it. Sentry is on a mission to help developers write better software faster, so we can get back to enjoying technology.

With more than $217 million in funding and 85,000 organizations that believe we’re on to something, we're building performance and error monitoring tools that help companies like Disney, Microsoft, and Atlassian spend less time fixing bugs and more time building products. If you like to selfishly build things that make your digital life better, come help us build the next generation of software monitoring tools.

About the role

As a Senior Software Engineer on the Telemetry Experience team in Vienna, Austria, you will join a cross-functional group of Software Engineers that is responsible for the client-facing operation of Sentry.

The Telemetry Experience team is focused on building heuristics that help decide which events out of the billions we ingest are worth storing and which are ok to discard (Dynamic Sampling).

You will collaborate with other teams throughout the company to ensure that our customers can get to important, actionable data easier than before. The scope of work includes and is not limited to Issues, Performance, Alerts, Discover, and Dashboards. Presenting new ideas to our technical steering committee, establishing ownership of a feature set, and growing your technical skills are just a few of the activities you can expect from this role.

  • Take pride in building features that don't just work but are also delightful to use
