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. This means you will be involved in the design and evolution of both external and internal services, as well as create new mission-critical software at 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. 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.

  • Build tests for your code to maintain a high standard of quality for Sentry; as well as write documentation (with our technical writing staff) to help educate both peers and customers.
  • Review code and mentor less-experienced engineers.

You’ll love this job if you:

  • Take challenges that you don't see every day, daily.
  • Care about writing highly performant, high-quality code.
  • Want to build a product by developers for developers.
  • Take pride in developing features that don't "just work," but are delightful to use.
  • Get excited about joining a modern software development team that iterates and ships code rapidly.
  • Want to contribute to open source full-time — our product is entirely Open Source.
  • Enjoy working in an agile team of engineers who push themselves and others to do better.


  • 5+ years relevant experience.
  • Experience in solving complex problems by developing high-quality, high-performance software.
  • Experience in Python.
  • Bonus points for experience with JavaScript or Rust.
  • Excellent written and oral English communication skills and an ability to articulate technical concepts clearly and succinctly.
  • Live in the Vienna, Austria area or are willing to relocate.

  • Commuter subsidy
  • Lunch reimbursement
  • Learning & Development stipend and various other benefits
  • Flexible working schedule
