Sentry's mission is to empower software development teams to build better products, faster. Our open source crash reporting platform helps almost a million developers and tens of thousands of software teams at some of the internet's most loved websites/apps (Dropbox, Uber, Airbnb, Stripe, Atlassian, and many more) discover, triage, and resolve production software issues, so they can spend less time debugging and more time building software.

As a Backend SDK Engineer on our client infrastructure team, you'll join a cross-functional group of Software Engineers that are responsible for the client facing operation of Sentry. This includes building and maintaining our Java SDK that are used to send events to the Sentry backend. This SDK is primarily used for backend services but also the base of our mobile Android SDK. You will join our team that is responsible not just for the SDK work but also the main event processing pipeline. This means you will also be involved in the design and evolution of the APIs used to ingest events into the backend and work closely together with other SDK developers that build SDKs based on the Java SDK.

As Sentry's Backend SDK Engineer, you will:

  • Work on improving and evolving our Java SDK
  • Collaboriate with the client infrastructure team to integrate the Java SDK into more platforms (mobile etc.)
  • Use a variety of programming languages, systems, and technologies to own and solve problems (on the backend we use primarily Python and Rust)
  • Collaborate with Infrastructure and Operations teams to build solutions that scale (we ingest over a billion events every day)
  • Write unit and integration tests that ensure the correctness of your work, and build out strong documentation to help educate both peers and customers
  • Assist Customer Operations to resolve live customer issues when bugs sneak into production caused by the SDKs

You'll love this job if:

  • You take pride in building features that don't just work, but are also delightful to use
  • You want to join a modern software development team that iterates and ships code rapidly
  • You want to contribute to open source full-time
  • You want to work with collaborative, thoughtful engineers who push themselves and others to do better

Examples of projects our team has worked on:


  • 4+ years as a Software Engineer and/or related role (e.g. Java, Scala, Spring, …)
  • Strong experience in developing for the Java Platform
  • Experience in programming languages used on the JVM (Java, Scala, Groovy, Clojure, …)
  • Bonus points for experience with Java on mobile
  • Live in the Vienna Austria area, or are willing to relocate


  • Contribute to an open source product used by almost a million of your fellow developers and tens of thousands of companies
  • Be part of an experienced and renowned team that cares a lot about diversity, inclusivity, and quirkiness
