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 100,000+ 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 Mobile SDK Engineer on our client infrastructure team (SDK), you'll join a cross-functional group of engineers who are responsible for the client-facing operation of Sentry.

This includes building and maintaining our mobile SDKs (iOS, Android, React Native and Flutter) that are used to send events to the Sentry backend. You will primarily own our React Native SDK, as well as the Mobile platform end-to-end. This means you will also be involved in the design and evolution of the APIs and product experiences powering our Mobile offerings.

In this role you will

  • Work with product engineering and client infrastructure teams to improve and evolve Sentry's Mobile products - like building the future of performance monitoring, and working on new technologies like Session Replay
  • Use a variety of programming languages, systems, and technologies to own and solve problems related to mobile SDKs: Swift, Objective-C, TypeScript, Kotlin, Java and Dart
  • Collaborate with the other SDK teams on API and protocol design that scale (we ingest over a billion events every day)
  • Write unit and integration tests that ensure the correctness of your work, as well as 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
  • Are intrigued by the chance to build a product by developers, for developers
  • Enjoy contributing to open source full-time — our product is entirely Open Source
  • Want to join a modern software development team that iterates and ships code rapidly
  • Love to work with collaborative, thoughtful engineers who push themselves and others to do better


  • 5+ years as a Software Engineer and/or related role (e.g. mobile app developer, SDK engineer)
  • Experience in developing for mobile platforms (iOS and/or Android)
  • Experience in programming languages used on mobile platforms (Swift, Objective-C, TypeScript, Kotlin, Java, Dart)
  • Good written and spoken English communication skills
  • Experience with React Native is a big plus, bonus points for experience with Flutter, C/C++, or maintaining open source libraries
  • Live in the Vienna area or are willing to relocate
  • Please note the following:
    • Visa sponsorship is not available for this position
    • This is a full-time position
