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 $127 million in funding and 80,000 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 React Native 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 mobile React Native SDKs and the ecosystem surrounding it (expo, hermes, integrations). You will join our team that is responsible not just for the client SDKs 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.

In this role you will:

  • Work in the client infrastructure team to improve and evolve our React Native SDKs and mobile and desktop related features
  • Use a variety of programming languages, systems, and technologies to own and solve problems related to mobile (TypeScript in the SDK — on the backend we use primarily Python and Rust, a bit of Java/Kotlin and/or Swift/Objective-C is a plus)
  • 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, 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
  • You build a product by developers for developers
  • You join a modern software development team that iterates and ships code rapidly
  • You contribute to open source full-time — our product is entirely Open Source
  • You work with collaborative, thoughtful engineers who push themselves and others to do better

Examples of projects our team has worked on:


  • 2+ 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 (TypeScript, Kotlin, Swift, etc.)
  • Bonus points for experience with C, C++ or low level languages
  • Good written and spoken English communication skills
  • Live in the Toronto, Ontario area or are willing to relocate


  • Competitive salary and meaningful equity
  • 100% medical, dental, and vision coverage for employees, 75% company-paid for dependents
  • Monthly commuter subsidy.
  • Charitable matching program.
  • Generous parental leave policy.
  • Flexible working schedule and vacation policy, and real work/life balance.
  • Company events (Hack Weeks, All Hands, quarterly social events) and friends and family events.
  • Relocation assistance
