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 an Engineer on our Web Frontend SDK team, you'll join a cross-functional division of Software Engineers that are responsible for the client-infrastructure operations of Sentry.

In this role you will

  • Work in the client infrastructure team to improve and evolve our JavaScript SDKs
  • Collaborate with Infrastructure and SRE 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

  • Want to join a modern software development team that iterates and ships code rapidly
  • Get excited about contributing to open source full-time — our product is entirely Open Source
