Senior Software Engineer (.NET), SDK 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. Sentry embraces a hybrid work model across our global hubs, with Mondays, Tuesdays, and Thursdays set as in-office anchor days to encourage meaningful collaboration. 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 THIS ROLE This is no ordinary engineering role. At Sentry, our SDK teams create the next generation of tools for developers worldwide, processing over a billion events every single day. We're looking for a talented Senior .NET Engineer to join our team and own one of the most uniquely challenging SDKs we build — sentry-dotnet https://github.com/getsentry/sentry-dotnet, a single codebase supporting a range of platforms.
