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.
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, a single codebase supporting a range of platforms.
You'll dive deep into the .NET ecosystem, from C# and the Microsoft.Extensions stack to the native iOS and Android layers that power crash reporting underneath. If you love using cutting-edge tech to solve complex cross-platform challenges, you've found your team.
Own the .NET (including MAUI) SDK end-to-end, guiding its development from core architecture to final product experience
Pioneer exciting new features like Profiling and Session Replay, and build out next-generation application & performance monitoring for the MAUI platform
Tackle the unique challenges of bridging managed .NET code to native platform behaviour, designing robust, high-quality APIs built to handle massive scale
Collaborate with maintainers of upstream packages — both libraries our SDK depends on and frameworks we instrument for our users
Be the go-to expert for MAUI at Sentry, helping teams and customers solve the most complex and interesting challenges across the .NET ecosystem
Love writing C# and enjoy going deep — learning how things work at the platform level, not just making them work
Get excited about building elegant, intuitive tools that other developers are genuinely excited to use
Want to contribute full-time to a major open-source project and see the immediate impact of your work
Enjoy engaging with developer communities — whether triaging issues on GitHub, collaborating with upstream maintainers, or connecting with the .NET community at conferences
Thrive alongside thoughtful, collaborative engineers who push themselves and each other to do better every day
5+ years as a Software Engineer with a strong focus on .NET and mobile platforms, ideally in SDK development or developer tooling
Strong C# and .NET MAUI experience — prior Xamarin experience is a plus
Solid grasp of the .NET ecosystem — Microsoft.Extensions, dependency injection, and how .NET integrates with native frameworks on iOS, Android, and Windows
Deep understanding of the managed-to-native interop layer, platform lifecycle differences, and the .NET runtimes underpinning MAUI (Mono, CoreCLR, Android runtime) and how they affect performance and debugging
Experience leveraging AI-powered development tools to enhance productivity and code quality
Excellent written and spoken English communication skills
Well-organized with a high level of attention to detail and accuracy
You live in the Vienna area or are willing to relocate for this incredible opportunity
Ideally, you also have experience with other cross-platform frameworks (React Native, Flutter)
Not sure if you meet 100% of the qualifications? We encourage you to apply anyway. We're interested in people who are excited about this opportunity and eager to grow.
