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, with Mondays, Tuesdays, and Thursdays set as in-office anchor days to encourage meaningful collaboration.

About the role

Are you ready to shape the future of Python observability? As a seasoned Python engineer, you’ll tackle complex projects in error monitoring, tracing, and logging while exploring new approaches such as AI to improve how developers instrument and understand their applications. Join us at Sentry and build tools that empower millions of developers worldwide.

This isn’t your typical Software Engineering position. As a key member of our Web Backend SDK team, you’ll shape the future of Python instrumentation and observability, from core error monitoring and performance tracing to exploring emerging approaches in observability. You won’t just be maintaining code; you’ll be pushing the boundaries of what’s next for developer tooling.

Responsibilities

• Maintain and evolve the Python SDK: keep key integrations stable, ensure backward compatibility, and advance error monitoring, structured logging, and tracing APIs.
• Own work end-to-end: triage community issues, design, implement, and ship new features with tests, documentation, and examples.
• Explore and build next-generation observability tooling, including AI-driven approaches that simplify complex workflows.
• Represent Sentry in the open-source ecosystem: collaborate with developers worldwide and engage with popular Python framework and library maintainers.
• Work closely with the community on GitHub and with Customer Operations to resolve critical issues and deliver production impact.

Requirements

• At least 5 years of experience as a Software Engineer, with deep expertise in Python.
• Proven track record building, maintaining, or contributing to SDKs, libraries, or frameworks.
• Strong understanding of Python runtime behavior, instrumentation, and performance profiling.
• Excellent written and verbal communication skills in English.
• Based in Toronto, or open to commuting or relocation.

Bonus

• Experience contributing to or maintaining open-source libraries.
• Familiarity with AI-enabled developer tooling (LLMs, agents, etc.), especially their inner workings and practical use in observability.
• Knowledge of other programming languages such as Ruby, Java, Go, Rust, or JavaScript.
