Senior Software Engineer (Developer Infrastructure)

• The Developer Infrastructure team builds the systems Sentry engineers use to develop, test, and ship software. We own local and cloud development environments, CI/CD across our open-source and private codebases, tooling for creating new services, and SDK and library publishing
• Our goal is to help engineers spend more time building for customers and less time troubleshooting their development tools. You’ll work on problems such as shortening CI feedback cycles, improving deployment reliability, detecting flaky tests, and making development environments easier to use and maintain
• As AI coding agents become part of engineering workflows, you’ll also help our environments, CI, and deployment systems support them with the context and access they need
• You’ll own projects from design through rollout and ongoing operation, working directly with engineers across Sentry to understand their needs and measure whether your changes improve their work
• Build and maintain tooling for local and cloud development environments
• Improve the speed and reliability of CI and deployment pipelines as our codebases and infrastructure grow
• Develop supported, reusable workflows for creating services and libraries
• Improve SDK and library publishing tools and release processes
• Build metrics, dashboards, and flaky test detection to help teams identify and resolve development and deployment problems
• Give engineers and AI coding agents the context they need to work within Sentry’s systems and conventions
• Partner with engineering teams to prioritize improvements, support adoption, and evaluate results
• You listen to engineers’ feedback and use evidence to guide improvements
• You help teams adopt shared tools and standards through clear reasoning and collaboration
