Senior Software Engineer, Developer Infrastructure

About Sentry Software runs the world and the pace is faster than ever. Sentry helps developers fix errors and performance issues before users notice, so teams can spend less time firefighting and more time building. Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the Role 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. This role is based in San Francisco, with three days per week in the office to work closely with Platform and Product Engineering teams. What You’ll Do 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. How You Work You enjoy building tools and infrastructure other engineers rely on. You consider reliability, performance, cost, and maintenance when making technical decisions. You take ownership from understanding a problem through implementation, rollout, and operation. You listen to engineers’ feedback and use evidence to guide improvements. You help teams adopt shared tools and standards through clear reasoning and collaboration. Qualifications 5+ years of software engineering experience or equivalent experience building developer tools and infrastructure. A track record of building or significantly improving developer tooling or infrastructure used by engineering teams. Strong proficiency in Python. Experience improving CI/CD systems, including diagnosing performance or reliability problems. Experience leading complex technical projects through design, implementation, and rollout. Experience using Docker and container orchestration in production. Experience working with cloud infrastructure such as GCP or AWS. Familiarity with Kubernetes and infrastructure as code tools. Experience working across engineering teams to build agreement on tools, standards, or workflow changes. Clear written and verbal communication, including explaining technical tradeoffs and documenting how systems work. You don’t need to meet every qualification to apply. If your experience aligns with the core work, we’d like to hear from you.
