Senior Software Engineer, Developer Infrastructure

About The Role

Sentry provides tools that help developers find and fix issues in their applications. The Developer Infrastructure team owns the systems that make every engineer at Sentry more effective at shipping high quality software: developer environments, CI/CD for our open source and closed source codebases, the golden path for building new services, our SDK and library publishing tooling, and the metrics and dashboards that keep it all healthy. Our goal is straightforward: developers should spend their time thinking about the software they build for customers, not the software they use to build it. That means everything from local and cloud development environments, to the CI/CD pipeline that gets code out safely and quickly, to the tooling that catches flaky tests before they cost someone a day. As AI coding agents become part of how engineers work, we're also investing in making sure our environments, CI, and deployment systems support that shift. As a Software Engineer on Dev Infra, you'll help build and scale this infrastructure end to end.

In this role, you will

• Build and maintain the tooling that powers local and cloud-based developer environments
• Improve CI for our codebases and CD for our deployment pipeline, keeping both fast and reliable as the org and its infrastructure grow
• Define and evolve the golden path for building new services and libraries at Sentry
• Contribute to our SDK and library publishing tooling and release processes
• Build the metrics, dashboards, and flaky test detection that give the org visibility into deployment health and CI reliability
• Build tooling that gives engineers, and the AI coding agents they work with, the context they need to work effectively within Sentry's systems and conventions
• Partner directly with engineers across Sentry to understand where infrastructure and developer experience need to improve

You'll thrive in this role if you

• Get energized by building infrastructure that every engineer at Sentry depends on
• Think in systems and can reason about tradeoffs across scale, reliability, cost, and complexity
• Are comfortable owning a broad surface area, from developer environments to deployment pipelines to publishing tooling
• Want to shape foundational infrastructure rather than iterate on something already established

Qualifications

• 5+ years of experience as a software engineer or in a similar role
• Experience leading the full development lifecycle of complex projects
• Strong proficiency in Python
• Experience with Docker and container orchestration in production
• Familiarity with CI/CD systems and what makes them fast and reliable at scale
• A track record of building or significantly improving developer tooling or infrastructure
• Demonstrated ability to influence engineering teams outside your own, building buy-in for standards, tooling, or process changes without direct authority
• Strong written and verbal communication skills

Pay

The base salary range that Sentry reasonably expects to pay for this position is $190,000 to $280,000. A successful candidate's actual base salary amount will be determined by a variety of relevant factors including, without limitation, the candidate's work location, education, work and other relevant experience, skills, and job-related knowledge.
