Senior Software Engineer, Developer Infrastructure

Responsibilities

• 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.

Requirements

• 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.

Nice-to-Haves

• Excitement about building infrastructure that every engineer at Sentry depends on.
• Ability to think in systems and reason about tradeoffs across scale, reliability, cost, and complexity.
• Comfort owning a broad surface area, from developer environments to deployment pipelines to publishing tooling.
• Interest in shaping foundational infrastructure rather than iterating on something already established.
• Eagerness to grow even if not meeting 100% of the qualifications.
