Senior Software Engineer, Build Systems & CI (San Francisco)

DoorDash connects customers with local businesses for delivery, from restaurants to grocery, retail and its own DashMart stores. The Code Scalability team owns build systems and continuous integration across DoorDash. When a shared dependency changes or more teams contribute to a monorepo, the cost of building software can grow for everyone.

Key responsibilities

• Evolve build and CI workflows for large monorepos, keeping feedback fast and changes manageable as dependencies, code volume
• Develop Bazel rules, toolchains, and integrations that keep builds reproducible
• Improve Buildkite pipeline throughput and reliability by reducing queue times, addressing build bottlenecks
• Reduce redundant build work through dependency analysis, incremental builds, caching, and parallel execution
• Build developer tools that explain build failures and help engineers reproduce CI behavior locally, making troubleshooting faster
• Rethink what a build and CI platform can do with AI: move beyond reporting failures toward intelligent diagnosis, PR triage, automated recovery

Requirements

• 5+ years of software engineering experience building and operating production systems
• Interested in improving developer productivity and applying your engineering skills to build systems and CI
• Write maintainable production software in a language such as Go, Java, Kotlin, or Python, and bring strong debugging and software design skills
• Led technical projects across teams, made practical design tradeoffs, and carried changes through rollout and operational ownership
• Approach internal platforms as products: you listen to developers, make workflows easier to adopt
• Investigate performance and reliability problems across multiple components, use evidence to find the cause

Location and schedule

• Onsite in San Francisco, California
