Job description

About the Team

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. We tackle that challenge with Bazel, Buildkite, and infrastructure that keeps everyday development efficient. Our work gives teams a dependable path from a code change to a completed build, with fewer delays and less infrastructure troubleshooting.

About the Role

As a Senior Software Engineer on Code Scalability, you will solve the engineering problems behind building software at DoorDash’s scale. A change deep in a monorepo can trigger work across many projects; your job is to make that work efficient, predictable, and easy to investigate when something goes wrong. Projects span Bazel configuration and tooling, Buildkite orchestration, build execution and caching, and the services that support them. You will identify where improvements matter most, make the technical decisions, and work with teams across DoorDash to put those changes into practice. The impact of this role extends to every team that depends on our platform. Shorter queues give engineers more time to iterate, dependable pipelines prevent interruptions, and useful diagnostics help them get back to their work. You will measure progress through those outcomes, alongside the cost and maintainability of the infrastructure you own. You’re excited about this opportunity because you will…

We’re excited about you because…

You have 5+ years of software engineering experience, including building developer infrastructure, build systems, or CI platforms. You write maintainable production software in a language such as Go, Java, Kotlin, or Python, and bring strong debugging and software design skills. You have experience with build or CI systems at scale and can reason about dependencies, incremental builds, caching, and distributed execution. Experience with Bazel, Buildkite, or large monorepos is especially relevant; comparable tools and environments count too. You have led technical projects across teams, made practical design tradeoffs, and carried changes through rollout and operational ownership. You approach internal platforms as products: you listen to developers, make workflows easier to adopt, and judge success by the problems you solve for them. You can investigate performance and reliability problems across multiple components, use evidence to find the cause, and choose solutions that stay understandable as the system grows. You improve how a team works through mentorship, clear communication, and automation that removes repetitive work. We expect this position to be filled by 11-16-2026
