Senior Platform Engineer, Developer Platform

This London-based senior platform engineering position is listed as hybrid. It belongs to the Developer Platform unit, which builds the foundational tools and workspaces that let engineers release software reliably. The unit manages the developer experience around DoorDash's main monorepo, maintains the Bazel build stack, shapes environments used by both people and automated agents, and oversees IDE and agent tooling. Its declared mission is to reduce obstacles and quicken iteration throughout software delivery.

The title implies project ownership. The engineer converts customer objectives into clearly bounded sub-problems for personal and peer work, sets a demanding bar for quality, durability and scale, and weighs long-horizon consequences against immediate gains. Projects can be ambiguous, so organised project management is essential. Ownership extends to parts of the team's charter, with regular suggestions to cross-functional partners about gaps, plus a mentoring role for colleagues.

Technically, the profile emphasises strong software craftsmanship, mainly in Go or Python, with significant hands-on work in infrastructure-as-code, notably Terraform, and in managing AWS estates. Familiarity with platform domains such as container scheduling, Kafka, build infrastructure or telemetry is advantageous. Prior experience building AI-supported developer utilities, or integrating language-model capabilities into engineering tools, is also sought.

Because the tooling serves internal engineers, the quality of the work is measured by how easily and dependably those engineers can build. The company notes that its hiring process typically involves three or four rounds, and it provides an engineering interview guide to candidates.
