The Local Dev Ex team within the Foundations group empowers engineers to develop, test, and ship high-quality services quickly and confidently. We own and evolve the local developer experience across the Door Dash group of companies via a paved-path Dev Containers-based development platform for engineers & agentic workflows, with related IDE tooling. The team’s mission is to enable engineers across the engineering pillars of Quality, Velocity and Efficiency by building framework-level tooling and developer flows that scale across the company.

As a Staff Platform Engineer, you will be recognised as an expert in at least one relevant technical area and be responsible for solutions that deliver group-level (multiple team) outcomes. You will lead technical direction for at least 1 team, remove deep technical blockers across teams, and mentor other engineers. You will report to senior managers and as leads for the group, work together to deliver wide impact.

Technical Leadership

• You will define the technical solutions for important business problems and understand the context in which large company decisions are made, including;
• Define and own the technical architecture for local and remote dev flows: including devcontainers, IDE remote backends, and build seamless integration points into our engineering ecosystem
• Design and continuously improve the paved-path developer journeys: time-to-first-change, onboarding flows (MSC distribution, Tailscale setup), IDE remote flows, and UX for day-to-day developer tasks. Instrument and iterate based on developer metrics and feedback.
• Own the integration strategy for remote execution (Build Buddy or equivalent), accelerate development on the company monorepo (Pedregal). Define caching/invalidation approaches and CI/remote-exec interactions to keep developer loops fast and predictable.
• Your work will also include forecasting and managing project timelines and risks, and setting a sustainable and incremental team pace.

• Align non-adjacent teams and disciplines (including Product, Security, Core Infrastructure and Product Engineering) to resolve unstructured and ambiguous challenges. This extends to coaching other folks across all levels and supporting up-and-coming leaders in the team.
• Mentor senior and mid-level engineers, run technical design reviews, and raise the engineering bar through code reviews and architectural guidance.
• Lead engineering interviews and help set the bar for hiring. Help onboard senior engineers and contribute to interview loops and hiring decisions.

• You are recognised as deeply experienced in developer platforms or related infra: devcontainers, remote development, remote IDE backends, or developer workstation tooling. You’re sought out for advice and design reviews by multiple teams.
• Demonstrated shipping production systems and delivering cross-team initiatives that impact group goals. Comfortable owning end-to-end technical delivery from design to production.
• Hands-on experience with CLI/tooling platforms and developer UX; practical experience with languages and tooling used for developer tooling (e.g., Go, Python, Type Script) and infra as code (Terraform).
• Practical experience with Jet Brains remote backend flows or Code spaces/Code server-style products.
• Experience with Build Buddy or remote build/execution systems, large cache architectures, or Firecracker/lightweight VM snapshotting.
• Experience integrating LLM/AI tooling into developer flows (on-device or code-local assistants such as Claude Code), including considerations for privacy, auditability and safe defaults.
• Excellent communicator who can influence Product and senior stakeholders and align multiple non-adjacent teams.
• Experience of working closely and building relationships with customer engineering groups
