Job description

Deliveroo is now part of DoorDash, bringing together teams with even greater reach, scale, and ambition. Depending on your role, you may collaborate with teammates, systems, and leaders across DoorDash and Wolt. Together, we’re unlocking new possibilities as one global team.

About the Company

Help us build the world's most reliable, on-demand logistics engine for last-mile delivery! We're bringing on experienced engineers to help us create and maintain a 24x7, no downtime, global infrastructure system that powers the company’s three-sided marketplace of consumers, merchants, and riders.

About the Role

We are looking for experienced engineers to join the EU Traffic team, based at Deliveroo, part of DoorDash, and help build the next generation of DoorDash’s Traffic platform. We are building a single, shared platform designed to serve DoorDash, Deliveroo, and Wolt, so your work will shape reliability and security for all three marketplaces. Our team owns the infrastructure that carries every request into and through that platform: the edge, where we manage Cloudflare (CDN, DNS, rate limiting, bot mitigation) and the ingress systems for external traffic, and service-to-service (S2S) communication, where we run the service mesh and the authentication that secures calls between thousands of services across multiple regions.

You will work on core components of our traffic stack, including our Cloudflare edge configuration (managed as code), and service-to-service authentication and authorization (workload identity, token issuance and validation at the mesh layer). This role sits at the intersection of distributed systems, networking, and security. It includes designing, building, and maintaining systems that must operate reliably and efficiently across some of the most critical and latency-sensitive workloads at DoorDash, from the first byte at the edge to the last hop between services.

You will report to the Engineering Manager of the EU-Traffic Team within the Infrastructure organization. This role is hybrid working from London.

You’re excited about this opportunity because you will…

• Design and build large-scale distributed systems that are high RPS and latency sensitive
• Troubleshoot, debug, and fix issues that affect production and maintain our SLAs
• Work collaboratively with other platform and product engineers to deliver on feature requests and solve their problems
• Find ways to improve the team’s productivity and operational capabilities through the use of automation, AI tools, and other avenues
• Participate in a shared on-call rotation and help lead production investigations and incidents, with support from teammates
• Mentor and learn from teammates through design reviews, pairing, and incident reviews

We’re excited about you because…

• You have 5+ years of experience as a software engineer in infrastructure, networking, or platform engineering/SRE
• Experience operating edge technologies at scale, such as CDN, WAF, proxy layers, and DNS
• Solid understanding of networking fundamentals like TCP/IP, HTTP, HTTP/2, gRPC, Load Balancing
• Background working on and debugging high-QPS or latency-sensitive systems
• You’re curious, collaborative, and comfortable making progress in ambiguity
• You work AI-first: you delegate to and orchestrate coding agents (e.g., Claude Code, Codex, Cursor) across design, implementation, testing, incident response, and releases

If you don’t meet every requirement but are excited about this work, we’d still love to hear from you.

• Experience with programming languages like Go, C++, Python or Rust
• Experience with AWS, especially with networking primitives like LBs, Privatelink, etc. and Kubernetes or other container management tool
• Experience with service mesh technologies such as Envoy, Istio or Linkerd
• Familiarity with xDS or control plane architectures
• Experience building RPC frameworks or client-side networking libraries
• Experience with Infrastructure as Code tooling like Terraform
• Experience with Gitops delivery tooling such as ArgoCD, Helm, Atlantis.
• Track record of sharing prompts, tooling, and practices that make a whole team faster with AI
