Software Platform Engineer, EU Traffic

Job description

Our Global Structure 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 request…
