Requirements
You have 2+ years of experience in backend, infrastructure, or platform engineering.
You have experience with gRPC, REST APIs, Protocol Buffers, and service-to-service communication patterns.
You have deep knowledge of best practices in Kotlin (or another JVM language) for building high-scale, resilient systems; familiarity with asynchronous/reactive frameworks such as Vert.x is a plus.
You have experience working on high-throughput, mission-critical production systems.
You have a strong understanding of distributed systems concepts, including consistency, fault tolerance, load balancing, and resilience patterns.
You are comfortable with API gateway and proxy concerns — authentication and authorization, request routing, and schema/contract management (e.g., OpenAPI).
Responsibilities
As a member of the Unified Gateway team, you'll build and maintain the API Gateway platform that sits at the front door of DoorDash's traffic — an HTTP-to-gRPC reverse proxy that accepts REST/JSON requests, translates them into Protocol Buffer messages, calls downstream gRPC services, and translates the responses back to clients.
The platform empowers product engineers to declaratively define, test, deploy, and operate their API endpoints without standing up and managing their own edge services.
It centrally handles authentication, authorization, request and response mapping, header propagation, encryption, and resilience, and powers experiences across DoorDash, Wolt, and Deliveroo spanning iOS, Android, and Web.
By providing this robust platform, we deliver significant improvements in:
Product engineers can iterate faster and deliver features more quickly.
The platform is designed to handle increasing demand and traffic seamlessly.
Team
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 DoorDash's three-sided marketplace of consumers, merchants, and dashers.
