About the role
Join us in our mission to transform the way people shop and eat, where impact, innovation and growth drive everything we do. Our Engineering teams tackle complex technical challenges across a global, three-sided marketplace, building and scaling systems that serve millions of customers, riders and partners every day. From real-time logistics to resilient infrastructure and marketplace optimisation, we design, build and operate technology that powers Deliveroo’s growth at scale. We’re looking for a Senior Android Engineer to join our SDUI team. In this role, you’ll help us build and scale our server-driven UI ( SDUI ) platform, enabling teams to build a UI once and have it deploy seamlessly to iOS, Android, and Web without redeploying a new app — performantly and consistently. This role is based in our London office with a hybrid setup, typically three days in the office. What You’ll Be Doing You’ll be joining the SDUI team. We own the Android rendering layer of our server-driven UI platform, and the backend services that drive it, ensuring every consumer surface built on it is fast, correct, and visually indistinguishable from native. Here’s what your day-to-day might look like: Drive technical execution by designing, building, and evolving the Android SDUI renderer — and the backend services (Kotlin, Golang, Protobuf) that feed it — to handle complex, real-time UI updates at scale. Lead architectural improvements and code reviews, ensuring the maintainability, visibility, and operational health of the renderer as more teams build on top of it. Partner with cross-functional disciplines (iOS and Web renderer engineers, product and design teams) to plan rollouts, align on platform decisions, and influence the roadmap. Own large-scale initiatives from design to delivery — including the push to bring SDUI motion and interaction quality to native-equivalent, and the ongoing migration off legacy rendering systems. Support the growth of others by mentoring colleagues and taking an active role in our engineering hiring process. What You’ll Need to Thrive Our ideal candidate will bring strong expertise in some of these areas and curiosity to grow in others: 5+ years building Android applications at scale , with a deep understanding of Kotlin and Jetpack Compose. Backend development experience , specifically with Golang, Kotlin, and Protobuf, and the comfort to move between client and server code as the work demands. Experience building or maintaining a server-driven / declarative UI system , with a keen interest in pushing what's possible with declarative rendering —
