Senior Software Engineer, Android in London

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 the company’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.

• 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 — bonus points if that included Litho or another DSL-based renderer.
• A product mindset, and the instinct to apply it to how you design platform services for the teams that build on top of them.
• Demonstrated ownership of technical delivery within cross-functional teams, guiding implementation choices and technical design for a platform other teams build on.
• Strong communication skills, working across time zones with iOS, Web, and Backend counterparts, plus PMs and multiple product teams.
• A pride in software craft, with a commitment to writing readable, well-designed, and thoroughly tested mobile code.
• Bonus points for exposure to Figma-to-code tooling, design-token/theming systems, or accessibility work in mobile rendering.

Why Join Us?

At the company, you’ll do work that matters — solving real problems for a platform that every consumer-facing team builds on. We’re renderer engineers, systems thinkers, and platform builders, brought together by a shared drive to make shipping UI changes fast and safe. Working here you can expect to:

• Solve meaningful problems at real scale — Work on a rendering platform that every consumer surface depends on, used by millions of customers every day.
• See your impact, fast — Ship, test and improve the renderer quickly in a low-hierarchy, high-ownership environment.
• Grow through challenge and ownership — Take on big, ambiguous platform problems and accelerate your career with strong support.
• A culture built for builders — High standards, collaboration, flexible working and continuous learning.
• Share in the success you help create — Competitive salary and equity options, so you’re rewarded for the impact you make.

We aim to create a fair process that lets your skills shine—our interview typically includes 3-4 stages. Explore our Engineering Interview Guide here to help you feel confident at each stage.

Diversity, Equity and Inclusion: At the company, we know that a great workplace reflects the world around us and that true diversity and inclusion make us stronger, more creative, and better at what we do. We’re committed to fostering an environment where everyone can do their best work and feel they belong.
