About the team and position 🔥 Senior Mobile Software Engineers for the Android platform at Swile are responsible for delivering the best experience to all our end users and ensuring that our Android app performs well even on older devices, remains secure, and is stable. We are looking for a Senior Software Engineer (Android) with deep Android expertise experience to elevate platforms and lead Swile Apps to the best possible user experience. You will own user-facing features end-to-end, raise the quality bar, and push the org to operate with a consistently high bar and high performance. We also expect you to be able to deliver well-documented, tested, high-performance code in Kotlin and Java, following best development practices and ensuring that everyone on your team does the same through code reviews, always aiming to improve the quality of your team's deliveries. Your day to day activities 📈 - Own and ship Android features from problem framing → design → implementation → rollout → monitoring. - Set and enforce mobile quality targets (e.g., crash-free >99.9%, cold-start p95 down quarter over quarter, accessibility compliance, secure software). - Lead mobile architecture and standards (modularization, design system components, networking, telemetry). - Ship safely using feature flags, staged rollouts, server-driven config, kill switches, and clear rollback plans. - Instrument, monitor, and alert on critical journeys (errors, latency, jank, memory/battery, app size). - Drive cross-platform parity by defining shared foundations with iOS/Web and closing experience gaps. - Accelerate others via design/code reviews, mentoring senior engineers, CI/build-time reductions, and clear docs. - Partner tightly with Product/Design/Data; prototype, experiment, and make decisions grounded in user signals. Requirements 6+ years building large-scale Android apps; track record of shipping high-impact user features. Expert in Kotlin; strong Gradle expertise; strong Jetpack Compose/XML (ViewBinding) and Java interoperability; solid concurrency (Coroutines/Flow) and Android Profiler. Depth in networking (REST/Retrofit), offline/caching (Room), secure storage (EncryptedSharedPreferences/Keystore), privacy, and accessibility. Proven release/quality engineering: JUnit/Espresso/snapshot testing, CI/CD (Bitrise), staged rollouts, feature flags, and reliable rollback. Demonstrated org-level influence: multi-team designs, standards adoption, mentoring engineers, raising execution pace. Crisp written/spoken communication; partners effectively with Product, Design, and Backend; data-driven decisions. C1 English. Preferred requirements: Master’s degree, PhD, or equivalent in Computer Science, Computer Engineering, or related fields. Experience in cross-platform development.

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 — 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 Deliveroo, 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. ➡️ Want a deeper look at how we build?
