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. 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 plat

About the team Engineering the future of customer support — at global scale 🌍 We believe exceptional customer service is more than just a feature, it’s a fundamental part of who we are. That’s why we’ve built our own internal support tooling from the ground up, tailored to help our customer, courier, and merchant support teams shine in every interaction. As we scale our operations from 30 to 60 countries, supporting millions of users and partners, our internal tools need to scale with us. The Support Engineering group is at the heart of this mission. We build high-performance admin applications and core operational tools that empower our support teams to work smarter and faster. A key part of this is our in-house chat platform, which already handles around 5 million conversations every month. On top of this foundation, we’re developing advanced features to reduce manual work, improve communication, and proactively resolve issues — often before our users even notice them. Our systems range from automated reach-outs for delayed orders to deeply integrated tools that enable our support teams to deliver assistance quickly, reliably, and with a human touch. By removing inefficiencies and automating repetitive tasks, we’re ensuring that our users and partners receive world-class support at scale. About the role We’re now looking for a Senior Backend Engineer (Golang) to join us in building scalable, low-latency systems that power these tools and shape the future of customer support. You’ll work on impactful products that directly influence how millions of people experience our platform every day. What you'll be doing Build and maintain high-throughput backend servic

About the team + role We are building an elite team, applying frontier technologies to the world’s biggest financial problems. We’re looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. Robinhood isn’t a place for complacency, it’s where ambitious people do the best work of their careers. We’re a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards. The Prime team 's mission is to build Bitstamp's prime brokerage for institutional clients — the platform that lets hedge funds, market makers, and professional trading firms onboard, fund, trade, borrow against, and settle positions at scale. We build the systems that move real institutional money: cross-venue settlement, credit against collateral, matched-book lending, and the bridge that brings tokenized securities to our order book — together with the client- and ops-facing surfaces that make them usable, from institutional onboarding and account configuration to reporting and the backoffice tooling our operations run on every day. These are correctness-critical systems where a wrong answer can't be cheaply undone — getting them right is the whole job. As a Senior Full-Stack Software Engineer, you will own the design and end-to-end delivery of features across that whole surface — from the Prime backend services down to the frontend and backoffice screens that expose them. You'll lead other engineers through problems of high ambiguity, set the technical bar for how we build for failure and not just the happy path, and follow a problem across the full institutional lifecyc
