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.

We're looking for a Machine Learning Engineer to join our London office as part of a Global DoorDash Engineering team (working hybrid, 3 days in the office). Our New Verticals team exists to grow monthly active usage outside of restaurant ordering — groceries, retail, and everything in between. That means turning someone who only orders restaurant food into someone who also uses the app for a grocery run, and turning dormant users into active ones. You'll work on the surfaces that make that happen: the homepage, vertical landing pages, and the notifications that bring people back. This role sits closer to the personalisation and ranking side of that mission, working alongside colleagues across DoorDash, Deliveroo and Wolt. What You'll Be Doing Build and improve ranking models for vertical landing pages (grocery, retail), deciding what a user sees first when they land on a store page Design models that blend new-vertical content into a homepage built around restaurant ordering, without disrupting the core experience Build personalisation models that translate a user's existing behaviour into relevant recommendations for verticals they haven't tried yet Contribute to notification targeting — who gets notified, with what message, and when, to drive adoption of new verticals What You'll Need to Thrive Minimum 3+ years of experience as an ML Engineer or Data S

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. Senior Product Manager, Core People Technology Location: London | Work model: Hybrid | Reports to: Senior Manager, People Product About the team People Technology builds and runs the systems behind every hire, transfer, leave, pay change and offboard for our workforce across DoorDash, Deliveroo and Wolt. Our mission is to make the operational backbone of People Operations invisible when it works — reliable, compliant, and scalable across dozens of markets — so our people teams can focus on people, not process. This role sits on the People Product team, working alongside Business Systems Analysts, engineers and delivery leadership to bring product thinking to one of our highest-volume, highest-consequence surfaces. About the role Core is the Workday and HR platform surface that nearly every People Operations process runs through — pay, leave, employment status, right to work, and multi-country compliance for a global workforce. Demand structurally exceeds capacity, and requests arrive from every direction without a shared shape. You'll be the first dedicated product manager for this space, responsible for turning that inbound chaos into a defensible, well-communicated plan — and, over time, for building the intake, frameworks and partnerships that let the space run on systems rather than on you. This is a hands-on individual contributor role: you'll be shaping tickets and sizing work alongside analysts and engineers, not managing from above. What you'll be doing Own the prioritised order of work for Core — building a clear, ranked plan, explaining the reasoning behind it, and being explicit about what's being deferred and why Turn vague or incomplete partner requests into doc

Working at the intersection of data, design and engineering, we set direction, prioritise what matters most, and deliver outcomes that move the business forward. We’re looking for a Product Manager to join our London team. This is a hybrid role. In this role, you’ll help us define and build purpose-built, highly differentiated shopping experiences across our growing portfolio of Retail categories. What You’ll Be Doing You’ll be joining the Retail Categories team. Retail only wins category by category; a single, generic shopping experience cannot do justice to the unique ways people buy apparel, auto parts, or home improvement goods. This role owns the end-to-end category shopping experience for a defined portfolio, transforming broad customer promises into shipped surfaces and distinct emotional hooks that drive habitual buying behavior. Here’s what your day-to-day might look like: Define Category Strategy: Formulate the category experience strategy and decide which categories and bets to invest in first, sequencing for maximum growth and impact. Execute Signature Product Bets: Translate each category's promise into concrete, testable product bets—such as personal-shopper features using doorstep returns for Apparel or fitment-accurate part lookup for Auto Parts—and ship them end to end. Optimise Category Surfaces: Own the category merchandising and storefront surfaces that differentiate one vertical from anoth

About Sentry Software runs the world and the pace is faster than ever. Sentry helps developers fix errors and performance issues before users notice, so teams can spend less time firefighting and more time building. Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role Agents are becoming the default way developers ship LLM-powered software, and they are miserable to debug. A single run fans out across model calls, tool calls, retries, handoffs between agents, and multi-turn conversations that only make sense as a whole. When one goes wrong, the developer usually has a log line and a shrug. Sentry's Agent Tracing turns that into something you can actually inspect: agent runs, tool calls, model interactions, token usage and cost, conversations you can replay message by message. As a Senior Software Engineer on the Telemetry Experience team, you'll own that product surface - Python/Django and Postgres on the backend, React and TypeScript on the frontend, sitting on top of Sentry's trace storage. You'll work with the SDK engineers who instrument the agent frameworks upstream and own everything customers touch downstream: the dashboards, the conversation views, the APIs, and the workflows that turn a confusing agent run into an obvious fix. In this role you will Own projects end to end. Take a problem from a rough customer complaint through scoping, design, implementation across the stack, rollout, and measurement. You'll write the design doc, cut the work into shippable pieces, and stay with it until the numbers move Build the views developers debug agents in. Multi-agent workflows, conversation replay, cost and token breakdowns, the moment where a run failed and why. Making a deeply nested, wildly variable trace legible is a genuinely hard interface problem Make the data underneath fast and queryable. Filtering and sorting millions of conversations, getting cost calculation ri
