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
