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. Staff Machine Learning Engineer – Ads Bidding The Team The Ads ML team builds and maintains the machine learning models powering Deliveroo's advertising product — connecting consumers with relevant ads and helping merchants, grocers, and FMCG brands grow through the platform. The UK team is ~11 MLEs across ads and promotions, and collaborates closely with the US team (meetings capped at 4pm UK to protect reasonable hours). The Problem Deliveroo is migrating ads from cost-per-click (CPC) to cost-per-order (CPO) — merchants pay when an ad drives an order, not when it's clicked. This is a genuinely open, cutting-edge problem: very few companies have solved it, and there's no established playbook to follow. The exact approach is under active discussion and you'd be central to driving it. Requirements Expertise in ad economics, marketplace bidding, or auction theory Direct working experience with optimised CPC, target CPO, goal-based automated bidding, and target ROAS Strong self-driven leadership baseline — you'll be setting direction in an ambiguous space, not executing against an established one 7+ years writing production code in Python; solid ML fundamentals in ranking, recommendation systems, or bidding/auction systems A bias for simplicity and a focus on shipping work with measurable business impact Strong cross-functional communication — you'll be working closely with Product, Commercial, and the wider DoorDash team Why Join Us?
