Deliveroo is hiring a Staff Machine Learning Engineer for its Ads Bidding team in London, on-site and full-time. The role centres on migrating advertising from cost-per-click to cost-per-order, a problem the posting says few companies have solved and has no established playbook. The person would own that migration, build bidding surfaces such as goal-based automated bidding, Target CPO, optimised CPC and Target ROAS, and own yield management tied to ROS targeting, partnering daily with the DoorDash US team. The posting asks for expertise in ad economics, marketplace bidding or auction theory, direct experience with those bidding products, 7+ years of production Python, ML fundamentals in ranking, recommendation or bidding systems, and strong cross-functional communication.
