At Deliveroo we have a world class data science organisation, with a mission to enable the highest quality human and machine decision making. We work throughout the company - in product, business and platform teams. We are uniquely placed to connect and calibrate quantitative decision making throughout Deliveroo, and have strong relationships with our business partners.
Our team members use technical skills from the whole spectrum of data science: building analytical tools; informing decision making at all levels of the business via bespoke and automated analysis; running experiments; performing causal analysis; informing planning and prioritisation with robust impact estimates; building production machine learning and optimisation models; and upskilling the entire company in data literacy and data driven decision making.
Data scientists at Deliveroo report into our data science management team, and we have a strong, active data science community, with guest lecturers; a robust technical review process; a career progression framework; and plenty of opportunities to learn new things. We have career pathways for both managers and individual contributors.
Our data scientists come from many disciplines including mathematics, statistics, economics/econometrics, physics, psychology, finance, computer science, operations research, cognitive neuroscience and engineering. Some are formally trained in data science, some are not. We have team members from all over the world, and have a dedicated data science diversity committee.
About the role
In this role, you will be designing and building the algorithmic and machine-learning systems that power Deliveroo. You will be working in a cross-functional team alongside engineers, data scientists specialized in algorithms and inference, and product managers to develop systems that make automated decisions at massive scale. Your team has a high degree of autonomy and works at some of the most interesting problems at the intersection of riders, consumers, and restaurants.
We evaluate the performance of all our decision making machines via robust experimentation, usually through our world class experimentation platform.
We are looking for a senior data scientist from an algorithms background, to build intelligent decision making machines. These machines may:
  • Optimise our delivery network by making rider assignment decisions; predicting how long a leg of the delivery journey will take; or mitigating real time delays
  • Work out how many riders we need in a particular place at a particular time
  • Optimise consumer and rider fees
  • Optimise the consumer experience by showing the most relevant restaurants and dishes
  • Detect fraud and abuse from consumers, riders, and restaurants
  • Assist restaurants in optimising their presence on Deliveroo, for example by recommending that they improve their menus or photography, or add a popular dish
  • Create an ML platform to improve our ML and optimisation capabilities
  • You are someone who knows the fundamentals of machine learning and/or operations research and knows when they should be applied.
  • You are a keen problem solver, able to think deeply about a business problem and devise a well-thought-out and pragmatic algorithmic solution. And you get satisfaction from seeing your algorithms shipped and driving measurable impact to the business.
  • Significant experience building intelligent decision making machines in industry.
  • Significant experience with end to end productionisation of these models
  • Ability to take a fuzzy business objective and turn it into a problem that can be solved via machine learning and optimisation, in particular experience in selecting business-appropriate objective functions
  • Great communication skills - in person, in writing, in code; to technical and non-technical audiences
  • Experience creating new decision making machines from scratch, and designing and building MVPs that quickly get results
  • Experience mentoring junior colleagues
  • A pragmatic, flexible approach, where you most care about achieving impact
Data Science at Deliveroo
We are a small team, with very large impact, seeking to answer some of the most interesting questions out there. We move fast, we’re always looking for new ideas and we’re very transparent about the decisions we make and why we make them. There are so many questions we need to answer and plenty more we haven’t even encountered. How do data and technology help restaurants to grow as consumer habits change? How can we predict what someone wants to order for dinner long before the idea has even crossed their mind? At Deliveroo these are just some of the tough problems we are solving - and there is no challenge that cannot be yours. No solution is owned by a particular team, which means the scope for growth and personal impact is enormous.
Benefits and Diversity
At Deliveroo we know that people are the heart of the business and we prioritise their welfare. We offer a wide range of competitive benefits in areas including health, family, finance, community, convenience, growth, time away and relocation. We believe a great workplace is one that represents the world we live in and how beautifully diverse it can be. That means we have no judgement when it comes to any one of the things that make you who you are - your gender, race, sexuality, religion or a secret aversion to coriander. All you need is a passion for (most) food and a desire to be part of one of the fastest growing startups in an incredibly exciting space.
