Data Scientist

Stuart is a leading tech-enabled logistics platform that transforms on-demand delivery across sectors like food, grocery, and retail. Operating in over 130 cities across Europe, Stuart connects businesses with a network of independent couriers, providing access to fast, flexible, and efficient deliveries.
Our Mission 🚀We are an impact-driven company that aims to build the future of logistics for a more sustainable world: shared, efficient and reliable. We are committed to creating a new standard for urban deliveries that meet today’s environmental and social challenges while offering a premium delivery experience blending speed, flexibility and convenience.Stuart is a highly diverse and inclusive company of 280+ employees from different nationalities and backgrounds working across France 🇫🇷, Poland 🇵🇱, Spain 🇪🇸 and the UK. 🇬🇧
It’s the right moment and the right place for us to make an impact on millions of people, as home delivery services hit a record high. And guess what? You can help us fulfil our vision 🙌
You will join our Data Science team and play a key role in driving algorithm-driven solutions that enhance Stuart's delivery network and scale it to optimum performance. This role goes beyond business and operational challenges, offering you the opportunity to shape a variety of impactful solutions across Stuart.As a Data Scientist, you'll work on researching and implementing cutting-edge algorithms, delivering insights, and identifying opportunities and proposing solutions to improve efficiency across the organization. The role touches classical ML problems, but also operations research questions. Key areas of focus include:
- Dispatcher Solver Optimization: Refine algorithms for solving complex route optimization (e.g., Vehicle Routing Problem) at the right tradeoff of precision and speed.- Incentive Optimization: Develop strategies to guide drivers to high-demand areas while ensuring cost-effectiveness.- Ride Acceptance Prediction: Model the likelihood of drivers accepting delivery tasks to improve allocation efficiency.- Experimentation at Scale: Improve and scale Stuart's experimentation (A/B, Switchback...) capabilities to enable the different teams to make data-driven decisions.
...and more exciting challenges where you can directly impact Stuart’s mission!
This is a hands-on, high-impact role fit for someone with an analytical mindset, passionate about leveraging algorithms and models to drive real-world optimization and scalable solutions.
