At Stint, our machine learning engineers sit at the centre of how intelligence reaches the real world. You’ll work shoulder-to-shoulder with data scientists, researchers, and engineers to build models, architect data systems, and power decisions across thousands of hospitality sites. One day you might be building a demand forecasting model; the next you’re shaping data pipelines, deploying models into production, or tuning performance in a high-traffic environment.
Your work will drive real-time decisions inside mobile apps, operational systems, and the tooling used by some of the UK’s biggest hospitality brands. You’ll help turn complex, messy, multi-source data into the intelligence behind our platform, and play a key role in scaling our AI systems as we expand across the UK and internationally.

Stint solves one of hospitality’s hardest problems, staying perfectly staffed when demand changes by the hour. We do this by pairing smart AI driven software with our flexible, on-demand workforce that’s ready to step in exactly when needed.
Over the last six years, we’ve focused on building our workforce of hyper-local students and other flexible workers, who are available for 2-3hr shifts exactly when our partners need them most. We have built trust within the hospitality industry, earning the confidence of major brands by proving the value of our workforce model. Now we work with some of the UK’s best-known hospitality names - including PizzaExpress, Gail’s and Pret across 4,000+ sites across 28 cities in the UK - and they all love our product.
Over the last 12 months, we’ve used this foundation to build something even more powerful: the brain behind a business’s rota planning process.
By applying AI to multi-year, proprietary and public data sources, we help businesses forecast demand, generate headcount suggestions, and build the optimal rotas automatically. When combined with our flexible workforce, our intelligent platform lets hospitality businesses run lean core teams and scale up during peak hours without overstaffing or compromising on service. What started as a smart way to fill shifts, has now become an end-to-end staffing engine that’s incredibly hard to replicate and uniquely built for the hospitality industry.
We’re looking for people to join our 50 person team who care about solving real problems with tech, are excited to grow with us, and want to build something pretty cool, very quickly. We work hard, have fun doing it, and don’t take ourselves too seriously.
We look forward to working with you!
