Winnow

Data Scientist Lead

Job description

ABOUT US

Food waste is a $1 trillion problem – costing the world over 1% of global GDP. We’re dead set on solving the problem and looking for people to help us achieve our mission. We, at Winnow, believe that food is far too valuable to waste, and that technology can transform the way we produce food. Our team is made of people who all share a passion for food and technology.

Winnow was founded in London in 2013 to help the hospitality industry prevent food waste through internet of things tools in the kitchen. We have worked with hundreds of sites and are operating in over 35 countries around the world supported by our offices in London, Chicago, Dubai, Shanghai and Singapore. We are a rapidly growing company with a strong base of clients who are rolling out our system globally. We have blue-chip customers including Accor Hotels, IKEA, IHG, Marriott, Compass Group and many others.

We are passionate about living our values and place them at the centre of everything we do.


THE ROLE

About the team

The Data team plays a critical role in the continuous improvement of our flagship product - Winnow Vision. We've collected millions of images of food items already, and keep collecting thousands every day from the kitchens we operate in. Those images need to be processed, curated and structured to optimise the quality and accuracy of our AI models. Managing this big data pipeline is no easy task: we operate across the world, in a wide variety of industries and our model needs to recognize food ranging from the Malay Nasi Goreng to the American fried chicken, and everything else in between.

We have come a long way - from long data collection time and training small AI models for very specific clients, we have now managed to generalise our approach and can now deploy AI models to almost any kitchen in the world in a matter of a couple of weeks. However, there are still many challenges ahead - today we present a top selection of items to our clients and they confirm the right one - our ambition is to become completely touch less. How can we make our models more confident and more accurate, that is the question!

The Data & Analytics team consists of 9 people (6 in Cluj and 3 in London) and is expected to continue to grow in the coming months. Roles range from data operation executives to data scientists.
