Job description

Overview

Food waste is a $1 trillion problem – costing the world over 1% of global GDP. Winnow is focused on solving this problem. We believe that food is far too valuable to waste, and that technology can transform how we produce food. Our team shares 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 operate in over 90 countries with offices in London, Dubai, Singapore, Cluj-Napoca (Romania) and Chicago. We are a scale-up company with a strong client base rolling out our system globally. Our blue‑chip customers include Accor Hotels, IKEA, IHG, Marriott, Compass Group and many others.

Winnow’s clients on average reduce waste by over 50% by value and sustain savings. Winnow works with hotels, universities and schools, staff restaurants, event/hospitality kitchens, buffets, pubs, and high street restaurants. Where the system is permanently adopted, pre‑consumer waste value is reduced by 50% - 70% with no detrimental impact to the perceived quality or value of the offer to customers. This represents a typical improvement of food cost savings of 3% to 8%, commonly a 40%+ increase in profitability for operations.

As the global leader in addressing food waste, we are committed to continuing to push the envelope on what technology can do. Winnow Vision, our artificial intelligence based technology, is trained to automatically track all food waste thrown away. It has won awards at the World Economic Forum and has received enthusiasm from clients and the industry.

We are passionate about living our values and place them at the centre of everything we do. Equal parts head and heart. Brave honesty. People of action. Bound by food. Hungry and humble. People and planet positive. This is an opportunity to join an exciting organisation and help propel our growth at a dynamic time. You will work alongside a driven team motivated by building an exciting business and leaving the world a better place.
