QA Automation Engineer - Mid/Senior Level

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 IoT tools in the kitchen. We have worked with thousands of sites and are operating in over 90 countries around the world, supported by our offices in London, Dubai, Singapore, Cluj-Napoca (Romania) and Chicago. We are a scale-up stage 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.

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 their 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 to solve this problem. Winnow Vision, our new 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 tremendous enthusiasm from our clients and the industry. You can read more about it on our website and in this article in Forbes.

Other recent accolades saw Winnow listed in the 2025 Sunday Times Best Places to Work - a recognition based on feedback from our UK team. While this award is based in the UK, it reflects something global: a culture built on purpose, collaboration, and the belief that businesses can - and should - tackle real-world problems while being great places to work. Previous awards saw Winnow in the top 10 of the FoodTech 500 awards - the world's first definitive list of the global entrepreneurial talent at the intersection between food, technology, and sustainability, as well as winning Impact 50's most impactful companies to work for.

We are passionate about living our values and placing them at the centre of everything we do. We are excited about like-minded talent who share these values, joining us in our mission:

Equal parts head and heart. We’re both passionate and measured. We carefully balance the need for quick solutions and pragmatism with the ability to step back, take in the bigger picture, and build for the long term.

Bravely honest. With each other, that means we’re a transparent organisation where healthy, respectful debate is encouraged. With our customers, we challenge them if we don’t think they’re achieving their goals, whether they be environmental or financial.

People of action. Done is better than perfect, and we learn by boldly doing, then rapidly improving. We’re breaking new ground, so we know things might go wrong. But we judge ourselves and each other on our reaction and our resilience.

Bound by food. We’re a diverse bunch, but our belief in the value of food is the common thread in everything we do. With each other, we celebrate through our love and respect for food. With our customers, it means we work hard to develop creative tools to make it easy for chefs to value food.

Hungry and humble. Our product is revolutionary, our people are impressive, and we’re hungry for change. But we’re just the catalyst for a bigger movement. We stay humble regardless of our success, and make chefs the heroes in this journey.

People and planet positive. We’re caretakers of the planet, helping to preserve and support it for now and the future. Our work already minimises the impact that the hospitality industry has on the planet, and we’re also committed to actively reducing our own footprint while doing so. We’re leaving the planet and its people better off than we found them.

This is an opportunity to join an exciting organisation and help us propel our growth at what are truly the most exciting and dynamic points in time in our business. You will work alongside a driven team who are motivated by building an exciting business and leaving the world a better place than we found it.
