About Winnow

Winnow is developing cutting-edge technology to tackle the $1 trillion global food waste problem by transforming the way we produce food.

Established in 2013, we are currently operating in over 70 countries, and we are just at the start of our journey.

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. For example, 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 tremendous enthusiasm from our clients and the industry. You can read more about it on our website.

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.

At Winnow, technology is more than code; it is a force for environmental change. If you want to apply your coding skills to solve real-world problems and contribute to a more sustainable future, we would love to hear from you.

Our intern programme

As a Software Test Engineer Intern, you will help improve the quality and reliability of Winnow’s products by developing automated testing tools and infrastructure. You will work closely with our engineering and quality teams to design and implement systems that help validate our computer vision technology and supporting software.

In this role, you’ll use your coding skills to build tools, prototypes, and automated tests that help us verify that our systems behave correctly in real-world scenarios. One example area is developing automation that allows us to simulate food waste events for our Winnow Vision computer vision system.

This internship is a great opportunity to gain hands-on experience with:

• Automated testing and quality engineering
• Building developer tools and testing infrastructure
• Working with APIs and backend services
• Supporting computer vision system testing workflows
• Collaborating with engineers in an Agile environment

We’re looking for someone who enjoys solving practical problems with code, thinking about how systems can be tested and automated, and building simple, reliable solutions.

Our Tech Stack

During your internship, you’ll gain exposure to parts of our current stack, which includes:

• Java, VueJS, React, Go, Python
• Spring Boot, Apache Camel
• SQL (MySQL, PostgreSQL), Amazon Redshift.
• REST APIs
• Kafka, MQTT
• Docker for both our cloud and edge-device applications
• Microservice-style, event-driven cloud architecture with AWS-based services (Lambdas, ECS, EKS, etc.)
• IoT ‘smart’ edge devices (Android tablets / Nvidia TX2)
• Linux-based embedded OS on our Edge devices
• Continuous Integration and Delivery using Jenkins, SonarQube
• Terraform, NewRelic for infrastructure management
• …and other supporting technologies

About you

• You’ll be pursuing a degree in Computer Science, Software Engineering, or a related field
• You’ll have a strong foundational knowledge of programming principles and data structures
• You’ll be familiar with at least one modern programming language (e.g., Java, Go, Python, JavaScript)
• With a genuine interest in AI, IoT, and modern cloud-based architectures, you’ll be curious about learning how large-scale, real-world systems are built and deployed
• You’ll be excited to work in a fast-paced, evolving environment
• With a proactive mindset you’ll be looking for a role where you can use your initiative to problem solve and take ownership for your work
• You’ll enjoy collaborating with colleagues and will be eager to learn and grow

Join us this Summer and you’ll look forward to:

• A competitively paid, 10-week summer internship (starting 13th July 2026)
• 2 Wellness hours per month, plus a 274 RON gross monthly wellness allowance
• Meal tickets - 40 RON per working day
• A permanent offer to join Winnow if you are successful on your internship (which can start on a part-time basis if you are still completing your studies)
• A highly supportive environment with your own buddy and manager who will provide regular, constructive feedback throughout the programme
• The opportunity to present your work to senior stakeholders and the company Founders
• Joining a group of equally talented interns with regular social events planned
