Technology, Data Science and AI are at the heart of Gousto. The code we write powers every aspect of our business from the recommendation engine powering our e-commerce experience right down to the genetic algorithms used to efficiently route boxes in our warehouse.

We use the latest technologies to create simple and elegant solutions to complex problems. We’re ‘all in’ on AWS using many of its services. Our platform and continuous delivery pipeline is fully automated using Cloudformation & Ansible, we release code to production multiple times a day and we’re in the process of moving our microservices architecture to containers. We build our services in Python, PHP and Node.js with a significant proportion now delivered via AWS Lambda.

Join us and let’s dream big and deliver bigger.

Unbox possibility.
