Working in a fast-paced Agile environment, you will have significant ownership and technical influence, and see your efforts quickly deliver benefits to the business.

A Culture of Continuous Improvement

We know that however good we are now, we can always be better. We try and apply this philosophy to our products, the code we write, and our own skills. 

For our products, we try to identify what we work on next using data: what is going to deliver the most value? What problems are most important to our users?

For our code, we are always looking for ways to make it more readable, reliable and efficient. All the code we write is peer-reviewed to help us spot bugs, use a consistent style, and learn from each other’s experience. We have “lab days” every other week as time dedicated to learning and experimenting with new ideas and technology. They are a good opportunity for us to take a risk and try something new!

  • Analyse, design, create and maintain robust, high-throughput data pipelines from our autonomous robots and their control system and peripherals (pick stations etc)
  • Populate new data stores to power statistical analysis and machine learning
  • Lead end-to-end investigations to troubleshoot data issues
  • Interact with other developers, product owners, analysts and data scientists
  • Assist Data Scientists with productionizing machine learning models

What we look for


  • 2:1 or higher degree in Computer Science, Maths, Physics, Engineering or similar highly numerate subject
  • Commercial, full-lifecycle development experience using Java/Scala and related tools (JUnit, Git etc)
  • A love of data and data flows as well as simple, maintainable, flexible code
  • Ability to apply and reason with basic statistics
  • Flexible in approach with the ability to learn fast


  • RDBMS and NoSQL datastores and querying
  • Python or other scripting language for tooling and data wrangling
  • Web front-end development (for internal apps)

  • Implementing machine learning models in production environments
  • BI tools like Tableau, Crystal Reports or Jasper
