About the vacancy

Our client is a big online retailer with yearly revenue of £1 billion. We have a long history of relationships and over the years have helped this customer to develop web-portals and mobile apps, delivery control systems, staff management tools, data storage, etc.

The Java Developer that we are searching for will join a team that develops software for an automated orders fulfillment center.

The system consists of a large number of applications installed in warehouses and responsible for different parts of the orders fulfillment pipeline. The system orchestrates the highly efficient routing of goods in warehouses, making sure that every item is at an exact place at an exact time, provides integration with hardware installed on-site and exchanges data with other systems. It is also constantly monitored and optimized to reduce the amount of necessary intervention and minimize the chance of failure.

The system is live, business-critical, and running 24/7, so the focus is now on optimization and improving the reliability, for which a number of Site Reliability Engineering best practices are being used.

The teams are primarily based in the UK and consist of experienced engineers who know and understand the system well. They constantly work with the business to suggest and implement new solutions and address known problems.
