As the UK's most successful omni-channel retailer, ecommerce is a key part of our business - we run two of the busiest websites in the UK, driving a significant proportion of our sales. Our engineering practice includes 80+ teams, working on everything from Cloud platforms to mobile apps, from ecommerce functionality to machine learning.

However, there will also be an expectation to visit other locations as the need arises. Our Engineering team currently works from the office roughly once a week to connect and on a more ad-hoc basis to attend key meetings, but again the frequency is dependent on the business needs.
