About the role

At Tesco, we believe in the power of spending more time together, face to face, than apart. So, during your working week, you can expect to spend 60% of your time in one of our office locations or local sites and the rest remotely. We also recognise that life looks a little different for each of us. Some people are at the start of their careers, some want the freedom to do the things they love.

That’s why at Tesco, we always welcome a conversation about flexible working. So, talk to us throughout your application about how we can support.
