We know life looks a little different for each of us. That's why at Tesco, we always welcome chats about flexible working. Some people are at the start of their careers, some want the freedom to do the things they love. Others are going through life-changing moments like becoming a carer, nearing retirement, adapting to parenthood, or something else. So, talk to us throughout your application about how we can support. Are you an Operational Research specialist with strong Meta-heuristics experience? Then look no further and come and join our team! We'd love to hear from you if you have any questions about the role or our team.
