Data Scientist

Colleague Networks – internal groups where colleagues and their allies can share their own experiences, offer feedback on the way we do things at Greggs, and provide support to one another. This is a full‑time role, however flexibility in this will be considered. We know that having a work‑life balance is important, so we offer our colleagues as much flexibility as possible in line with the needs of their role. The base location for this role is Newcastle Upon Tyne.
