Contract, outside IR35. Manchester-based client, starting as soon as possible. The engagement You'll lead engineering on a high-volume online marketplace, part-way through a major, multi-year technology transformation. A version 2 build is underway, and a move to AWS is under active evaluation as part of that. The current client-facing platform runs on PHP and Laravel.
