SOC 2134 (85% match) is an eligible occupation, with a going rate of £54,700, and American Express is a licensed sponsor. That is our reading of the rules. Whether they issue a Certificate of Sponsorship is still their call.
This could also be SOC 2133 (IT business analysts, architects and systems designers, Role defines architecture and technical direction for AI platforms). We read the code off the advert, so it is our best guess, not the employer's.
