SOC 2124 (73% match) is an eligible occupation, with a going rate of £52,000, and Plessey Semiconductors Ltd 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 2123 (Electrical engineers) or SOC 2129 (Engineering professionals not elsewhere classified). We read the code off the advert, so it is our best guess, not the employer's.
