What a licence means
They can sponsor. That is all it says.
A sponsor licence lets an organisation assign a Certificate of Sponsorship to a worker on the routes it covers. It does not mean S3 Alliance UK LTD is hiring from abroad this month, only that it can, and has been checked by the Home Office to do so.
How to approach them
Lead with the role, not the visa
Apply through the careers page or the job boards with a UK-style CV, say early that you would need sponsorship, and make the skill and the years the first thing they read.
