This role likely qualifies for a Skilled Worker visa
SOC 2125 (85% match) is an eligible occupation, with a going rate of £45,000, and Stantec 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 2121 (Civil engineers, Water treatment engineering focus could fit civil engineers) or SOC 1123 (Production managers and directors in mining and energy, Technical leadership and business plan contributions could suggest management). We read the code off the advert, so it is our best guess, not the employer's.
