Job description

Who are we?

Ogi is on a mission to power up life online for homes, businesses and communities across South Wales, installing real fibre right up to your doorstep. In October 2020, we secured landmark multi-million-pound funding to deliver a large-scale and ambitious rollout of full fibre broadband across South Wales. We believe that joining Ogi is a unique opportunity to work within an innovative Welsh business and one of the fastest-growing companies in Wales. Until now, the pace of levelling up Wales’s broadband infrastructure has been too slow - So we plan to speed things up.

This is a unique opportunity to join an innovative company in a fast-growing sector and help our talented team build a leading Welsh tech business - one that will make a crucial difference to the people and places we serve.

Working closely with the Field Network Engineering Team, NOC and Provisioning teams, you will contribute to maintaining service excellence while developing your knowledge of network operations within one of Wales' fastest-growing fibre providers. The successful candidate will be safety-conscious, detail-oriented and committed to delivering an exceptional customer experience.
