Joining SII Ouest means thriving in a dynamic, human-scale agency where proximity meets friendliness and technology means expertise.
As a major player in the local ecosystem, we encourage technical exchanges and sharing. We are organisers, partners, and participants in tech events in the West. #BreizhCamp #24hducode #meetup
Our five sites have been renovated in recent years to offer functional and modern workspaces, designed to combine well-being and productivity. Moments of sharing, team meetings, after-work events, as well as sports and cultural associations, are an integral part of our DNA.
