Working at Sephora’s Field Support Center (FSC)

At the FSC, we support our stores in providing the best possible experience for every client. Dedicated teams cater to our client’s every need by creating covetable assortments, curated content, compelling storytelling, smart strategy, skillful analysis, expert training, and more. It takes a lot of curious and confident individuals, disrupting the status quo and taking chances. The pace is fast, the fun is furious, and the passion is real. We never rest on our laurels. Our motto? If it’s not broken, fix it.
