But despite being geographically spread, we are strategically united in changing the price-promotion game for good. We work in small teams with fast feedback loops, which enables us to “get stuff done” and work on challenging problems. Because our team comes from all over the world, our company language is English, (but you might hear the odd German, Russian or Spanish conversation).

At Segment of One, we keep the office environment alive in remote locations by meeting for a virtual coffee and meeting up at exciting offsite locations across Europe every six weeks (in normal times).

As an equal opportunity employer, we welcome applications from candidates regardless of race, religion, gender identity, sexual orientation, age, disability, or background.
