About Seprify
Headquartered in Marly (CH), Seprify AG, founded in 2022 as a spin‑out from the University of Cambridge and the University of Fribourg, develops high‑performance ingredients from cellulose, the world’s most abundant biopolymer. We are building a new class of light‑scattering, high‑performance materials designed to replace conventional polymeric and mineral based functional ingredients across industries. We are a scaling deep‑tech company combining scientific excellence with entrepreneurial execution. This role offers significant ownership, direct exposure to leadership and the opportunity to shape a growing commercial engine.
Role Overview
Position: Senior Technical Sales Manager – Cosmetics & Personal Care
Location: Europe (flexible)
Type: Full‑time
We are looking for someone who wants to take ownership of a segment and turn technical innovation into visible market adoption. You will take full commercial ownership of our Cosmetics & Personal Care segment and turn technical validation into revenue‑generating market adoption. This is not a distributor management role and not a corporate account manager position. It is a hands‑on, high‑impact commercial role in a growing materials company. You will operate at the intersection of science and business, working directly with formulators, brands, and our internal technical team to drive visible market adoption.

5-10+ years’ experience in cosmetics & personal care sales or specialty ingredients.
Demonstrated track record of converting technical validation into commercial agreements.
Experience working directly with formulators and/or recognised cosmetic brands.
Strong negotiation capability and commercial judgement.

Not a pure applications scientist role.
Not a volume‑driven territory sales role.
Not suited to someone who needs heavy corporate infrastructure.

Be part of building a new materials platform from early market adoption to large‑scale production.
Work in an interdisciplinary team combining science, engineering and commercial execution.
Direct exposure to leadership and strategic decision‑making.
