Senior Technical Sales Manager – Lead Market Adoption of Breakthrough Cosmetic and Personal Care Ingredients

About Seprify

Headquartered in Marly (CH), Seprify AG was founded in 2022 as a spin-out from the University of Cambridge and the University of Fribourg. We develop high-performance ingredients derived from cellulose, the world’s most abundant biopolymer.

We are pioneering a new class of light-scattering, high-performance materials designed to replace conventional polymeric and mineral-based functional ingredients across various industries. As a scaling deep-tech company, we blend scientific excellence with entrepreneurial execution.

This role offers significant ownership, direct exposure to leadership, and the exciting 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 seeking a dynamic individual who is eager to take ownership of a segment and convert technical innovation into tangible market adoption. You will have full commercial ownership of our Cosmetics & Personal Care segment, driving technical validation towards visible, revenue-generating market adoption. This is a hands-on, high-impact commercial role in a growing materials company, distinctly separate from distributor management or corporate account management functions.

You will operate at the intersection of science and business, collaborating directly with formulators, brands, and our internal technical team to facilitate substantial market adoption.

Responsibilities

• Build the cosmetics commercial engine.
• Own and prioritize the cosmetics pipeline.
• Turn testing results into repeatable commercial sales.
• Secure commercial sales with visible reference customers.
• Drive negotiations and close structured commercial agreements.

Translate Science into Revenue

• Present confidently to external R&D and formulation teams.
• Translate performance data into valuable formulation support.
• Collaborate closely with product development to speed up validation.
• Support customers through testing, iteration, and launch phases.

Be Disciplined in a Startup Environment

• Focus on customers that significantly impact the bottom line.
• Say "no" to opportunities that dilute focus.
• Protect pricing and avoid unnecessary exclusivity agreements.
• Escalate structural commercial decisions as needed.

Qualifications

• Degree in chemistry, formulation science, materials science, or a related field.
• 5-10+ years of experience in cosmetics & personal care sales or specialty ingredients.
• Proven track record of converting technical validation into commercial agreements.
• Experience working directly with formulators and/or recognized cosmetic brands.
• Strong negotiation skills and commercial judgement.
• Self-directed and comfortable taking ownership in a lean, scaling environment.

What This Role Is Not

• Not a junior account management position.
• Not a pure applications scientist role.
• Not a volume-driven territory sales role.
• Not suited for individuals who require a heavy corporate infrastructure.

Why Join Us

Join a scaling deep-tech company transitioning from validation to industrial production, with the opportunity to influence how a new class of materials enters global markets. Be part of building a new materials platform from early market adoption to large-scale production.

Work within an interdisciplinary team that combines science, engineering, and commercial execution while enjoying direct exposure to leadership and strategic decision-making.
