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 from cellulose, the world’s most abundant biopolymer. Our mission is to create 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 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 driven individual who is ready to take ownership of a segment and convert technical innovation into market adoption. In this role, you will have full commercial responsibility for our Cosmetics & Personal Care segment, transforming technical validation into visible, revenue-generating success. This position is not about distributor management nor corporate account management; it is a hands-on, high-impact commercial role within 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 significant market adoption.

Responsibilities:

  • Build the Cosmetics Commercial Engine:
    • Own and prioritise the cosmetics pipeline.
    • Convert 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 formulation support.
    • Collaborate closely with product development to accelerate validation.
    • Support customers through testing, iteration, and launch.
  • Be Disciplined in a Startup Environment:
    • Focus on customers that drive impactful results.
    • Decline opportunities that dilute focus.
    • Protect pricing and avoid unnecessary exclusivity.
    • Escalate structural commercial decisions appropriately.

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 well-recognized cosmetic brands.
  • Strong negotiation capability and commercial judgment.
  • Self-directed and comfortable owning a segment 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 heavy corporate infrastructure.

Why Join:

  • Join a scaling deep-tech company transitioning from validation to industrial production, and influence how a new class of materials enters global markets.
  • Contribute to building a new materials platform from early market adoption to large-scale production.
  • Work in an interdisciplinary team combining science, engineering, and commercial execution.
  • Gain direct exposure to leadership and strategic decision-making.
