You will take full commercial ownership of our Cosmetics & Personal Care segment and turn technical validation into visible, 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.

Escalate structural commercial decisions appropriately. Qualifications: Degree in chemistry, formulation science, materials science, or related field. 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. 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 to someone who needs heavy corporate infrastructure. Why Join: Join a scaling deep-tech company transitioning from validation to industrial production, with the opportunity to shape 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 in an interdisciplinary team combining science, engineering, and commercial execution.
