Senior Eye Make-Up Product Developer (Advisory)

About The Team

We're building for the 50+ consumer: an underserved, ingredient-literate audience that expects products to genuinely perform. As an early-stage, well-funded venture moving quickly, we're looking for a Senior Eye Make-Up Product Developer to join us in an advisory capacity. Your expertise will help shape our eye category, influence key product decisions, and guide development from concept to launch.

• Shape the future of a new pro-age beauty brand built for the 50+ consumer
• Advise on the development of high-performance eye make-up products, from concept through launch
• Work directly with founders, influencing key product and technical decisions from day one
• Bring technical expertise to supplier and manufacturer conversations, ensuring the highest product standards
• Help build a product portfolio that genuinely serves an overlooked consumer segment
  
  

We expect you to

• Lead technical advisory across the eye make-up category, including mascara, eyeliner, brow products, and adjacent innovations
• Guide formulation strategy, ingredient selection, performance targets, and commercial trade-offs.
• Advise on product assortment, claims, shades, and category expansion based on deep industry expertise
• Design and oversee product validation programmes, including wear testing, ophthalmologist testing, consumer panels, stability studies, and PET
• Evaluate manufacturers' technical proposals and challenge recommendations when needed
• Support sourcing and selection of contract manufacturers and raw material suppliers
• Stay ahead of EU cosmetic regulations, ingredient developments, claim substantiation requirements, and emerging clean beauty trends
• Share practical expertise gained from developing and launching successful colour cosmetic products
• Collaborate confidently with cross-functional teams in English within a fast-moving, entrepreneurial environment
• Contribute as a trusted strategic advisor while remaining hands-on during critical product development milestones
  
  

Salary

This is a part-time advisory role. Roughly 2-3 days per month to start, with flexibility to scale up during active development phases.
