About the role:
We are a niche beauty startup dedicated to developing high-quality cosmetic products with a strong focus on natural ingredients and modern formulation science. We combine scientific standards with a conscious approach to sustainability, ingredient transparency, and performance-driven skincare.
So, what can you expect to work on?
Own incoming quality control for raw materials and packaging, including sampling plans, specification checks, and supplier certificate of analysis review.
Manage batch release: reviewing production records, in-process checks, and finished-product testing before a batch is cleared for sale.
Coordinate microbiological, stability, and preservative-efficacy (challenge) testing with external laboratories, and interpret results against acceptance criteria.
Lead investigation of out-of-specification results and contamination events, including root cause analysis, containment, and corrective and preventive action (CAPA) plans, in coordination with suppliers.
Maintain and continuously improve Standard Operating Procedures (SOPs) for quality control and quality assurance processes.
Own the customer complaint process: logging, root cause analysis, corrective action, and closing the loop with customer service and production.
Maintain quality records and documentation in line with ISO 22716 (Cosmetics GMP) principles.
Support internal audits of quality processes and prepare documentation for external audits and certification bodies.
Evaluate new raw materials and suppliers from a quality and testing perspective ahead of onboarding, working closely with Sourcing and Development.
Act as the day-to-day quality contact for Production and Development, flagging quality risks before they reach the market.
