About the role

Work closely with internal and external cross‑functional teams to make sure all technical milestones are met throughout the project.
Coordinate factory line trials and oversee the required R&D qualification testing and validation before product launch.
Ensure all product specifications and internal documentation are fully completed, approved, and ready ahead of full production start‑up.
Stay consumer‑focused by understanding behaviours and preferences across different regions, and translate these insights into meaningful product design and development decisions.
Balance formulation and product performance needs while meeting challenging cost targets.
Develop strong and repeatable evaluation methods that support credible, consumer‑relevant product claims.
Consider all intellectual property requirements throughout the development process to protect innovation.
Prepare, approve, and circulate clear technical reports at each stage of product development.
Ensure all development activities comply with legislative, health & safety, and environmental standards.
If applicable, provide guidance and line management support to one or more R&D Assistants, helping them grow and develop in their roles.

Hands‑on experience with formulation, process development, or product testing, including lab work and data analysis.

A relevant scientific discipline such as Chemical Engineering, Chemistry, Sciences, Biochemistry, Biomedical Sciences, or Cosmetic Formulation
