- Support the preparation and maintenance of regulatory and safety documentation, including dossiers, safety summaries, and responses to regulatory or customer inquiries.
- Maintain toxicology databases and documentation, collaborate with cross-functional teams, and stay up to date on global chemical and food regulatory requirements.
What you’ll bring:
- Bachelor’s or Master’s degree in Toxicology, Pharmacology, Chemistry, Biochemistry, or a related scientific discipline.
- 0–2 years of relevant experience in toxicology, regulatory affairs, product stewardship, or related areas (including academic projects or internships).
- Foundational knowledge of toxicology and toxicokinetics (ADME) and exposure-based risk assessment across key endpoints (e.g., acute and repeated dose toxicity, genotoxicity, carcinogenicity, reproductive and developmental toxicity).
- Basic understanding of food ingredient and chemical regulations, such as EU REACH, CLP, Cosmetics Regulation, Food Contact Materials, or similar global frameworks.
- Strong organizational and project management skills, with the ability to manage data, work with regulatory databases, and communicate effectively across teams.
