* Evaluate and interpret GLP-compliant ecotox studies; contribute to study planning, monitoring, and contracting with CROs.
* Use regulatory tools such as FOCUS, EFSA PRIMo, and IUCLID for exposure modeling and data submission.
* Support and/or lead active substance renewal and defense dossiers; prepare waivers, data gap justifications, and scientific argumentation.
* Provide scientific input for product registrations where active substance data is not required.
* Interface with regulatory authorities in the EU; contribute to regulatory strategy development and participate in response preparation to authority questions.
* Assist LATAM regulatory teams with data interpretation, dossier compilation, and strategic planning (~20% of workload).
Profile We’re Looking For
* MSc or PhD in Ecotoxicology, Environmental Sciences, Agricultural Sciences, Chemistry, or similar.
* Minimum 3+ years' experience in regulatory ecotoxicology within the agrochemical industry, consultancy, or regulatory authority.
* Solid experience with EU regulatory frameworks for active substances and/or plant protection products.
* Proficient in risk assessment methodologies, dossier preparation, and ecotoxicological study interpretation.
* Familiarity with regulatory tools (e.g., FOCUS models, PRIMo, EU IUCLID, OECD/EU test guidelines).
* Active substance registration experience strongly preferred; product-only experience will also be considered.
* Experience working with or supporting LATAM registrations is a plus.
* Fluent in English; additional language skills (German, Spanish, Portuguese) are advantageous but not essential.
