Job Description

Human Safety Expert

YOUR TASKS AND RESPONSIBILITIES

The purpose of this position is to provide hazard, non-dietary exposure, and risk assessment expertise in support of product safety for Bayer Crop Science NAANZ. Position responsibilities include the collection, evaluation, and dissemination of product-related hazard, non-dietary exposure and risk information, and the application of multi-route, multi-source aggregate and cumulative human exposure and risk assessment models. The individual in this position will work with non-dietary exposure and risk assessment, as well as regulatory toxicology experts within the Human Safety department to develop occupational and residential product safety assessments for product registration and defense. Success in this position requires the understanding and application of human hazard, exposure, and risk assessment principles to the conduct of human safety assessments associated with agricultural and residential pesticide use.

The primary responsibilities of this role, Human Safety Expert, are to:

• Evaluate human safety positions, toxicology and human exposure, and recommend risk‑management strategies to refine risk assessments and reduce worker exposure while protecting product registration and commercial outcomes;
• Provide subject‑matter expertise for hazard, occupational, residential, dietary, aggregate, and cumulative risk assessments and align that expertise with functional objectives to drive improved study designs and higher‑tier assessments supporting global registrations;
• Plan, design, and provide strategic direction for non‑dietary occupational and consumer exposure studies, ensuring scientific quality, cost effectiveness, and compliance with regulatory guidelines and evolving scientific standards;
• Conduct deterministic and probabilistic dietary and non‑dietary exposure and risk assessments and develop/refine higher‑tier assessments for consumers, applicators, mixers/loaders, and other worker populations across agricultural and non‑agricultural uses;
• Serve as an active member of the Human Safety team, providing technical consultation and strategic direction to internal stakeholders and to regulatory agencies (EPA, PMRA, APVMA) on human health and exposure for product registrations;
• Accelerate development of analytics‑driven exposure science systems, including database management, statistical and probabilistic model analysis, and recommend study designs, data needs, and new methodological approaches;
• Support BCS and industry initiatives to shape national and international regulatory policy on human health, exposure and occupational/consumer safety and champion sound science, realistic exposure scenarios and risk‑based decision making;
• Operate across the BCS global network as a technical expert to ensure consistent scientific approaches, knowledge sharing and cross‑regional alignment.
