Human Safety Expert

Bayer•Chesterfield, MO

1d•$120,560 - $180,840

About The Position

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.

Requirements

M.S. in Exposure Science, Toxicology, Environmental Health, Industrial Hygiene, Pharmacology, Chemistry, or a related field
Demonstrated delivery of exposure and risk assessments and successful interactions with regulatory agencies in support of pesticide registrations
Deep expertise in hazard characterization and occupational, residential, dietary, aggregate, and cumulative exposure assessment and higher‑tier exposure modeling approaches
Strong technical writing skills with the ability to synthesize complex evidence into defensible, regulator‑ready documents
Proven ability to lead multiple complex scientific projects, prioritize in a dynamic environment and provide technical leadership and strategic direction across human safety disciplines
Excellent communication, organizational and interpersonal skills with a track record of influencing cross‑functional teams and stakeholders

Nice To Haves

Ph.D. in Exposure Science, Toxicology, Environmental Health, Industrial Hygiene, Pharmacology, Chemistry, or a related field with 8+ years of relevant experience; OR M.S. in Exposure Science, Toxicology, Environmental Health, Industrial Hygiene, Pharmacology, Chemistry, or a related field with 12+ years of directly relevant experience
Experience supporting global human safety pesticide regulatory submissions and familiarity with agrochemical regulatory toxicology, study requirements, and interpretation of results
Experience with analytics‑driven exposure systems, novel methodological or algorithmic approaches, and direct experience engaging with EPA/PMRA/APVMA regulatory processes

Responsibilities

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
