Position Summary

The Staff Scientist – Peracetic Acid (PAA) Formulation & Optimization is a senior technical contributor responsible for the development, optimization, and commercialization support of peracetic acid–based formulations across multiple end-use applications. This role focuses on innovation, improving formulation performance, stability, safety, cost, and regulatory compliance while supporting scale-up, manufacturing, and customer implementation.

The position requires deep expertise in oxidative chemistry, formulation science, and applied problem-solving, with close collaboration across R&D, Regulatory, EHS, Manufacturing, Supply Chain, and Commercial teams.

Key Responsibilities

• Lead formulation design, optimization, and troubleshooting of peracetic acid and other direct food contact products, including sanitizers, disinfectants, antimicrobial process aids, and specialty oxidizing formulations

• Optimize PAA formulations for performance, manufacturability, stability, shelf life, material compatibility, and controlled reactivity

• Evaluate raw materials (acids, peroxides, stabilizers, chelants, surfactants) for performance, cost, supply robustness, and regulatory acceptability

• Design and execute laboratory experiments to assess kinetics, equilibrium, degradation pathways, and performance under real-world use conditions

• Provide expert guidance on formulation limits driven by chemistry, physics, equipment, and safety constraints

• Support pilot- and plant-scale trials, including technology transfer to manufacturing.

• Troubleshoot manufacturing issues related to PAA generation, stability, heat release, compatibility, and dosing accuracy

• Partner with Process Technology and Operations to define safe operating windows, equipment requirements, and process controls

• Support customer trials, field evaluations, and issue resolution for PAA-based systems

• Collaborate with EHS and Regulatory teams to ensure formulations meet global regulatory, labeling, transport, and safety requirements

• Support hazard evaluations, thermal stability assessments, and safe handling guidance for PAA and related oxidizers

• Drive formulation improvements to reduce cost, improve supply resilience, and enable value-engineering opportunities

• Support cost modeling, raw material qualification, and alternate supplier evaluations

• Act as a subject-matter expert in peracetic acid chemistry across R&D and commercial teams

Qualifications

• MS or PhD in Chemistry, Chemical Engineering, or a related scientific discipline

• Minimum 7–10 years of industrial experience in formulation chemistry, with significant hands-on experience in peracetic acid or peroxide-based systems

• Strong understanding of oxidation chemistry, reaction kinetics, stability mechanisms, and formulation interactions

• Experience supporting scale-up, manufacturing, and commercialization of chemical formulations
