Director of Formulation Chemistry

We offer opportunities to do your life’s work while helping solve one of the most important technical and moral challenges of our time.

Full-time, in-office in Emeryville, California. Compensation includes equity.

You’ll translate our hit repellent compounds from milligram-scale discoveries into pilot and manufacturing scale formulations. You’ll optimize solvent systems, work on controlled release systems, and ensure robust, reproducible processes for field trials and commercial production.

Key Responsibilities

• Lead bench-to-pilot scale-up of candidate compounds, focusing on solvent selection, solvent recovery, controlled release, and other critical scale-up variables


• Design and execute experiments to assess solubility, stability, and volatility


• Troubleshoot formulation issues and iterate quickly under real-world constraints


• Collaborate cross-functionally with predictive-modeling, behavioral assay, and computational chemist groups

Qualifications

• M.S. or Ph.D. in Organic Chemistry, Chemical Engineering, or related field


• 3+ years’ hands-on scale-up or process chemistry experience


• Deep understanding of solvent properties, controlled release phenomena, and formulation principles


• Track record of developing robust, reproducible processes


• Strong data analysis, documentation, and troubleshooting skills

Desired Attributes

• Entrepreneurial mindset: thrives in ambiguity and high-pressure environments


• Resilient problem-solver: tackles “hardest things” head-on


• Communicates clearly, honestly, and respectfully


• Collaborative spirit
