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
