Fermentation Research Associate II/III

Aralez Bio
Berkeley, CA Full Time
POSTED ON 4/14/2026
AVAILABLE BEFORE 5/10/2026
About the Company

We envision a world where we continuously, sustainably, and affordably improve human life with synthetic biology. Our proprietary set of enzymes and our manufacturing approach enables the production of thousands of amino acids that were previously too difficult and expensive to make. These "noncanonical" amino acids that we make are already catalyzing the creation of revolutionary and innovative products that are good for people and the planet.

Our technology outperforms traditional manufacturing approaches by 10–100x across the board. We already sell products to Big 10 Pharmaceutical companies, and our product family includes the key components of multi-billion dollar blockbuster drugs such as Ozempic and Mounjaro.

We are a diverse, passionate, interdisciplinary team that finds joy in building something new that leaves the world better than we found it. We strive to always learn and improve and have a deep desire to capitalize on our creativity and be exceptional at what we do.
