Job Description

About Willow Biosciences: Willow Biosciences is a synthetic biology company focused on the development of biobased processes for the production of ingredients, including those for consumer care, food & beverage, and pharmaceuticals. Our scientists engineer organisms to produce plant-, animal-, and petrochemical-derived ingredients through precision fermentation. Our processes are more sustainable, secure, and cost-effective than traditional extraction or chemical synthesis routes and typically provide the final products in higher purity.

Job Listing: Research Associate – Strain Engineering

We are seeking an experienced Research Associate who will work under the guidance of Scientists focusing on metabolic engineering of biosynthetic pathways in microorganisms, particularly yeast. The successful candidate will have a strong work ethic, and the ability to effectively focus using practical experience working with synthetic DNA and gene-editing tools to create, clone, and deliver diverse DNA libraries.

Education: BS in genetics, molecular biology, microbiology, biochemistry, chemical engineering, or a related field.

Experience: 1-2 or more years of demonstrated experience in a high-throughput environment working with DNA library construction/cloning techniques (PCR, cloning, microbial transformation, homologous recombination, sequencing, and CRISPR-based integration), in an industrial research setting (Biotechnology, Pharmaceutical, or Life Sciences Industries).
