We’re currently building out our team to focus on the development of our own biomaterial technology: microbial weaving, a biofabrication process employing bacteria to grow customizable composite materials. Our goal is to provide truly sustainable + inspiring cellulose-based alternatives to reduce the industry’s dependence on petrochemical-derived materials—without sacrificing creativity.

We’re Hiring!

Are you excited to grow new materials with bacteria? We’re looking for a senior bioprocess engineer to design and operate pilot scale production equipment – increasing capacity and improving product quality. You’ll also support cutting edge R&D and academic collaborations to develop the future of biomaterial technologies. In addition, you’ll be working closely with the design team to produce innovative materials for customer projects with global fashion brands.
