Research Associate – Bioprocess Development (Fermentation)

Location: 750 Main Street, Cambridge MA. 02139 (The majority of work will be on-site)

Employment status: Full-time position with a competitive compensation and benefits package

Concerto Biosciences

At Concerto Biosciences, we are obsessed with microbes. We dream of a healthier world where microbial ecology enables advanced medicines and environmentally-conscious agricultural practices. To unlock microbial ecology, Concerto uses a novel screening technology from MIT to construct and observe millions of microbial cocultures in parallel—each its own tiny universe of possibilities. Our technology generates a totally new type of microbiome data that allows us to identify groups of microbes that perform beneficial functions. We call these groups “ensembles”. We are currently in the preclinical stage for our first product, an ensemble to treat eczema—a chronic, irritating, and psychologically stressful skin disease that affects over two hundred million people. Our goal is to discover the first-ever treatment that provides totally safe, sustained relief for eczema patients. Concerto will go on to develop a multitude of ensembles that solve the world’s greatest challenges in human health, food production, and bioremediation.

The Concerto team is our most important ensemble. We believe the best human ensembles, much like microbial ensembles, are diverse—composed of individuals with different backgrounds, cultures, genders, and beliefs. We are committed to building a company where you belong and where your voice is heard.

Role Description

As a Research Associate – Fermentation, you will join Concerto’s effort to advance the development of microbial ensembles into products. Some characteristic responsibilities include: executing basic microbial fermentation techniques during bioprocess development toward the manufacturing of Concerto’s first live biotherapeutic product (LBP), “Ensemble No.2” (ENS-002); assisting with materials preparation and execution during fermentation runs; and supporting proper documentation of activities in the laboratory. You will need to be meticulous with your work, highly communicative, and able to work closely with a team.

This role will require laboratory experience in microbiology and fermentation of LBPs. We don’t expect you to have experience performing all of the responsibilities listed below. Indeed, just as you help Concerto grow, we hope to contribute to your intellectual and professional growth. You’ll have the opportunity to gain new skills by working with our world-class team, and you’ll also have the opportunity to advance within the company by taking on higher responsibility roles. As an early member of Concerto’s expanding team, you’ll play a critical role in developing Concerto’s culture and translating our core values into practice.
