Senior Bioprocess Scientist/Engineer

Boston Bioprocess Inc. is a bioprocess optimization company; our mission is to help optimize bioprocesses helping precision fermentation businesses develop, optimize, and scale their production processes. Our company does this by combining hands-on work at our bench lab and pilot-scale facilities with the use of AI-powered optimization software. We are seeking a highly motivated Senior Bioprocess scientist or Bioprocess engineer to join our team.

The Senior Bioprocess Scientist/Engineer will work closely with the CSO and data science teams. The right candidate has substantial lab and/or plant experience across diverse bioprocesses and microbial systems, a strong command of software tools, and an enthusiasm for software development.

This role leads all efforts to support the development and improvement of our AI-powered optimization software for fermentation and purification processes at bench, pilot, and production scale. Responsibilities include designing experiments and generating data to enhance bioprocess parameters for proteins, lipids, amino acids, organic acids, polysaccharides, hydrocolloids, and enzymes across bacterial, yeast, and fungal systems.

While highly technical, the role requires regular engagement with clients, research organizations, and CDMO partners. Prospective candidates should understand that success requires technical expertise, but it also involves empathy, prompt communication, and a general client-service orientation.

Job Responsibilities

• Lead and manage bioprocess development projects, ensuring timely delivery and successful outcomes; provide technical expertise and guidance on experimental planning, process development, and troubleshooting
• Design, execute, and troubleshoot experiments to optimize and scale-up fermentation and purification processes across bacterial, yeast, and fungal hosts for a range of products including proteins, lipids, amino acids, organic acids, polysaccharides, hydrocolloids, and enzymes
• Act as a key liaison between the bioprocess and data science teams
• Generate and analyze data to drive improvement of our AI-powered optimization software; prepare technical reports and presentations for internal and external stakeholders
• Monitor industry trends, emerging technologies, and regulatory requirements in bioprocessing and apply insights to process and software optimization
• Mentor junior scientists and engineers, providing technical guidance and supporting their professional development
• Identify and lead initiatives to improve company workflows and operational excellence
