How to Apply for Director, Protein & Cell Sciences

at Flagship Pioneering

🏢 About Flagship Pioneering

Flagship Pioneering is a unique venture creation firm that conceives, creates, resources, and grows first-in-category life sciences companies. Unlike traditional biotech companies, Flagship operates through its 'explore, prototype, and scale' model, giving employees the opportunity to work on groundbreaking platform technologies from inception. Metaphore (the company mentioned in the job description) appears to be one of these ventures, focused on developing transformative therapeutics through an innovative platform.

About This Role

As Director of Protein & Cell Sciences, you'll lead a team responsible for high-throughput antibody/protein production and cell culture scale-up to multi-gram levels, directly supporting multiple biologics discovery programs. This role is critical for establishing and maintaining the protein sciences function that enables Metaphore's platform to deliver transformative therapeutics to patients. You'll manage both internal teams and external CRO relationships while implementing automation solutions for efficiency.

💡 A Day in the Life

A typical day involves reviewing high-throughput protein production data with your team, troubleshooting purification challenges, coordinating with CROs on outsourced activities, and meeting with discovery program leads to align on reagent needs. You'll spend significant time optimizing workflows, implementing automation solutions, and ensuring your team delivers high-quality antibodies to support multiple simultaneous platform optimization efforts.
