Here's how you will contribute:

• Support Drug Substance process development and manufacturing activities (e.g., upstream expression, purification, UF/DF, viral clearance)
• Design and execute scale-up, process characterization, and PPQ-enabling studies
• Own tech transfer and support GMP campaigns at CDMO (person-in-plant support as needed)
• Review and/or author GMP documentation including batch records, change controls, deviations and CAPAs
• Provide technical leadership for GMP manufacturing, including troubleshooting and data-driven decision making
• Partner cross-functionally across CMC, QA, Regulatory, and Supply Chain to drive program execution
• Drive continuous process improvement and process robustness initiatives
• Leverage AI-driven tools for knowledge management and data analysis to enable efficient and scalable CMC workflows

The Ideal Candidate will have:

• PhD or MS in Chemical Engineering, Biochemistry, or related field with relevant industry experience in biologics manufacturing
• 5–8 years of industry experience in Drug Substance process development and/or GMP manufacturing in a biotech/pharma setting
• Strong attention to detail with the ability to analyze complex technical data
• Excellent communication and strong technical writing skills
• Experience working with CDMOs, supporting tech transfer, and regulatory submissions
• Hands-on experience with GMP documentation (eg: executed Batch Records) and quality systems (deviations, change control, CAPA)
• Demonstrated ability to lead complex technical programs and collaborate effectively in cross-functional teams.
• Familiarity of regulatory issues pertaining to the manufacture of biologics, process validation, QbD principles and industry trends

Nice to Have (Optional)

• Experience supporting BLA/IND submissions.
• Exposure to accelerated development environments for early to late-stage program transitions

Location: This role is based out of Somerville, MA with flexibility for hybrid work (1-2 days a week in the office).

About Generate Biomedicines

We are a clinical-stage generative biology company pioneering the AI revolution in drug design and development. We are advancing a new approach to drug creation—one grounded in the ability to design proteins with defined biological intent. By integrating machine learning with large-scale experimentation, this approach aims to reduce the uncertainty, time, and cost associated with developing protein-based medicines.

Founded in 2018, we are advancing a growing pipeline of clinical and preclinical programs across multiple disease areas and protein modalities. By unifying computational design and clinical development within a single operating model, we translate this approach into clinical-stage programs and are leading a shift from traditional drug discovery toward systematic drug generation.

At Generate:Biomedicines, we collaborate across disciplines in new ways to invent and innovate. We bring diverse perspectives to a shared goal of delivering better medicines to patients in need, faster, guided by our values and leadership behaviors.
