With a robust pipeline of differentiated monoclonal antibody programs in and approaching CMC development, we are building the foundational infrastructure to bring these therapies to patients.

The Role

Reporting to the Chief Technology Officer, the Head of CMC will serve as the senior leader responsible for Chemistry, Manufacturing, and Controls technical operations and contract manufacturer management across our growing therapeutic antibody pipeline. This individual will define and execute CMC strategy from early development through IND-enabling activities and into the clinic, working cross-functionally with discovery, preclinical development, regulatory, and clinical teams, both full-time and consulting. This role is in-person at our Alameda, CA headquarters.

• Establish CMC policies, SOPs, and quality systems appropriate for a growing biotech
• Serve as key technical contributor to CMC scope of work and quality plan agreements with CDMOs
• Serve as the CMC subject matter expert on the leadership team, contributing to pipeline decisions, board presentations, and investor/partner communications
• Oversee cell line development, upstream bioprocess development, and downstream purification strategies for IgG-based antibody therapeutics
• Lead formulation development for high-concentration antibody drug products (=150 mg/mL) intended for subcutaneous administration
• Oversee DS and DP stability plan development, with input and approval from QA/QC
• Recruit and manage quality, regulatory, and other consultants as necessary
• Manage device selection, compatibility studies, and human factor considerations for syringe or autoinjectors in partnership with vendors
• Direct the development and qualification of analytical methods for drug substance and drug product, including stability-indicating assays
• Ensure all CMC activities are conducted in accordance with GxP expectations appropriate to development stage
• Review source documents from CDMOs, review and approve ATMs and MDRs; author and review CMC sections of INDs and related regulatory submissions; serve as primary CMC contact with regulatory agencies

Qualifications

Required

• Ph.D. in Chemical Engineering, Biochemistry, Pharmaceutical Sciences, or a related field; or M.S./B.S. with commensurate industry experience
• 12+ years of experience in biopharmaceutical CMC development, with a strong focus on monoclonal antibodies or related molecules
• Demonstrated experience developing high-concentration antibody formulations for subcutaneous delivery
• Significant experience managing CDMO relationships and overseeing GMP manufacturing campaigns
• Hands-on experience with successful IND filings and regulatory interactions as CMC lead
• Comfortable operating as the sole CMC expert in a small company, making judgment calls without complete data, and working with senior leadership.

Preferred

• Experience with autoimmune or inflammatory disease indications
• Familiarity with combination product regulatory frameworks (21 CFR Part 3, FDA CDER/CDRH coordination)
