Director Drug Product Formulation Development Jobs in Ridgefield, CT

This is what you will do:

The Scientist III will be a key member of the Injectable Drug Product Development (IDPD) team, responsible for drivingend-to-end drug product development-from candidate selection through commercial validation and regulatory filing-for parenteral/injectable biologic products. This role demands deepexpertiseinformulation development, process development, process engineering, scale-up modeling, and technology transfer,leveragingfirst-principles engineering, computational modeling, and simulation tools to deliver robust, scalable drug products.

You will apply strong process engineering fundamentals to design, model,optimize, and scale drug product manufacturing processes (e.g., mixing, filtration, fill/finish unit operations, hold steps, viscosity management). You will employ process modeling and simulation approaches (e.g., CFD, heat/mass transfer models, DoE-driven process models) to predict scale-dependent behavior, de-risk manufacturing, and support technology transfer to internal and external manufacturing sites.

You will provide scientific leadership for phase-appropriate formulation development of diverse biologic modalities-including monoclonal antibodies (mAbs), enzymes, enzyme fusion proteins, peptides, and AAV gene therapies-informed by biophysical and biochemical characterization data. You will integrate complex datasets to translate findings into formulation compositions, process parameters, control strategies, technical reports, and regulatory filings.

This position interacts regularly with cross-functional staff from Analytical Sciences & Quality Control, Drug Substance Process Development, Device Development, Manufacturing Technical Services, Quality Assurance, and CMC Regulatory Affairs.

You willbe responsible for:

• Data Integration & Control Strategy- Integrating complex datasets toestablishstructure-function relationships, degradation pathways, and mechanism-informed models; translating insights into robust formulations, control strategies, and phase-appropriate specifications.

• Regulatory & Documentation- Authoring protocols, technical reports, and contributing to CMC sections of regulatory submissions (e.g., IND/IMPD, BLA/MAA), including process descriptions, comparability assessments, and responses to regulatory queries.

• Cross-Functional Collaboration- Partnering with Analytical Sciences & QC, Drug Substance Process Development, Device Development, Manufacturing Technical Services, Quality Assurance, and CMC Regulatory Affairs to align development plans and ensure on-time program delivery.

• Team Leadership- Managing and mentoring junior team members in matrix teams; reviewing study designs and data; promoting experimental rigor and documentation excellence.

• Communication & Initiative- Presenting program status, risks, and recommendations clearly to senior management and cross-functional teams; taking initiative to solve scientific and operational challenges.

• Safety & Laboratory Operations- Operating primarily in a laboratory environment andcomplying withall safety procedures; with or without accommodation, able to lift/carry 15/30 pounds (unassisted/assisted) and workaround biological, infectious, and hazardous materials whilemaintaininga safe, orderly workspace.

You will need to have:
