• Ensure highquality experimental design execution data interpretation and timely communication of results.

ScaleDown Models ScaleUp & Technology Transfer

• Design and qualify representative scaledown models to support process characterization and comparability.

• Support scaleup to pilot clinical and commercialrelevant equipment and consumables.

• Author review and approve technology transfer packages and support successful implementation at internal GMP sites and external CDMOs.

CMC & Regulatory Enablement

• Contribute to and shape CMC downstream development strategies including control strategy inprocess monitoring and operating ranges.

• Author and review CMCrelevant documentation (development reports batch records process descriptions).

• Support preparation of regulatory submissions (e.g. IND).

Process Characterization QbD & Risk Management

• Lead process characterization and platform studies including DOEbased investigations.

• Apply QbD principles risk assessments (e.g. FMEA) and scientific justification to define design space and control strategy.

• Drive root cause investigations troubleshooting and continuous improvement initiatives.

Innovation & Continuous Improvement

• Identify and evaluate novel and nextgeneration purification technologies (e.g. advanced chromatography membranes PAT/digital tools).

• Champion platform evolution efficiency gains and robustness improvements aligned with longterm modality strategy.

Documentation Compliance & Quality

• Ensure development activities adhere to cGMP concepts data integrity and Quality Systems expectations.

• Author and review protocols reports development summaries and technical documents at a high standard of scientific and regulatory quality.

• Interface closely with Quality to ensure inspection readiness and compliance.

Qualifications

Education

• M.S. with 10 years or Ph.D. with 7 years of handson industry experience in downstream process development.

Technical & Industry Experience

• Extensive handson experience in LVV downstream process development (strongly preferred) or other viral vectors/biologics.

• Deep expertise in clarification chromatography UF/DF (TFF) and sterile filtration.

• Strong understanding of viral vectorspecific impurity profiles (HCP host cell DNA process residuals) and mitigation strategies.

• Experience supporting clinical and/or commercial scale processes including tech transfer.

CMC GMP & Regulatory

• Proven working knowledge of cGMP principles Quality Systems and relevant FDA/EMA guidance for gene and cell therapies.

• Direct experience contributing to CMC sections of regulatory filings.

Data Statistics & Risk Tools

• Advanced experience with statistical analysis DOE and multivariate data interpretation.

• Strong application of QbD risk management and process justification methodologies.

Leadership & Collaboration

• Excellent written and verbal communication skills.

• Demonstrated ability to lead in matrixed environments influence stakeholders and resolve complex technical challenges.

Preferred Qualifications

• Track record of scaling LVV or viral vector purification processes from preclinical through clinical and commercialrelevant equipment.

• Experience supporting technology transfer to GMP manufacturing sites and CDMOs.

• Exposure to PAT digital tools and data/knowledge management systems.

• Demonstrated success in building and delivering nextgeneration purification processes endtoend.
