</ul>
CMC &amp; Regulatory Enablement
<ul>
<li>Contribute to and shape CMC downstream development strategies, including control strategy, in‑process monitoring, and operating ranges.</li>
<li>Author and review CMC‑relevant documentation (development reports, batch records, process descriptions).</li>
<li>Support preparation of regulatory submissions (e.g., IND).</li>
</ul>
Process Characterization, QbD &amp; Risk Management
<ul>
<li>Lead process characterization and platform studies, including DOE‑based investigations.</li>
<li>Apply QbD principles, risk assessments (e.g., FMEA), and scientific justification to define design space and control strategy.</li>
<li>Drive root cause investigations, troubleshooting, and continuous improvement initiatives.</li>
</ul>
Innovation &amp; Continuous Improvement
<ul>
<li>Identify and evaluate novel and next‑generation purification technologies (e.g., advanced chromatography, membranes, PAT/digital tools).</li>
<li>Champion platform evolution, efficiency gains, and robustness improvements aligned with long‑term modality strategy.</li>
</ul>
Documentation, Compliance &amp; Quality
<ul>
<li>Ensure development activities adhere to cGMP concepts, data integrity, and Quality Systems expectations.</li>
<li>Author and review protocols, reports, development summaries, and technical documents at a high standard of scientific and regulatory quality.</li>
<li>Interface closely with Quality to ensure inspection readiness and compliance.</li>
</ul>
Minimum Qualifications
Education
<ul>
<li>M.S. with 10+ years, or Ph.D. with 7+ years of hands‑on industry experience in downstream process development.</li>
</ul>
Technical &amp; Industry Experience
<ul>
<li>Extensive, hands‑on experience in LVV downstream process development (strongly preferred) or other viral vectors/biologics.</li>
<li>Deep expertise in clarification, chromatography, UF/DF (TFF), and sterile filtration.</li>
<li>Strong understanding of viral vector‑specific impurity profiles (HCP, host cell DNA, process residuals) and mitigation strategies.</li>
<li>Experience supporting clinical and/or commercial scale processes, including tech transfer.</li>
</ul>
CMC, GMP &amp; Regulatory
<ul>
<li>Proven working knowledge of cGMP principles, Quality Systems, and relevant FDA/EMA guidance for gene and cell therapies.</li>
<li>Direct experience contributing to CMC sections of regulatory filings.</li>
</ul>
Data, Statistics &amp; Risk Tools
<ul>
<li>Advanced experience with statistical analysis, DOE, and multivariate data interpretation.</li>
<li>Strong application of QbD, risk management, and process justification methodologies.</li>
</ul>
Leadership &amp; Collaboration
<ul>
<li>Excellent written and verbal communication skills.</li>
<li>Demonstrated ability to lead in matrixed environments, influence stakeholders, and resolve complex technical challenges.</li>
</ul>
Preferred Qualifications
<ul>
<li>Track record of scaling LVV or viral vector purification processes from preclinical through clinical and commercial‑relevant equipment.</li>
<li>Experience supporting technology transfer to GMP manufacturing sites and CDMOs.</li>
<li>Exposure to PAT, digital tools, and data/knowledge management systems.</li>
<li>Demonstrated success in building and delivering next‑generation purification processes end‑to‑end.</li>
