Senior Process Engineer, Manufacturing Sciences & Technology, Cell Therapy

This position focuses on ensuring robust, compliant, and cost-effective manufacturing of clinical and commercial cell therapy products.  
 

Responsibilities include leading on-the-floor / hands-on technical support, developing technical instructions, procedures, and operator training content, performing data analysis and process performance trending, leading complex deviation investigations, driving implementation of CAPAs and continuous improvement through change controls, and contributing to validation and regulatory deliverables. These responsibilities will be exercised through the scope of supporting technology transfers, clinical manufacturing, site readiness, process validation/PPQ, commercial manufacture readiness, and product lifecycle management activities. 
 

The ideal candidate brings hands-on experience with cell therapy unit operations through previous experience in process development and/or manufacturing, as well as expertise in technology transfer. Experience with process validation and commercialization activities is desired. This position will report to Director, MS&T, Cell Therapy Development and Operations. 

Key Responsibilities 

Site manufacturing support 

• Process Execution Support: Provide day-to-day technical support for cell therapy manufacturing, including on-the-floor support for critical campaigns (including occasional off-shift support where required) 

• Operations Support: Represent Site MS&T function at site operational tier meetings, providing collaborative inputs that drive site activities 

• Data trending and analysis: Maintain manufacturing data tracking system and control charts, perform trend analyses, identify signals, and drive timely signal-to-action with clear documentation and cross-functional alignment. 

• Process performance monitoring: Conduct batch record review, deviation assessment, and data trending to ensure robustness of cell therapy manufacturing processes. 

• Deviation/CAPA Support: Lead or co-lead technical investigations for deviations and process excursions, perform root cause analysis, develop and implement CAPAs with appropriate data. 

• Continuous improvements: Identify, justify, and implement continuous improvements by shepherding changes through cross‑functional change controls with appropriate risk assessments and comparability. 

• Raw materials: Support qualification of critical materials (e.g., cytokines, viral vector, single-use assemblies) and assess impact of raw material changes, and contribute to second-source strategies 

• Automation: Partner with automation/digital manufacturing teams to implement electronic batch record improvements 

• Documentation & GMP Compliance: Author and revise batch records, SOPs, and technical reports; protocols, summary reports, ensure adherence to cGMP/ATMP requirements and data integrity principles (ALCOA+). 

• Training & Knowledge Transfer: Deliver operator training on critical process steps or process changes; contribute to lessons-learned, playbooks, and best practices across sites. 

• Regulatory Contributions: Draft and review CMC sections (Module 3) response to agency question, support health authority and internal audits/inspections. 

Technology Transfer & Process Validation 

• Draft and review risk assessments and comparability study design 

• Contribute to technology transfer packages (process descriptions, URS inputs, BOMs, risk assessments), implement process changes, coordinate execution of engineering runs and comparability/bridging studies, author technical reports 

• Translate process characterization outputs from development into manufacturing controls, and draft sections of PPQ protocols/reports 

• Provide on‑the‑floor technical support during scale‑up, engineering runs, PPQ batches, and commercial manufacturing campaigns (including off‑shift support when required). 

Cross‑Functional Collaboration 

• Position serves as primary interface between site Manufacturing, site Quality, site Supply Chain, and global functions of Process Development and CMC regulatory 

• Support lifecycle management for cell therapy processes, including continuous improvement initiatives and post-approval changes  

Minimum Required Qualifications 

Education 

PhD in Chemical Engineering, Biochemical Engineering, Biotechnology, or related field with 1+ years of industry experience; OR M.S. with 5+ years of hands‑on industry experience, OR B.S. with 8+ years of hands‑on industry experience. 

Technical Skills 

• Strong technical and hands-on expertise in key cell therapy unit operations and common cell therapy processing equipment 

• Demonstrated experience working in GMP environments, including batch record execution or review, deviations, and investigations. 

• Proficiency with statistical analysis (including univariate, multi-variate analysis, control charts)  

• Demonstrated ability in accurate and thorough technical writing, paired with clear and concise verbal communication  

• Strong data analysis, and problem‑solving skills. 

Soft skills 

• Excellent cross‑functional communication and collaboration. 

• Ability to translate complex data into clear decisions and regulatory-ready narratives. 

• Excellent problem solving, cross-functional leadership, and communication under time-sensitive conditions. 

Preferred Qualifications 

• Experience with late‑stage clinical manufacturing support of cell therapy products 

• Experience with process validation and commercial readiness of cell therapy products 

Work Environment 

• On-site in Tarzana, CA 

• Ability to travel ~15% to other manufacturing facilities  

• On-call rotation during engineering/PPQ/critical campaigns
