- Develop, optimize, and troubleshoot purification methods to improve purity, yield, recovery, throughput, robustness, and solvent efficiency.

- Scale up chromatographic purification processes from analytical and laboratory-scale systems to pilot, kilo-lab, and plant-scale operations.

- Drive technology transfer of purification processes from R&D; to manufacturing, ensuring technical readiness, documentation quality, and process reproducibility.

- Support process validation batches at plant scale, including execution readiness, deviation investigation, data review, and technical troubleshooting.

- Provide scientific guidance for impurity isolation, characterization support, fraction strategy, column selection, loading optimization, gradient design, buffer selection, and purification workflow improvement.

- Collaborate with process chemistry, analytical development, quality assurance, manufacturing, engineering, regulatory, and project management teams to ensure successful project delivery.

- Ensure compliance with GMP, safety, data integrity, documentation, and applicable regulatory expectations.

- Establish best practices, standard operating procedures, training modules, and technical standards for preparative purification operations.

- Mentor, coach,



and manage a team of approximately 1015 scientists, chemists, and technical staff, ensuring capability building, productivity, and high-quality execution.

Required Qualifications and Experience

- Masters degree or Ph.D. in Chemistry, Pharmaceutical Sciences, Chemical Engineering, Analytical Chemistry, Organic Chemistry, or a related discipline.

- Minimum 20 years of relevant experience in preparative HPLC purification, process development, scale-up, and manufacturing support.

- Extensive experience with purification of peptides, GalNAcs, ADC-related molecules, linkers, oligonucleotides, small molecules, and impurities.

- Strong understanding of reverse-phase chromatography, ion-pair chromatography, normal-phase chromatography, chiral separations, ion-exchange approaches, and related preparative purification techniques.

- Hands-on experience with preparative HPLC systems, columns, detectors, fraction collectors, solvent systems, and chromatography data systems.

- Proven experience in transferring purification technologies from laboratory development to plant-scale manufacturing.

- Demonstrated experience supporting process validation, GMP campaigns, technical investigations, and manufacturing troubleshooting.

- Strong knowledge of process robustness, column loading studies, impurity purge strategy, recovery optimization, and purification economics.





- Experience leading multidisciplinary technical teams and managing 10–15 team members in a development or manufacturing support environment.

Technical Competencies

- Preparative HPLC method development, optimization, troubleshooting, and scale-up.

- Purification strategy design for complex synthetic and bioconjugated molecules.

- Technology transfer, process validation support, and GMP manufacturing readiness.

- Impurity isolation, fraction pooling strategy, solvent selection, and recovery improvement.

- Column chemistry selection, lifecycle management, cleaning strategy, and system suitability evaluation.

- Preparation and review of technical reports, batch records, validation protocols, deviation responses, and regulatory-support documents.

Leadership Expectations

- Build and lead a high-performing purification team with clear accountability, technical depth, and robust execution discipline.

- Prioritize project work, allocate resources, review technical risks, and ensure timely delivery of purification milestones.

- Develop junior and mid-level scientists through coaching, technical review, and structured training.

- Promote a culture of safety, compliance, scientific rigor, collaboration, and continuous improvement.

- Represent purification function in cross-functional project meetings, technology transfer discussions, manufacturing readiness reviews, and process validation forums.

Preferred Attributes

- Strong problem-solving ability for difficult separations, low recovery, poor resolution, high solvent consumption, and scale-up challenges.

- Ability to balance scientific quality, plant feasibility, timelines, cost, and regulatory expectations.

- Excellent communication, technical writing, stakeholder management, and decision-making skills.

- Experience working with global teams, external partners, contract manufacturing organizations, or customer-facing technical programs is desirable.
