Core Responsibilities

Primary Functions

Lead design-of-experiments (DoE) for formulation optimization and process parameter screening; analyze multivariate data to define robust operating spaces and recommend control strategies for scale-up and manufacturing transfer.
Develop, qualify and validate analytical assays (HPLC, UPLC, GC, MS, UV, dissolution, potency assays) and interpret results to support stability, release, and characterization studies in accordance with GLP/GMP standards.
Formulate new products (small molecules, biologics, peptides, vaccines, or advanced materials) by selecting excipients, optimizing concentrations and assessing critical quality attributes (CQAs) to achieve target performance and stability.
Translate bench-scale processes to pilot and commercial scale, designing scale-up strategies, defining scale-dependent parameters, and collaborating closely with process engineering and manufacturing teams to ensure reproducibility.
Prepare and maintain thorough technical documentation including study protocols, batch records, technical reports, validation/qualification documents, and regulatory CMC submissions (e.g., IND, IMPD, DMF) to support approvals.
Execute stability study programs (accelerated, long-term, ICH conditions), interpret degradation pathways, propose formulation or packaging changes, and present shelf-life recommendations based on empirical data and predictive models.
Design and run in vitro and in vivo assays to evaluate product performance, efficacy, and safety when required; analyze bioassay data and integrate results with product development decisions.
Implement and maintain laboratory best practices including risk assessments, change controls, CAPA, and deviation investigations to ensure quality, traceability, and regulatory compliance across development activities.
Lead cross-functional project teams (R&D, QA, regulatory, manufacturing, supply chain) to drive product development milestones, manage project timelines, and present technical updates to stakeholders and project management offices.
Troubleshoot process and analytical issues using root cause analysis tools (5 Whys, Fishbone, FMEA), design corrective actions, and verify effectiveness through targeted experiments and data review.
Establish and optimize purification, separation, and downstream processing steps (chromatography, filtration, centrifugation) for biologics or complex molecules to achieve required purity and yield targets.
Evaluate raw material suppliers and excipient compatibility; design incoming material testing strategies and define supplier quality agreements to mitigate supply chain risks for CMC-critical components.
Develop and execute scale-up studies in pilot plants and tech-transfer workshops, write manufacturing transfer packages, and provide on-site support during initial commercial batches to ensure successful knowledge transfer.
Drive formulation screening campaigns using high-throughput techniques and automation where applicable; curate experimental libraries and use informatics to accelerate candidate selection.
Validate process analytical technology (PAT) and in-line monitoring methods to enable real-time quality control, continuous manufacturing, and increased process understanding.
Create predictive stability and degradation models using kinetic and statistical approaches; generate risk-based shelf-life estimates and justify packaging decisions to regulatory authorities.
Maintain awareness of current scientific literature, competitive products, and emerging technologies; evaluate and recommend adoption of new methods, instrumentation, or platforms to improve development efficiency.
Mentor junior scientists and technicians, provide hands-on training in experimental techniques, instrumentation, and data analysis, and contribute to building a high-performing R&D team culture.
Ensure laboratory safety and environmental compliance by enforcing SOPs, hazard assessments, and appropriate disposal protocols for hazardous and biological materials.
Support intellectual property creation by documenting novel processes and formulations, collaborating with legal teams to prepare invention disclosures and patent filings.
Coordinate and oversee external contract research organizations (CROs) and contract manufacturing organizations (CMOs) for outsourced studies and pilot production, ensuring data integrity and delivery to project timelines.
Develop cost-of-goods (COGS) analyses, identify process efficiencies and yield improvements to optimize commercial viability and scalability of product candidates.
Facilitate technology transfer packages with clear batch records, critical process parameters (CPPs) and acceptance criteria to enable reproducible manufacturing across multiple sites.
Present technical data and development narratives to regulatory agencies, cross-functional leadership, and commercial teams; prepare technical sections for regulatory filings and respond to agency questions.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist procurement and supply chain with technical specifications for raw materials and packaging components.
Participate in hazard and risk assessments for new processes or equipment installations.
Provide scientific input to marketing and product launch teams to ensure technical accuracy of promotional materials.
Support cost modeling and vendor evaluations for new analytical instruments or pilot-scale equipment.
