Job Description
OBJECTIVE:
Synthetic Molecule Process Development (SMPD) is responsible for developing robust, cost-effective processes for new small-molecule pharmaceuticals, including methods to achieve and control high standards of crystal form, particle size distribution (PSD), and product quality. The Senior Staff Engineer - Crystallization & Particle Engineering (Modeling) will join a dynamic and innovative team of engineers and scientists within SMPD's Process Engineering & Technology Group.
The successful candidate will have a strong background in crystallization process development and population balance modeling (PBM). They will lead and tackle challenging problems in particle engineering by leveraging expertise in crystallization kinetics, mass/heat transfer, mathematical modeling, and crystallization design. Additionally, the Senior Staff Engineer will establish scale-up and scale-down models for crystallization operations, using both first-principle and data-driven approaches.
The role includes the application of process analytical technologies (PAT) combined with mathematical models (both statistical and first principle) to enhance process understanding. This in turn will enable effective development, optimization, scale-up, and troubleshooting of crystallization processes using in-silico approaches.
ACCOUNTABILITIES:

• Leads and contributes to the design, development, optimization, and scale-up of crystallization processes for synthetic molecule drug substances, leveraging advanced modeling, simulation, and population balance modeling approaches.
• Develops, implements, and validates predictive crystallization models (mechanistic, data-based or hybrid) to predict and control particle size distribution, morphology, purity, and polymorphic form.
• Designs and executes experimental workflows, integrating in-line and off-line process analytical technologies (PAT), for data-rich model development and verification.
• Collaborates cross-functionally with Automation, Manufacturing, Process Engineering, and analytical experts to develop and deploy digital twins for crystallization and particle engineering processes.
• Drives adoption of an "in-silico first" approach, recommending, justifying, and implementing robust crystallization modeling tools and workflows across the organization.
• Provides expert technical leadership within the crystallization modeling domain, influencing strategic direction and independently resolving complex technical issues through predictive modeling.
• Reviews, interprets, and communicates modeling outcomes and experimental data to multidisciplinary teams and stakeholders to support informed decision-making and process improvements.
• Authors technical reports, validation documents, regulatory filings, and peer-reviewed manuscripts related to crystallization modeling and particle engineering methodologies.
• Maintains awareness of emerging trends and tools in crystallization modeling, proactively identifies relevant vendor solutions, and actively participates in academic and industry collaborations to advance modeling capabilities.
• Champions knowledge-sharing and democratization of crystallization modeling and simulation methodologies, providing training and guidance to support broader technical capability building across the department and global organization.

EDUCATION, EXPERIENCE AND SKILLS:
Education and Experience:
Required:

• Ph.D. or postdoctoral fellowship in Chemical Engineering or a related pharmaceutical science with 3+ years of relevant industry experience.
