Senior Data Scientist

Location: This position may be performed remotely, but requires the flexibility and willingness to travel as needed.

The Opportunity

Praxis is seeking a Senior Data Scientist to build and deploy the models, data products, and digital tools that help us develop drug substance and drug product processes, as well as the packaging and labeling that gets them to patients quickly and correctly the first time.

Working within CMC alongside Engineering, Process Chemistry, Formulation, Analytical Development, Quality, Data Science, and external CDMOs, you will turn process and experimental data into actionable insight and phase-appropriate decisions across small molecule and oligonucleotide programs.

This is a hands-on, high-ownership role for a data scientist or process engineer who thrives on open-ended problems. You will combine process knowledge with modern data science and AI to improve technology transfer timelines, strengthen process understanding, and make CMC data FAIR, traceable, and reusable across the organization.

Primary Responsibilities

• Build and deploy models: Lead the development, validation, and deployment of mechanistic, hybrid, and data-driven models supporting drug substance, drug product, packaging, and labeling processes, technology transfer, and manufacturing. • Turn CMC data into decisions — Partner with technical teams and CDMOs to translate DoE, PAT, IPC, batch record, and other process data into predictive models and analytics that inform process…
