The job, in the employer's words
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 understanding, control strategy, risk assessment, and phase-appropriate decisions.
- Develop fit-for-purpose analytics: Build analytics for drug product unit operations such as blending, granulation, compression, coating, and fill/finish, as well as packaging and labeling operations, including yield, throughput, readiness, and supply-chain scenario analysis.
- Build reusable data products: Develop and maintain pipelines and FAIR data products that integrate internal and CRO/CDMO data into traceable, reusable datasets within Databricks and related platforms. Develop dashboards and visualizations that make process performance, campaign comparisons, and technology-transfer readiness clear to technical and executive audiences.
- Apply AI and own the digital roadmap: Serve as digital product owner for process modeling and technology-transfer analytics, defining priorities, driving adoption, and applying AI/ML—including agentic workflows and LLM-based tools—to accelerate CMC data review, knowledge capture, and routine analytical work with appropriate validation and data-integrity controls.
- Drive impact and enable teams: Use forecasting, scenario analysis, and cost-benefit analysis to improve right-first-time execution and shorten technology-transfer timelines. Present recommendations to stakeholders, contribute to CMC data science strategy and regulatory filings, and mentor colleagues in data science and modeling practices.
Qualifications and Key Success Factors
- Master’s degree in Chemical Engineering, Pharmaceutical Sciences, Data Science, or a related scientific or engineering field, with demonstrated application of data science to process development; Bachelor’s degree with equivalent experience will be considered.
- 5+ years of relevant experience in biotech/pharma process development, process engineering, or data science, ideally supporting drug substance and/or drug product development or technology transfer.
- Experience with process modeling, DoE, statistical analysis, and data-driven decision-making; exposure to packaging and labeling operations is a plus.
- Strong hands-on skills in Python and SQL, with experience using Databricks or comparable data platforms and BI/visualization tools such as Power BI, Tableau, or Spotfire.
- Experience developing AI/ML applications and integrating AI-enabled tools into scientific or business workflows preferred.
- Working knowledge of cGMP, ALCOA+, CMC regulatory expectations, and GxP-validated computerized systems; experience supporting regulatory filings is a plus.
- Experience working with CDMOs/CROs, external data flows, Agile ways of working, digital product ownership, or change management preferred.
- Demonstrated ability to solve ambiguous problems, communicate complex ideas clearly, work with self-direction, and build trusted relationships across functions.
- Brings intellectual curiosity, creativity, innovation, organization, attention to detail, and a strong bias toward high-quality results. Thrives in an agile, entrepreneurial environment and is willing to both teach and learn.
