KEY RESPONSIBILITIESDigital Twin Development & Decision Intelligence• Design, build, validate, and maintain digital twins and decision models of TDS/DPDS operations to support portfolio planning, capacity and resource allocation, demand/supply planning, scenario analysis, and operational decision-making.
• Apply data science, operations research, forecasting, simulation, uncertainty quantification, mathematical optimization, heuristics, and machine learning methods to solve high-value business and scientific planning problems.
• Translate complex development, manufacturing, clinical supply, and planning processes into fit-for-purpose computational models that capture uncertainty, constraints, and cross-functional interdependencies.
Technical Delivery & Software Development Discipline- Develop robust, reusable analytical workflows and modeling assets using Python and modern data science tooling, including cloud-based services.
- Apply software engineering best practices, including version control, modular code design, testing, documentation, reproducibility, and code review.
- Use modern development environments, including AI-assisted coding tools where appropriate, to accelerate delivery while maintaining quality, transparency, and maintainability.
Cross-Functional Leadership, Mentorship & Business Impact- Partner with scientific, technical, operations, finance, and digital stakeholders to define requirements, shape analytical solutions, and embed outputs into business planning and decision workflows.
- Lead technical work across multiple concurrent projects while remaining a hands-on contributor.
- Communicate model assumptions, limitations, results, and recommendations clearly to technical and non-technical audiences.
- Mentor junior colleagues and provide technical guidance to consultants, post-doctoral researchers, and external collaborators contributing to project delivery.
QUALIFICATIONSRequired- Advanced degree in Operations Research, Industrial Engineering, Applied Mathematics, Statistics, Computer Science, Data Science, Chemical Engineering, Chemistry, Physics, or a related quantitative field.
- 3-5+ years of relevant experience applying data science, operations research, simulation, forecasting, optimization, or scientific computing methods to complex R&D, manufacturing, clinical supply, technical operations, or business planning problems.
- Strong Python programming skills and demonstrated use of modern analytical development practices, including version control, testing, documentation, reproducibility, and code review.
- Proven track record of delivering analytical products, computational models, or decision intelligence tools that influenced business, scientific, or operational decisions.
- Demonstrated ability to provide technical leadership in cross-functional environments while remaining a hands-on individual contributor.
Preferred• Ph.D. in Operations Research, Engineering, Applied Mathematics, Computer Science, Statistics, Data Science, or a related quantitative discipline.
• Experience in pharmaceutical product development, CMC, technical development, manufacturing, clinical supply, supply chain, portfolio planning, capacity planning, resource planning, or regulated life sciences environments.
• Experience deploying simulation, forecasting, optimization, or AI/ML-enabled decision tools into business workflows at enterprise scale.
• Exposure to developing and/or deploying agent-based AI solutions
Why This Role Is UniqueThis is a rare opportunity to grow in one of the world's most ambitious and fast-growing R&D Data Science organizations, shaping how advanced modeling, simulation, and optimization transform decision-making across Drug Product Development & Supply, with direct impact on Therapeutics Development & Supply. Your work will directly improve how Johnson & Johnson plans and executes its development portfolio, allocates critical resources, and accelerates delivery of next-generation therapies to patients globally.
