A successful candidate has a strong background in Operations Research or Engineering and has experience in pharmaceutical CMC development or supply chain.
Key Responsibilities
Model Development & Decision Support
- Design, build, validate, and deliver forecasting, optimization, simulation, and decision-support solutions for complex scientific, planning, and operational problems.
- Develop long- and short-term portfolio, workload, resource, and capacity forecasts; quantify uncertainty, dependencies, and scenario sensitivities.
- Develop business operations analytics and laboratory or process digital twins that connect demand, workflow, equipment, capacity, and performance to actionable decisions.
- Apply operations research methods to clinical supply and development planning, making assumptions, trade-offs, and model limitations explicit.
Technical Leadership & Sustainable Delivery
- Develop reusable modeling frameworks, reference implementations, and practical guidance for forecasting, mathematical optimization, simulation, decision analysis, and uncertainty quantification.
- Apply disciplined software and model-development practices, including modular code, version control, testing, documentation, reproducibility, peer review, sensitivity analysis, and monitoring.
- Partner with J&J Technology and DDSAI teams on data integration, deployment, observability, security, support, and lifecycle ownership; work with quality and compliance partners where regulated controls are required.

Collaboration & Adoption
- Work with TDS scientists, engineers, laboratory leaders, Clinical Supply Chain, business operations, Digital Operations & Strategy, and Finance to define decision needs and embed solutions into established workflows.
- Collaborate with DDSAI data product, ontology, AI/ML, and platform teams on shared definitions, reusable data products, methods, and components.
- Communicate recommendations, assumptions, uncertainty, and limitations clearly to technical and business stakeholders, including senior leaders; build adoption through evidence and effective decision framing.
- Contribute to the Operations Research and Decision Intelligence roadmap, technical forums, communities of practice, and evaluation of emerging methods or external solutions.
Qualifications
Required
- Ph.D. in Operations Research, Industrial Engineering, Applied Mathematics, Statistics, Computer Science, Engineering, or a related quantitative discipline with 8+ years of relevant experience; or a master’s degree with 10+ years of relevant experience.
