The Drug Chemistry team operates within the Analytical Method and Stability Center (AMSC) in the Global Analytical Development Synthetics organization, a division of Therapeutics Development & Supply (TDS) at Johnson & Johnson Innovative Medicine. Within Analytical Development, we bring together expertise in chemistry, analytics, computational sciences, and digital innovation to advance the understanding of molecular stability, reactivity, and developability throughout the drug discovery and development lifecycle.

We are seeking a highly motivated Senior Scientist with a strong background in organic chemistry and a passion for scientific innovation. In this role, you will investigate the chemical behavior of drug candidates, design and execute studies that generate critical development insights, and help address complex pharmaceutical challenges. You will combine experimental and data-driven approaches to understand degradation pathways, reaction mechanisms, and factors that impact product quality and stability.

Working in a highly collaborative environment, you will partner with scientists across multiple disciplines, including analytical sciences, formulation, toxicology, and computational chemistry, to support the development of innovative medicines. You will contribute hands-on laboratory expertise while leveraging emerging technologies, predictive modeling, and digital tools to accelerate scientific understanding and decision-making.

Beyond project delivery, you will help shape the future of drug chemistry by contributing to scientific initiatives, exploring new technologies and methodologies, and sharing knowledge through internal and external collaborations. This role offers the opportunity to make a meaningful impact on both the development of medicines and the evolution of how pharmaceutical science is conducted.

Overall Qualifications

• PhD in Organic Chemistry, Analytical Chemistry, Pharmaceutical Sciences, or a related field.
• 2+ years of relevant industrial or postdoctoral experience.
• Experience in synthesis, degradation chemistry, and/or analytical characterization of complex molecules.
• Strong understanding of reaction mechanisms, impurity profiling, and pharmaceutical development.

Required Experience and Skills

• Proven ability to design, execute, and interpret scientific studies independently.
• Strong problem-solving, communication, and collaboration skills.
• Ability to work effectively in multidisciplinary teams and manage multiple priorities.
• Interest in applying analytical, computational, and data-driven approaches to solve drug development challenges.
• Experience with, or willingness to learn, advanced characterization techniques and emerging technologies.
• Knowledge of kinetic modeling, computational chemistry, AI, machine learning, or predictive modeling is a plus.

What You Will Bring

• Curiosity and passion for understanding molecular behavior.
• A collaborative mindset and strong experimental skills.
• A drive to translate scientific insights into practical solutions that advance pharmaceutical development.
• The ability to communicate complex scientific concepts to diverse audiences.
