Responsibilities

Build AI that directly shapes R&D decisions Design, develop, and scale production-grade AI systems embedded in drug discovery and development programs—where model outputs inform choices on molecules, experiments, trials, and patient access to clinical trials

Own foundational and predictive modeling end-to-end From molecular optimization and experimental design to clinical trial simulation, patient stratification, and operational forecasting—take ideas from concept through validation, deployment, and measurable value

Advance generative AI for drug design Apply state-of-the-art generative approaches to molecular and protein engineering. Prototype quickly, evaluate rigorously, and deploy responsibly in high-stakes scientific contexts

Engineer elegant, reliable ML systems Architect robust pipelines with modern MLOps: cloud and HPC environments, distributed training, reproducibility, governance, and observability—designed for scientific credibility and operational scale. Automate and standardize the entire lifecycle of ML systems, from initial development to long-term production maintenance, providing compliance and an audit trails

Decode high-dimensional biology Integrate multimodal data—omics, imaging, real-world evidence, and scientific literature—into representations that surface biological insight and guide experimental and clinical strategy

Influence portfolio and strategy decisions Partner with scientific and strategy leaders to model uncertainty, run scenario analyses, and optimize resource allocation across a complex R&D portfolio

Stay at the frontier Continuously assess emerging AI methods and tools, translating advances into practical, defensible applications for a specific R&D discipline

Raise AI fluency across the organization Mentor scientists and engineers, foster hands-on curiosity, and help build a culture where rigorous experimentation and learning are the norm

Represent the science externally Publish, present, and engage with the broader AI and life-sciences community at leading conferences and forums

Demonstrated expertise in predictive modeling, generative AI, and ML system design

Strong programming skills in Python and modern ML frameworks (e.g., PyTorch, TensorFlow), plus experience scaling models in cloud and/or HPC environments

Proven ability to collaborate with other scientists, and could include laboratory bench researchers, clinicians, product teams, and business leaders

Clear scientific communication, intellectual curiosity, and a mission-driven mindset focused on improving patient outcomes

Preferred

Experience in life sciences preferred, but not required (pharma, biotech, or health tech)

A working understanding of R&D workflows is preferred but not required, across target identification, lead optimization, translational science, clinical design, operations forecasting, or portfolio analytics
