We are reimagining drug discovery through the lens of agentic AI—turning scientific expertise into composable, intelligent workflows that accelerate every stage of the DMTA cycle. We are seeking a highly skilled and innovative Principal Scientist to help lead this transformation by developing agentic-AI capabilities and computational platforms for In Silico Discovery (ISD).

The successful candidate will design and help implement computational platforms that serve as the foundation for agentic workflows— bridging end-user scientists and platform engineering teams. They will help define how scientists interact with AI-driven tools, set best practices for agentic development, and upskill scientists across the department. This role collaborates closely with project and platform engineering teams to turn ISD's scientific tools into a trusted agentic AI discovery engine.

Key Responsibilities

• Serve as a key agentic-AI enablement leader for ISD: define best practices and help shape the department's agentic strategy.

• Expose computational science capabilities as agent-callable services and help build specialized domain agents, in partnership with platform engineering and portfolio teams.

• Lead design and development of scientific platforms and workflows—including virtual screening, active-learning triage, and ADMET-ML scoring—as reusable, agent-ready components for hit identification and compound optimization.

• Advance small molecule informatics across the DMTA cycle, guiding bench scientists in analysis and decision-making.

• Upskill ISD scientists in agentic-AI tools, prompt engineering, and AI-augmented research practices.

Required Qualifications

• PhD in Cheminformatics, Computational Chemistry, Chemical Engineering, or a related field.

• Minimum of 3 years of industry experience with a proven track record of delivering end-to-end solutions from conceptualization to implementation.

• Hands-on experience with LLM-based tools for scientific workflows (e.g., Claude Code), including skill/prompt engineering and MCP or RAG/knowledge-base integration.

• Deep expertise in cheminformatics software (e.g., KNIME, OpenEye, RDKit) and programming languages (e.g., Python, R), including familiarity with scientific computing and ML libraries (e.g., pandas, scikit-learn, PyTorch).

• Experience with SQL/Snowflake and modeling chemistry data (structures, assay and screening data). Comfort with cloud-native and containerized deployment environments.

• Experience working in cross-functional teams and translating ideas from bench scientists to informatics solutions, with excellent problem-solving and communication skills.
