As a scientific developer and trusted scientific computational methods and cheminformatics expert, you will establish AI testing and evaluations strategies and drive the development of high performant, AI-enabled scientific workflows. This is a highly collaborative position at the intersection of computational sciences, research teams, and Digital Technology & Engineering.

This is a Boston based, hybrid position requiring 3 days/week onsite.

Key Duties and Responsibilities

• Translate scientific requirements into agentic AI solutions that can autonomously reason, plan, and execute complex tasks
• Build, test, and deploy AI-enabled solutions that support drug discovery across small molecule and protein therapeutics
• Collaborate with computational scientists, software engineers, and cross-functional project teams to deliver scalable AI solutions
• Apply software engineering, DevOps, and compliance best practices to deliver production-grade AI systems
• Design and implement testing, evaluation, and validation strategies for agentic AI systems
• Contribute to innovation efforts that help research programs realize value from Agentic AI and Generative AI technologies.
• Stay current with emerging agentic AI patterns and prototype new capabilities to evaluate their scientific impact.

Knowledge and Skills

• Deep understanding of drug discovery, with the ability to bridge the gap between scientific requirements and production-ready AI solutions
• Expert knowledge of small molecule scientific computational methods and cheminformatics
• Working knowledge of building AI agents including tools, orchestration and multi-step reasoning
• Strong experience with scientific software development; well versed in CI/CD and DevOps practices
• Strong Python skills and solid machine learning/AI foundations - able to write clean, production-grade code with a firm grasp of system design principles
• Expertise in one or more of the following areas: cheminformatics, machine learning, computational drug discovery, scientific data science
• Strong understanding of modern AI technologies, including large language models, agentic systems, retrieval-augmented workflows, and AI-assisted scientific applications
• Excellent communication skills, collaboration, and stakeholder-management skills; can explain technical trade-offs to non-technical stakeholders.

Education and Experience

• Ph.D. in Computational Chemistry, Cheminformatics, or a related scientific discipline
• More than 8 years of experience in scientific software development and application to drug discovery programs
• Hands-on experience developing, deploying, and managing AI-enabled scientific products, platforms, or applications
• Demonstrated success translating scientific opportunities into scalable computational, data science, software, or AI capabilities that deliver measurable scientific and business impact
• Significant experience working across discovery research, computational sciences, data science, and engineering organizations
• Experience applying AI, machine learning, or advanced computational methods to real-world drug discovery challenges
