About the Role
We are seeking a Principal Medicinal Chemist to lead and advance small-molecule drug discovery programs from early hit identification through development candidate selection. This is a senior, hands-on scientific leadership role requiring deep expertise in medicinal chemistry, strategic thinking, and cross-functional collaboration.
This position calls for a highly creative and experienced chemist who can independently design and execute medicinal chemistry strategies while contributing to the integration of computational and AI-driven approaches into drug discovery workflows. The ideal candidate will combine strong technical depth with the ability to guide internal teams and external partners toward impactful outcomes.
Requirements
Must-Have
- PhD in Organic Chemistry or a related field with 3-8 years of industry experience (or MS with 5-10 years, BS with 8-15 years) in medicinal chemistry
- Proven track record of advancing drug discovery programs through key milestones (Hit-to-Lead and Lead Optimization)
- Deep expertise in synthetic organic chemistry, including modern methods and reaction mechanisms
- Strong experience in structure-based and ligand-based drug design
- Demonstrated ability to optimize compounds for potency, selectivity, and DMPK/safety properties
- High level of creativity, productivity, and independent problem-solving ability
- Experience managing external CROs and collaborating across disciplines
- Excellent English communication skills with the ability to clearly present complex scientific concepts
- Experience working remotely with international teams.
Nice-to-Have
- Experience integrating computational chemistry, machine learning, or AI-driven design into medicinal chemistry workflows
- Background in predictive toxicology or ADMET modeling
- Prior experience contributing to IND-enabling studies or clinical candidate selection
- Familiarity with modern data science tools and cheminformatics platforms.
Key Responsibilities
- Propose and independently drive medicinal chemistry strategies to progress programs from hit identification through lead optimization to development candidate selection
- Lead chemistry efforts within cross-functional project teams – computational scientists, biologists, and ML engineers
- Design novel compounds using structure-based and ligand-based approaches to optimize potency, selectivity, and drug-like properties
- Analyze SAR data and guide iterative design cycles to find a balance between potency, selectivity, and physico-chemical properties
- Contribute to and integrate AI-driven and computational modeling insights into compound design strategies
- Serve as a technical leader and mentor for internal chemists and external collaborators
- Manage external CRO partnerships to ensure high-quality and timely delivery of chemistry objectives
- Author and contribute to patent applications, scientific publications, and internal reports.
Values & Cultural Alignment
- Operates with ownership and urgency in ambiguous scientific environments
- Communicates complex modeling concepts with clarity and precision
- Thrives in cross-disciplinary collaboration between science and engineering
- Approaches scientific challenges with intellectual rigor and curiosity
- Balances research depth with practical execution toward milestone delivery
