Director of Pharmaceutical Sciences

What You’ll Do

• Lead formulation and pharmaceutical sciences activities across multiple programs, ensuring high-quality, timely data generation
• Set experimental direction across preformulation and formulation (solubility, salt forms, dissolution, stability, physicochemical characterization)
• Operate as a hands-on scientific leader across experimental design, data interpretation, and troubleshooting
• Build and develop a team of ~3–5 scientists and research associates
• Translate program goals into structured experimental plans with clear milestones and decision criteria
• Generate data packages that inform feasibility, development decisions, and partner discussions
• Partner with Data Science to incorporate AI and computational tools into workflows
• Enable external partners to apply the Solusalt platform through clear, reproducible approaches while protecting proprietary know-how
• Serve as a technical lead in partner interactions, including feasibility discussions and development planning
• Collaborate cross-functionally with analytical, process development, manufacturing, regulatory, and quality teams
• Oversee CRO/CDMO workstreams to ensure quality and execution
• Establish efficient lab operations, workflows, and data standards

What You Bring

• PhD in Pharmaceutics, Pharmaceutical Sciences, Chemistry, Chemical Engineering, or related field
• 10–15+ years in pharmaceutical sciences or small molecule drug development
• Proven experience leading lab-based teams and driving scientific execution
• Strong foundation in formulation and preformulation (solubility, salt forms, dissolution, stability)
• Ability to design experiments and translate data into clear development decisions
• Experience advancing early-stage work into reproducible, development-ready approaches
• Track record of effective cross-functional and external collaboration
• Comfort working in data-driven environments and alongside data science teams
• Nice to have: Experience with solubility-enabling approaches, familiarity with reformulation or 505(b)(2) strategies, experience with platform technologies in partner-facing environments, exposure to early CMC, scale-up, or process robustness, experience incorporating AI/ML approaches in R&D, experience managing CRO/CDMO relationships, background in a startup or emerging biotech environment
