Key Duties And Responsibilities

• Provide scientific leadership and ownership of stem cell-derived cellular models, differentiation platforms, and assay systems as a direct line manager and/or matrix manager of a small team.
• Define experimental strategy, technical roadmaps, and decision criteria for complex differentiation and characterization challenges.
• Distill complex, multidimensional datasets into clear conclusions and actionable recommendations that inform program-level decisions.
• Lead development of robust, quantitative experimental platforms by integrating stem cell biology, assay development, imaging, and computational analysis approaches.
• Drive advanced troubleshooting and methods development to overcome biological and technical challenges associated with stem cell differentiation and functional assessment.
• Serve as a scientific point of accountability in cross-functional discussions, providing clear, data-driven guidance to program leadership and stakeholders.
• Contribute as a scientific lead to invention disclosures, patent filings, publications, and internal technical documentation.
• Provide scientific mentorship and technical direction to junior scientists and research associates.

Knowledge And Skills

• Deep expertise in pluripotent stem cell culture and directed differentiation of stem cells.
• Strong proficiency with functional, molecular, and imaging-based assays relevant to stem cell differentiation and cellular characterization.
• Demonstrated ability to integrate experimental biology with quantitative data analysis to support scientific decision-making.
• Experience using Python or similar scripting languages for data analysis, visualization, workflow automation, or management of large, multidimensional experimental datasets strongly preferred.
• Experience with high-throughput or automated cell culture and cell-based assay systems is a plus.
• Familiarity with Benchling or similar structured data and ELN/LIMS systems preferred.
• Excellent scientific communication skills, with the ability to clearly convey complex findings to technical and non-technical audiences.

Education And Experience

• Ph.D. (or equivalent degree) in molecular and cell biology, developmental biology, stem cell biology, or related disciplines and 4-7 years of relevant post-doctoral employment experience,
• Masters Degree (or equivalent degree) in molecular and cell biology, developmental biology, stem cell biology, or related disciplines and 7+ years of relevant employment experience,
• Bachelor's Degree (or equivalent degree) in molecular and cell biology, developmental biology, stem cell biology, or related disciplines and 10+ years of relevant employment experience.
