Molecular and cell Biology: Leverage molecular and cell biology knowledge and experience to characterize cell models including primary and iPSC-derived cell systems for the development of imaging methods.

Screening and mechanistic studies: Execute routine screens and mechanism-of-action studies using high-content imaging and/or flow cytometry as well as molecular approaches to support programs across target validation, small-molecule identification and optimization, and clinical candidate selection.

Data analysis and reporting: Independently analyze assay data, including applying advanced image-analysis methods to develop and optimize analysis algorithms; perform quality control, process screening data, and communicate results clearly.

Project engagement: Actively engage in project discussions, contribute to decision-making, monitor project progress, and identify biology and pharmacology needs. Collaborative study design: Partner with project team members and DBP colleagues to design and execute studies that address project needs, interpret data to answer key questions, and help guide project direction when needed.

Leadership: Mentor other scientists to drive team success. Qualifications Must Have Education: PhD in Molecular Biology, Pharmacology, Cell Biology, or a related discipline with 1 to 3 years' experience in cellular assay development Technical expertise: Hands-on experience with high-content imaging and flow cytometry instrumentation, with familiarity in advanced image-analysis methods and software.

Cell models and characterization: Hands- on experience with physiologically relevant cell models (primary cells, iPSC-derived models). Familiarity with cell characterization methods and gene delivery systems. Scientific foundation: Broad and applied knowledge of cellular and molecular biology, with the ability to connect biological questions to appropriate assay strategies.

Learning agility: Demonstrated ability to acquire relevant disease area biology knowledge efficiently and apply this to a broad range of target classes. Problem solving: Strong willingness and ability to troubleshoot, solve problems, and overcome technical or scientific challenges.

Collaboration: Strong interpersonal and collaboration skills, with the ability to work efficiently and productively in team-based settings. Communication: Demonstration of excellent verbal and written communication skills. Nice to Have Experience across therapeutic areas such as Internal Medicine, Immunology & Inflammation, or Oncology.

Exposure to functional genomics approaches, including RNA-seq and CRISPR-based methods. Programming or computational biology experience to support algorithm development and data analysis.
