Qualifications

• PhD in ML, computational biology, bioinformatics or related field with substantial AI/ML experience.
• Deep learning research on biological data with depth in single-cell omics, biological sequences, or cellular imaging.
• Strong Python and PyTorch skills including model implementation, training, fine-tuning, debugging, and GPU inference.
• Experience with representation/self-supervised learning on biological foundation models.
• Experience building reproducible ML pipelines with version control, tested environments, and data management.
• Strong statistical and model-evaluation skills with proper baselines, validation design, batch effects, confounding, and uncertainty assessment.
• Ability to own research projects and collaborate with experimental/computational colleagues.
• Clear written and verbal communication of methods and implications to diverse audiences.
• Publications or accessible code showing research or software contributions.

Responsibilities

• Develop biological foundation models and predictive methods for target identification and prioritization, disease biology, and mechanism-of-action studies.
• Partner with experimental scientists to define questions and test model predictions.
• Define project objectives, milestones, and success criteria aligning model performance with research decisions.
• Curate and harmonize biological datasets, address metadata quality and reproducible processing.
• Develop reusable workflows for model training and inference and promote adoption by research teams.
• Research model architectures and self-supervised methods for single-cell, omics, and imaging data, including multimodal approaches.
• Train, fine-tune, and debug models in PyTorch on GPU/HPC, balancing performance and cost.
• Explore generative/agentic AI workflows for hypothesis generation, data interpretation, and experiments planning.
• Benchmark against baselines using independent datasets and meaningful endpoints; assess leakage, generalization, uncertainty, and interpretability.
• Communicate findings and limitations to scientists, technical peers, and leadership.
• Mentor colleagues and maintain reproducible experiments and responsible data/model use.
• Contribute to publications, IP, and internal knowledge sharing; evaluate emerging methods for BioAI priorities.
