Big Picture Bio is a seed-stage techbio company, backed by DSV, building a computational drug discovery platform that constructs causal biological networks from two primary sources: structured extraction of published experimental literature and large-scale primary human single-cell omics data. Our multi-agent AI system reasons over these networks to generate, simulate, and rank mechanistic hypotheses for combination therapies — with system accuracy verified against top-tier researchers at the Allen Institute. We are initially focused on oncology. The Role (remote, timezone-restricted) You will design and build production bioinformatics pipelines for new modalities—spatial transcriptomics, single-cell proteomics, and spatial proteomics—extending our existing scRNA-seq infrastructure. These pipelines feed directly into an agentic hypothesis generation system: the quality of what goes in determines the quality of every therapeutic hypothesis that comes out. You’ll work closely with our Head of AI & Technology (Dr. Francesco Moramarco) and Head of Platform (Dr. Moustafa Khedr) to: - Build end-to-end pipelines (ingestion, QC, normalization, integration, annotation, differential analysis) - Design modality-specific statistics: spot deconvolution, spatial autocorrelation, ADT normalization, protein-RNA joint embedding, segmentation, spillover correction - Extend hierarchical cell type annotation across modalities - Codify best-practice workflows into reusable templates for agent execution - Sanity-check outputs to catch batch effects and artifacts before they propagate
