The agentic drug company. We simulate human biology. Backed by Y Combinator.
About the role
We are hiring a Founding Research Scientist to own the modeling in our biology programs end to end. This is the role that turns a partner's scientific question into a model task, a dataset, an evaluation, and a result a pharma team will act on. You will work directly with the founders on the projects that define the company over the next year, and you will have a lot of room to decide how we model biology, not just implement someone else's plan.
What they're looking for
- Own modeling for one or more live pharma and biotech programs: framing the problem, choosing the representation and architecture, building the training and evaluation loop, and delivering results to the partner
- Train, fine-tune, and post-train biological foundation models on single-cell, perturbation, spatial, multi-omic, imaging, and clinical assay data
- Build models of cellular state and response: perturbation prediction, in-silico screening, cross-species and cell-line-to-patient translation, deconvolution, and related virtual-cell tasks
- Design evaluations that biologists trust: held-out perturbations, unseen cell types and tissues, cross-species and cross-cohort generalization, and wet-lab-in-the-loop validation with our partners
- Decide what data to acquire or generate next, and shape the data-generation experiments we run with academic and pharma collaborators
- Turn one-off project results into reusable model capabilities and product workflows
More about this role
CellType is building foundation models and agent systems for biology.
We train models to reason over cells, tissues, and patients: predicting how a perturbation, a drug, or a disease state changes biology, and how findings in cell lines and animals translate to humans. We work with pharma, biotech, and diagnostics partners on live problems such as preclinical-to-clinical translation, cross-species toxicology, perturbation and response prediction, cell-type deconvolution from clinical assays, and spatial biology.
We are building the core intelligence layer for biology.

We care about two things in equal measure: you have trained models at scale before, and you understand biology well enough to know when a result is meaningful versus an...
