About Xaira

We’re pioneering the discovery and development of life-changing medicines through the transformative power of artificial intelligence. Backed by Lightspeed, NEA and Sequoia.

About the role

Build pipelines for preprocessing, normalization, and integration of large-scale single-cell and perturbation data.

What they're looking for

  • PhD or equivalent in Computational Biology, Computer Science, Bioinformatics, or related discipline
  • Strong expertise in single-cell data analysis, particularly perturb-seq
  • Hands-on experience with foundation models or large-scale self-supervised learning (e.g., transformers, variational autoencoders)
  • Strong coding skills in Python, ML frameworks (PyTorch/TensorFlow), and single-cell analysis tools (Scanpy, Seurat)
  • Experience in developing scalable ML methods for large biological datasets
More about this role

Xaira is an innovative biotech startup focused on leveraging AI to transform drug discovery and development. The company is leading the development of generative AI models to design protein and antibody therapeutics, enabling the creation of medicines against historically hard-to-drug molecular targets. It is also developing foundation models for biology and disease to enable better target elucidation and patient stratification. Collectively, these technologies aim to continually enable the identification of novel therapies and to improve success in drug development. Xaira is headquartered in the San Francisco Bay Area, Seattle, and London.

About the Role

We are looking for an AI Scientist to join our team at the intersection of machine learning and single-cell biology. This role will focus on developing and applying foundation models to large-scale perturb-seq and single-cell datasets to uncover new biological mechanisms and therapeutic opportunities. You will help design scalable ML architectures that can extract insight from high-dimensional perturbation data and integrate across multi-omic modalities.

  • Design, train, and refine foundation models tailored to perturb-seq and...
