Job Description

Xaira is hiring an AI Scientist for biomedical multimodal modelling to build foundation models that learn from both images and high-dimensional molecular (omics) data, treating them as two views of the same biological system. The goal is models that encode rich representations and can generate or infer missing parts of the data from partial observations.

At a glance

  • Team: Biomedical foundation models
  • Location: South San Francisco, California
  • Pay: $170,000 – $240,000 a year, as listed
  • Apply: open until filled (re-checked 14 October 2026)

What you would do

  • Develop multimodal foundation models spanning image and molecular data
  • Unify representation learning and generative modelling
  • Train large models on structured, high-dimensional datasets
  • Explore cross-modal alignment, prediction and generation, and build scalable data, training and evaluation systems

Why this role matters

Biology produces many kinds of data about the same cells, from microscope images to gene-expression profiles, and models that connect them could reveal how diseases work and which targets to drug. Building such foundation models is one of the most active frontiers of AI for science, and Xaira combines it with its own large-scale experiments, so models can be checked against fresh data rather than only public benchmarks.

What Xaira Therapeutics is looking for

  • Research experience with representation learning or generative models
  • Experience training large models on high-dimensional data
  • Comfort with evolving, research-driven problems

Nice to have

  • Experience with microscopy images, single-cell or other omics data

Pay and location

Xaira lists $170,000 to $240,000 a year for this role.

How to prepare for this application

  • Multimodal experience: show models that combined two or more data types.
  • Generative plus representation: the team wants both.
  • Scale: training on large, high-dimensional data is central.
  • Biology data: any omics or imaging work helps.
