MUST HAVE: In-depth understanding and experience with developing novel multimodal LLM architectures and Reinforcement Learning. Available to work full-time and on-site 3 days a week.

At M31 Biomedical AI, we are redefining how artificial intelligence understands human health and biology. Our models power universal segmentation and imaging analysis across multiple medical modalities to uncover new biological and clinical insights.

We’re seeking a full time AI Scientist to support the development of multimodal biomedical foundation models incorporating SOTA LLM architectures, training frameworks (i.e. Reinforcement Learning, JEPA) and other methodologies. You’ll be working with a diverse team of AI researchers, clinicians, and computational biologists to explore how deep learning can advance personalized medicine and healthcare for patients.

This position is ideal for someone passionate about biomedical AI, multi-modal data, and collaborative, high-impact research.

What You’ll Do

Define research direction to incorporate SOTA multimodal LLM methodologies to foundational models for biomedical applications

Define data input, model outputs, labels and outcomes to develop clinically and biologically meaningful model objectives.

Design experiments to critically assess model performance

Contribute to publications in leading conferences and journals, and open source software that advance the field of biomedical AI

Build, review and maintain reproducible and modular codebases for training and running experiments with deep learning models

Collaborate with research partners to collect, preprocess,



and harmonize structured and unstructured clinical data, pathology and radiology images.

Work closely with data scientists and clinicians to ensure scientific and clinical relevance

Discover, validate and implement new AI tools to improve workflow efficiency

Document and maintain reproducible workflows using Git, Python, and cloud-based tools

Contribute to publications, internal reports, and presentations summarizing key findings

Create clear, compelling presentations and visualizations that translate highly technical results for both clinical and technical audiences

Why Join Us

Be part of a leading biomedical imaging AI company recognized for its foundational work in universal segmentation

Collaborate with top academic and hospital research teams on cutting-edge multi-modal AI projects

Gain exposure to large, high-quality datasets spanning medical imaging and clinical data

Work in a mission-driven workplace that bridges scientific research and real-world healthcare impact

Enjoy flexible work arrangements, mentorship, and opportunities for authorship and recognition

Required Skills & Background

Master’s or PhD (or equivalent experience) in Engineering, Computer Science, Mathematics, Biomedical Engineering, Computational Biology or a related field.
