Senior Machine Learning Engineer

Senior Machine Learning Researcher – Biological Foundation Models

Location : Boston, MA (onsite, full-time)

Compensation : $250k+ base salary - RSUs

About the Company

A well-funded, venture-backed biotech / AI company is building foundation-scale models for biology to enable breakthroughs in cell therapy and precision medicine. The team combines leaders from AI research and computational biology, creating a unique environment at the intersection of cutting-edge machine learning and transformative healthcare applications.

The Role

We are seeking a Senior Machine Learning Researcher to develop large-scale models for single-cell and multi-omics data. You will design transformer-based architectures, explore diffusion and generative approaches, and help build the technical platform that powers next-generation therapies. This is an opportunity to apply state-of-the-art ML to some of the most complex data in science — with direct impact on future clinical applications.

Responsibilities

• Build and optimize foundation-scale models for single-cell and high-dimensional biological datasets
• Collaborate with biologists to ensure outputs are interpretable and biologically meaningful
• Explore novel architectures (transformers, diffusion, multimodal models) for biological representation learning
• Develop scalable, distributed pipelines for trillion-token-scale training
• Provide technical leadership and mentorship to other ML researchers
