Head of Artificial Intelligence​/Principal AI Research Scientist

Head of AI / Principal AI Research Scientist

Location:

Boston or San Francisco

We are partnering with a well‑funded, venture‑backed neurotechnology company building one of the most ambitious AI platforms in the market today: a foundation model designed to learn directly from large‑scale, real‑world brain and behavioral data.

This is a rare opportunity to become the first senior AI leader and architect a next‑generation “world model” that treats neural activity as a high‑dimensional language, with applications spanning predictive health, cognitive computing, and human‑AI integration.

• Design and train a large‑scale foundation model from the ground up
• Build the end‑to‑end AI stack, including data pipelines, training infrastructure, and deployment systems
• Apply advanced techniques including Transformers, VQ‑VAE, self‑supervised learning, and world models
• Lead the technical roadmap and hire the AI research and engineering team
• Work closely with executive leadership and investors to define a category‑defining platform

• Proven experience building large models from scratch (not just fine‑tuning)
• Deep expertise in LLMs, generative modeling, sequence modeling, and representation learning
• Experience with world models, multimodal AI, or temporal systems
• Strong technical leadership and a track record of hiring and mentoring teams
• Credibility from top‑tier AI labs, research organizations, or recognized startups

• EEG, computational neuroscience, or biosignal modeling
• Distributed training with PyTorch, Deep Speed, or FSDP
• PhD in Computer Science, Machine Learning, Applied Mathematics, or related field

This role is ideal for someone who wants to build a transformational AI platform from first principles and establish a world‑class research organization.
