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.

What You'll Do

• 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

What We're Looking For

• 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

Preferred Background

• EEG, computational neuroscience, or biosignal modeling
• Distributed training with PyTorch, DeepSpeed, 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.
