The Role

We are seeking an AI Research Scientist to join our world-class AI Research team. You will build the core intelligence behind Dawn and Phoenix, our continuous, always-on care agents. This is a unique opportunity to operate at the frontier of both research and product development simultaneously, pushing the boundaries of what's possible in clinical AI.

What You'll Work On

Healthcare demands AI that goes far beyond answering questions or completing tasks. It requires systems capable of sustained engagement across dozens of interactions, understanding patient history, perceiving present state, and guiding recovery over weeks and months. Your work will focus on:

Memory Systems: Building advanced memory architectures for long-term patient engagement and context retention
Multimodal Perception: Integrating video, audio, and wearable signals into unified clinical AI models
Multi-Turn Reinforcement Learning: Developing algorithms for long-horizon treatment planning and autonomous clinical decision-making
Autonomous Care Delivery: Creating AI that provides real clinical care at scale, without human intervention

Who You Are

You thrive at the frontier of uncertainty and are comfortable making high-stakes decisions with incomplete information. You are motivated by outsized impact and excited by the opportunity to pioneer something genuinely new. You bring both scientific rigor and product-minded thinking—understanding that research impact is measured by peer-reviewed publications AND patients treated.

Our researchers don't choose between scientific excellence and clinical impact. The team actively publishes in top-tier AI conferences and clinical journals while shipping models that power care for hundreds of thousands of patients. You will have access to world-class compute resources, proprietary clinical datasets, and a collaborative team of world-leading researchers.

Why Join Us

This is high-pressure, high-reward work. You'll operate where research and product development intersect—often without a playbook. If you're energized by building AI that delivers real clinical value at unprecedented scale, this is the opportunity for you.
