Job Specifications

Based in San Francisco, we're an early-stage startup using advanced AI agents to meaningfully speed up clinical research. Our technology engages directly with patients — guiding them through qualification, enrollment, and long-term participation — helping research teams eliminate enormous operational waste and address one of the biggest chokepoints in drug development.

After bootstrapping our way to several major enterprise wins, we closed a multi-million dollar seed round backed by well-known investors. We’re now assembling a small, exceptional engineering team to take the platform to the next level.

What We’ve Already Built

Our AI agents currently manage 100K+ patient interactions each month, including:

Guiding people to appropriate studies based on clinical criteria
Collecting and verifying required study information on an ongoing basis
Offering round-the-clock support to reduce participant drop-off
Continuously adapting based on real-world trial outcomes

We spent months working inside research sites to understand the day-to-day reality of the problem, and that groundwork has helped us expand quickly across the clinical research ecosystem.

What We’ve Accomplished (Pre-Funding)

Rapid month-over-month growth, including multiple six-figure contracts
Largest active agreement exceeds $600K annually
Over a 90% success rate in commercial evaluations — we’ve never been displaced by a competitor
Multiple pilots underway with top-tier pharmaceutical organizations
Pipeline grows consistently via word-of-mouth from current partners

What You’ll Be Building

Systems that coordinate a large network of AI agents across hundreds of concurrent studies
Machine learning models that match patients to trials based on real clinical outcomes
Multi-channel communication layers (voice, SMS, email) powered by LLMs
Integrations with older healthcare systems that lack modern APIs

Who You Are

We’re looking for founding engineers who want to own massive parts of the product, thrive in high-velocity environments, and are excited to help reinvent how clinical research operates.

If you want to make a measurable impact on how quickly breakthrough therapies reach patients — while working at a company with real traction and a massive mission — we’d love to connect.
