Job description

San Francisco, CA · On-site · Full-time Compensation: $170,000–$250,000 + 0.5%–1.5% equity

About the Company

Our client automates patient recruitment for clinical trials using AI agents that coordinate across SMS, voice, and email. Clinical-trial delays cost $600K–$8M per day in a $600B+ market, and the platform helps research sites close that gap. It's already working with 7 of the top 15 research-site networks in the country, battle-tested across 500K+ patient interactions, 190+ sites, and 300+ trials, and is well-backed by a top-tier venture firm and strategic healthcare investors.

Founded 2019 · 1–10 people (Seed) · Industry: Healthcare AI

The Role

A Founding Engineer reporting directly to the CTO, owning full-stack product development as the company scales its core platform and AI-agent capabilities. High-ownership work in a fast-paced, high-intensity environment with no playbook.

Tech stack: TypeScript, Python, AWS, Next.js.

Requirements

  • A recently active, green GitHub
  • A top-school pedigree (e.g., MIT, Stanford, Berkeley, CMU, Princeton, Harvard)
  • Can articulate technical depth in conversation
Why Join
  • Founding-engineer scope: report directly to the CTO, own full-stack product development, and help define architecture and shipping cadence as the team grows beyond its current four engineers
  • Backing and traction: well-backed, already deployed across 500K+ patient interactions with 7 of the top 15 research-site networks
  • Equity upside: 0.5%–1.5% at the founding stage, with real ownership from day one
  • Momentum: on track for a Series A in the next 4–5 months on current revenue trajectory
