Role overview

You will build the technical foundation for the autonomous healthcare clinic, developing AI-native tools that automate complex operational workflows. Working across TypeScript, Python, and Svelte, you’ll take ownership of entire domains to create agent-driven systems. This is a high-impact role where you’ll solve real-world inefficiencies in a rapidly scaling healthtech environment.

Healthcare Software

Synthax is a health-tech company, founded by a doctor and engineer, tackling healthcare’s billion-dollar productivity crisis.

Doctors spend 50% of their time on administrative tasks—our goal is to eliminate this. Synthax automates clinical documentation, extracts actionable tasks, and seamlessly integrates with existing workflows.

Our AI agents work alongside your current solutions, allowing clinicians to focus on what they do best: caring for patients.

What you will do

  • Design and implement end-to-end features using a modern stack including TypeScript, Python, Swift, and Svelte to automate clinic operations.
  • Harness the power of AI coding agents and LLMs to build autonomous systems for front-desk scheduling and clinical documentation.
  • Take full ownership of product domains, moving from problem definition to deployment while ensuring the right tool for the right job.

Who this is a fit for

  • An AI-native engineer who leverages coding agents effectively and understands how to build platforms that integrate LLM capabilities into real-world workflows.
  • A full-stack generalist with an ownership mindset, comfortable working across the stack and learning new technologies like Python or Swift as needed.
  • Ideally possesses background in healthtech or experience with healthcare data standards like FHIR/HL7, though a thirst for solving hard problems is the priority.

Why this role is remarkable

  • Founding-level impact at a Seed-stage company already powering 20 US healthcare clinics within just 18 months of launch.
  • Work at the intersection of AI and healthcare, building an “agent harness” that handles everything from prescription refills to remote patient monitoring.
  • Join a mission-driven team founded by a Doctor and an AI Engineer, offering a unique blend of deep clinical insight and technical excellence.
