Full Stack Software Engineer (Founding Team)

Arul Health
Email

Full-time, in person in Boston, MA (5 days a week).

About Arul Health

Arul Health is a care navigation platform for patients with serious illness. Our AI agents and human peer navigators do the healthcare logistics for patients and families: appointment scheduling, prior authorizations, insurance navigation, transportation, and financial assistance. We are an early-stage startup based at Harvard Business School, and Moderna CEO Stephane Bancel is one of our backers.

The role

You will be one of the first engineers at Arul Health. We welcome candidates at all experience levels, from new graduates to experienced engineers. You will build our patient-facing product and the AI agents that do work for patients. You will own features from start to finish, and you will help make decisions about our architecture and engineering culture.

What you will do

  • Build and operate AI agents that make calls, send messages, fill in forms, and complete multi-step healthcare tasks for patients.
  • Build agent orchestration: planning, execution, confidence scoring, escalation to human navigators, memory, and observability.
  • Build full stack features with Python (FastAPI) on the backend and React on the frontend.
  • Build and run services on Google Cloud (Cloud Run, Pub/Sub, Cloud SQL, Firebase, Vertex AI / Gemini).
  • Build tools for our human care navigators so that agents and humans can work together.
  • Ship fast, talk to patients and navigators, and make the product better each week.
  • Keep patient data safe and follow healthcare privacy rules (HIPAA).

What we look for

  • Experience building full stack software (Python and React or similar), from internships, past jobs, or your own projects.
  • Experience with LLMs and AI agents (for example LangGraph, tool calling, prompt design, evaluations) is a strong plus.
  • Experience with cloud infrastructure, APIs, and databases.
  • Ownership: you can take an unclear problem and ship a working solution.
  • You want to work in person with a small team in Boston.
  • You care about patients and want to make healthcare easier for people who are sick.

Why join

  • Do meaningful work that helps patients and families during serious illness.
  • Founding-team role with large ownership and impact.
  • Work closely with the founder and a small, fast team.
  • Health, dental, and vision benefits.
