Prosper is building the most advanced conversational AI agents for healthcare — human‑like phone agents that handle the administrative work draining the system: claims status checks, benefit verification, prior authorizations, patient scheduling, and balance reminders. Our mission is to eliminate $200B in administrative waste so healthcare professionals can focus more on healing and less on paperwork.
Headquartered in New York with an office in Barcelona, we work with dozens of large and enterprise healthcare organizations, and we've raised $35M from top investors including a16z, Base10, YC, and Emergence. We're a highly motivated team of 20 — ex‑MIT, HBS, Bain, and Math/CS/Physics olympiad medalists — and as we prepare for our next stage of growth, we're looking for ambitious, exceptionally talented people to help scale our product and grow with us.
As Lead Forward Deployed Engineer , you'll be both a hands‑on builder and the leader of our FDE function — setting the technical direction, shaping how the team works, and growing the engineers on it, while still shipping code yourself.




Lead and grow the FDE team — manage a group of Forward Deployed Engineers, owning their growth, performance, hiring, and day‑to‑day direction, and building a high‑trust, high‑ownership culture.
Stay hands‑on — personally take on the most ambitious or highest‑stakes work: complex integrations, performance bottlenecks, and live debugging of agents making thousands of daily phone calls.
Tune and optimize voice agents — guide the team's work on LLM prompting, voice and transcription configuration, and conversation logic to make agents sound human and perform reliably under real‑time latency constraints.
Strong software engineering background, with experience leading projects or teams (formal management experience is a plus, but we care more about demonstrated technical leadership).
FastAPI (Python) + PostgreSQL backend with a React (TypeScript) frontend.
