Lead and build real-time AI systems for conversational healthcare agents, guiding a team and shipping complex integrations.
Responsibilities
- At Prosper, we're pushing the limits of what's possible with real-time AI. We're not just making voice agents that "talk" — we're engineering systems that sound human, reason under strong latency constraints, and integrate seamlessly with our customers' complex internal tools. 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.
- This is a player-coach role: roughly half your time is IC work on the hardest client and platform problems, and half is leading the people, process, and technical standards of the FDE area.
- Day to day, you'll:
- 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.
- Set the technical direction for the FDE area — define the architecture, patterns, and best practices for how we deploy, integrate, and optimize agents across clients, and make sure the team builds reusable solutions instead of one-off fixes.
- Own the FDE process — establish how the team scopes client work, prioritizes across competing deadlines, handles on-call and incidents, and feeds learnings back into the core product.
- 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.
- Be the technical face for key clients — partner directly with our most important healthcare customers from onboarding through optimization, translating their workflows into agent behavior that works in production.
- 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.
- Partner with PMs and Engineering leadership — work closely with AI PMs and the core engineering team to align the FDE roadmap with product strategy and surface patterns across clients.
Requirements
- Strong software engineering background, with experience leading projects or teams (formal management experience is a plus, but we care more about demonstrated technical leadership).
- Solid understanding of the technologies that power our stack or their equivalents: FastAPI (Python) + PostgreSQL backend with a React (TypeScript) frontend.
- Experience working closely with clients and finding creative solutions to their needs.
- Familiarity with LLMs, AI agents, or other ML models.
- Comfortable balancing hands-on IC work with people management and process ownership — you're energized by both.
- Founder mindset: ownership + hard work. You're excited to build and lead a function from an early stage.
- Ready to handle the challenges of supporting AI voice agents making thousands of daily phone calls.
- Bachelor's or Master's degree in Computer Science, Engineering, Maths, Physics, or related field (or equivalent experience).
Other
- 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.
