## Job description

## About Prosper AI

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 40 — 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.

## What you'll do

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 adapt instantly to messy, high-stakes healthcare conversations. On top of that, we are creating a layer of products that go beyond voice and meet patients where they are at (SMS, web, etc.). As a Product Engineer, you’ll be at the center of designing and building those products, taking them from ideation to reality.

This is a full-time role in Barcelona office with the possibility to move to the New York office.

## What we're looking for

- 5+ years of experience building products end-to-end, from putting together quick MVPs to deploying production-grade software and tracking its success.
- A strong understanding of the technologies that power our stack or their equivalents in other languages: FastAPI (Python) + PostgreSQL backend with a React (TypeScript) frontend.
- Experience managing large scale distributed systems with asynchronous workload orchestration.
- You have a passion for good product, and whilst not being a PM or designer you enjoy sketching UI in Figma and chatting with customers to learn about their pains.
- Founder mindset: ownership + hard work. You see Prosper as a learning step for your future startup.
- Be ready to handle the challenges of serving thousands of high stakes daily interactions with patients.
- Bachelor’s or Master’s degree in Computer Science, Engineering, Maths, Physics or related field (or equivalent experience).

Interviewing Process

1. Initial conversation to understand who you are, what you want to do, and where you wanna go (30 minutes)
2. Work on a take-home challenge to discuss in the following interview
3. Review your solution with a couple of engineers from the team (60 minutes)
4. Talk with the co-founder (60 minutes)
5. Offer stage

- Mission or purpose statement: "Unlock universal access to care by helping healthcare organizations achieve unprecedented efficiency with AI agents" and "wipe out $200B in admin waste, freeing healthcare to focus on what it does best—healing, not holding."

## Products & Services
- **AI Voice Agents for Patient Access**: Handles scheduling, rescheduling, cancellations, new patient intake, and insurance information collection in a single, natural conversation. Available 24/7 across all providers and locations.
- **AI Voice Agents for Payor Calls**: Automates benefits verification, eligibility checks, claims status inquiries, and prior authorizations by calling payers directly, navigating IVR trees, waiting on hold, and speaking with live representatives.
- **AI Voice Agents for Patient Billing**: Handles balance and statement questions, takes payments via phone, SMS, or email (PCI-compliant), and posts payments to the EHR automatically.

- **Deep EHR integration**: 80+ out-of-the-box integrations with read/write capabilities — "built into your practice, not bolted onto it."
- **Payor call capability**: When APIs fail, Prosper AI agents call the payer directly, navigating IVR and speaking with live reps — a critical moat in healthcare RCM.
- **Enterprise readiness**: HIPAA compliant, SOC 2 Type II compliant, 99.99% uptime, on-premise or cloud deployment, dedicated AI Strategist for onboarding.
- **Founding team pedigree**: Founders from MIT and Harvard with operational experience in healthcare call centers and insurance.
