Build and scale advanced conversational AI products for healthcare, from ideation to reality.
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 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.
Requirements
- 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).

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.
