Engineer advanced conversational AI agents for healthcare, focusing on real-time performance and integration with client tools.

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 a Forward Deployed Engineer, you'll work side by side with our AI PMs to find technical opportunities that increase the performance of our agents for each of our clients.
  • Day to day, you'll:
  • Build features that ship fast — develop new capabilities, MVPs, and internal tooling across our FastAPI (Python) + PostgreSQL backend and React (TypeScript) frontend, with a bias toward getting things in front of clients quickly.
  • Integrate with messy real-world systems — build and maintain integrations with EHRs and payor systems (and the APIs, edge cases, and quirks that come with them) so agents fit seamlessly into each client's stack.
  • Debug live, high-volume systems — diagnose and resolve issues for agents making thousands of daily phone calls, where reliability and call quality directly affect patient and provider experience.
  • Turn client feedback into product — close the loop with AI PMs and engineering, surfacing patterns across clients and feeding them back into the core platform.
  • Tune and optimize voice agents — iterate on LLM prompting, voice and transcription configuration, and conversation logic to make agents sound more human and perform reliably under real-time latency constraints.
  • Manage multiple clients at once — prioritize across competing deadlines while keeping quality high.

Requirements

  • Experience with software development, ideally through an internship or side project.
  • A good understanding of the technologies that power our stack or their equivalents in other languages: FastAPI (Python) + PostgreSQL backend with a React (TypeScript) frontend.
  • Experience working closely with clients and finding creative solutions to their needs is a plus.
  • Familiarity with LLMs, AI agents or other ML models is a plus.
  • Founder mindset: ownership + hard work. You see Prosper as a learning step for your future startup.
  • Be 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).

Conditions

  • The opportunity to work alongside an experienced team that has built and scaled a fast-growing, Series A company backed by top Silicon Valley investors
  • Work on innovative products that are transforming US healthcare operations and sit at the heart of conversational agents.
  • Significant growth opportunities as the company scales and the team takes on increasing ownership
  • Competitive compensation
  • Join an international team based in the heart of Barcelona
  • Have real ownership and impact from day one
  • Be part of a culture that rewards bold thinking, analytical rigor, and tangible results

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 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.
