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 integrate seamlessly with our customer's complex internal tools. As a Forward Deployed Engineer you’ll be working side by side with our AI PMs, looking for technical opportunities to increase the performance of our agents for each of our clients.

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

What we're looking for

• 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).
