Job Description

We're looking for a Lead AI Product Engineer to drive Fever's company-wide operational transformation. This is a powerful 50% leadership, 50% hands-on building role designed for someone who sits right at the intersection of human operations and advanced AI engineering.

Job Responsibility

  • Stakeholder Management & Discovery (50%): Partner with internal business leaders to audit their current manual processes
  • Hands-on Engineering & Architecture (50%): Design, code, and deploy advanced AI systems (LLM applications, agentic workflows, RAG, and custom chatbots) that solve those operational pain points and scale seamlessly
  • Lead & Mentor: Build and lead a small, agile team of AI engineers
  • Own the Product Lifecycle: Take internal tools from early discovery and rapid prototyping to production-grade deployment

Requirements

  • Proven AI Product Delivery: Deep, hands-on experience shipping AI systems in production (LLM frameworks like LangGraph, LlamaIndex, or agentic automation)
  • Strong Operational Sense: You can naturally look at a messy, manual process and instantly visualize how an AI product could streamline it to save hours of manual labor
  • Solid Engineering Foundations: Strong software engineering background (APIs, microservices, databases, AWS ecosystem)
  • Empathy & Communication: Exceptional ability to build relationships with non-technical stakeholders, navigate ambiguity, and align engineering efforts with operational needs
  • The 50/50 Split: You love writing clean, scalable Python code and building AI systems, but you are equally energized by talking to people, understanding their daily operational frustrations, and solving their problems

What we offer

  • Responsibility from day one and professional and personal growth in one of the most exciting AI roles in the company
  • Opportunity to have a real impact in a high-growth global category leader
  • A compensation package consisting of base salary and the potential to earn a significant bonus for top performance
  • Stock options plan
  • 40% discount on all Fever events and experiences
  • Based in Madrid, with a home office friendly setup
  • Health insurance and other benefits such as Flexible remuneration with a 100% tax exemption through Cobee
  • English / Spanish lessons
  • Wellhub membership
  • Possibility to receive in advance part of your salary by Payflow
