Job Description

We're looking for a Lead AI Engineer to drive Fever's company-wide AI 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. We are not looking for a theoretical manager who focus on KPIs, nor a developer who only wants to code in isolation. We need a hybrid leader. Half of your time will be spent interacting with stakeholders across business domains (Operations, Creative, Support), shadowing them to understand their manual workflows, and identifying where AI can genuinely give them their time back. The other half will be spent in the trenches: designing the technical architecture, writing production code, and building internal AI products—like advanced chatbots, agents, and automated workflows—alongside a small, high-performance squad.

Job Responsibility

  • Partner with internal business leaders to audit their current manual processes
  • Act as a translator: understand their operational bottlenecks, manage expectations on what AI can do, and shape those needs into a clear AI product features
  • Design, code, and deploy advanced AI systems (LLM applications, agentic workflows, RAG, and custom chatbots) that solve those operational pain points and scale seamlessly
  • Build and lead a small, agile team of AI engineers
  • Lead by example by contributing to the codebase
  • Take internal tools from early discovery and rapid prototyping to production-grade deployment, ensuring they are intuitive enough for non-technical teams to adopt

Requirements

  • You love writing clean, scalable Python code and building AI systems, but you are equally energized by talking to people
  • Deep, hands-on experience shipping AI systems in production (LLM frameworks like LangGraph, LlamaIndex, or agentic automation) — ideally tools or chatbots that have actively optimized human workflows
  • 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
  • Strong software engineering background (APIs, microservices, databases, AWS ecosystem) combined with a pragmatic, outcome-driven mindset
  • Exceptional ability to build relationships with non-technical stakeholders, navigate ambiguity, and align engineering efforts with operational needs

What we offer

  • Responsibility from day one and professional and personal growth
  • 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
  • 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
