AI Engineer, Haddock

• Bachelor’s degree or equivalent experience in Mathematics, Data Science, Computer Science, Machine Learning, or a related field
• Hands-on experience with Large Language Models (LLMs) or generative AI systems in real-world use cases
• You’re truly AI-native: you’re passionate about working at the frontier of AI, you actively follow new papers, models, and techniques, and you continuously refine how you use them in practice
• You’re also AI-native in how you build software: you’re up to date with modern AI-powered dev tools (e.g. Claude Code, Cursor, Codex or similar), and you assemble your own agents and workflows to move faster as an engineer
• You combine engineering rigor with product thinking: you don’t just write code, you design, debug, and improve end-to-end systems that solve real problems
• Fluency in Spanish and comfort in English. We tend to speak Spanish at the office and in Slack, and write documentation and projects in English
• We’re building something ambitious, and we’re looking for someone ready to grow with us, take real ownership, and shape the company's future

• They talk to customers, deliver quality work, improve our internal tooling, and are ambitious. We look for people with these same motivations and ways of working
• We strongly adhere to the Lean Startup and Agile principles, favoring action over analysis, imperfect iteration over perfect delivery, face-to-face communication, and a fast-paced environment
• Your focus and ownership will be to help haddock grow as fast as possible. No distractions, your mission is to make every part of the company as AI automated as possible
• You’ll have full freedom to experiment, time and resources to stay at the cutting edge of AI, and the support of a strong AI, tech and product team around you

• Collaborate closely with leadership to identify and fully automate high-leverage operational loops
• Think ahead: Architect scalable solutions as we grow fast

• We move fast and communicate openly. Our goal is to wrap up the process within a week. Here's what to expect:
• Intro call with Enric (AI Lead), 25 mins
• Call with Pol (co-founder, CPO), 25 mins
• Technical interviews with Enric and Guillermo(Head of Tech) (2 hours)
• Sounds like an opportunity? Apply now. We’d love to meet you
