# AI Engineer - Agents

Labhouse is a Barcelona-based startup studio building AI-powered mobile apps used by hundreds of thousands of people worldwide. Our products, including Invoice Fly and Summary AI, are designed to make everyday tasks faster, smarter, and simpler through a subscription model that puts the user first. We were founded by Andrés Bou and Horacio Martos, the duo behind SocialPoint (acquired by Take-Two Interactive), and we operate with the mindset of a product company: small teams, high ownership, and a relentless focus on building things that matter. Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below. About the Role: We’re bringing AI Agents into Summary AI and Invoice Fly, and you’ll be the one building them from scratch. This isn’t a role where you join an existing system and pick up tickets. You’ll own the whole cycle: decide what to build, design the architecture, implement it, measure how it performs with real users, and keep iterating until it works. These won’t be thin wrappers around an LLM. You will build multi-agent systems that do real work for millions of users,
