Full Job Description

📋 Description

• At Labhouse, AI isn't just what we ship to users — it's how we operate internally. As our AI Engineer, you'll design and build the LLM-powered tools, agents, and automations that remove friction across every team: product, marketing, finance, people ops, and support.
• This is a hands-on, high-ownership role. You will:
• Identify manual, repetitive, or slow processes across teams and turn them into AI-powered tools and automations
• Design and build LLM-based agents that can reason, use tools, and complete multi-step tasks autonomously
• Own projects end-to-end — from scoping the problem and understanding the business need, to designing, building, and shipping the solution
• Integrate LLMs and agents with our internal systems and third-party tools (Slack, Ashby, BigQuery, and others)
• Work directly with team leads to understand where AI can unlock the most impact — and translate that into working products
• Measure the productivity and efficiency gains your work generates, and iterate based on real usage
• We care more about what you've built than where you studied. A degree in Computer Science, Engineering, or a related technical field is a plus, but relevant hands-on experience matters more than the diploma.
• You've already done this before — you've walked into a company, spotted where AI could solve a real problem, and built the solution yourself, end to end. You're not looking for your first shot at this.
• Strong, proven experience working with LLMs in production — prompting, fine-tuning, RAG, or agent-based systems
• Deep knowledge of agent frameworks and how to design multi-step, tool-using workflows
• Track record of shipping internal tools or automations that measurably improved productivity in a company
• Strong Python skills and comfort integrating APIs, webhooks, and third-party tools
• Business vision — you understand how a company operates and can spot high-leverage opportunities for automation without being told where to look
• Ability to work autonomously, prioritize based on impact, and ship without waiting for perfect conditions

🏖️ Benefits

• Competitive compensation package
• Hybrid work model based in Barcelona
• High ownership from day one — you define the direction, not just execute on it
• Work directly with the founders and a senior, low-ego team
• Real, immediate impact — your tools will be used by every team, every day
