Who you are
- ? 5+ years of product design experience in scaling B2B SaaS companies
- ? End-to-end product design experience: from discovery and research to interaction design, prototyping, and validation. We aren't looking for a "screen decorator" — we need someone responsible for outcomes, not just for delivering mockups
- ? Strong command of design systems, including experience building or scaling one as a product grows
- ? Active, hands-on use of AI in your design process — not just familiarity, but developed judgment (criterio) for when and how to use it, and real productivity gains to show for it
- ? Fluent in Spanish and comfortable in English. We tend to speak Spanish at the office and in Slack, and write documentation and projects in English
- ⭐️ You'll stand out if you've already designed for AI-driven products in production — at haddock we already have 15+ AI workflows live, and that number keeps growing
- Experience growing or leading a design function at an early-stage startup
- Familiarity with front-end concepts (components, states)



— enough to have real conversations with engineers about feasibility
- Experience running customer interviews or usability tests end-to-end, not just observing them
What the job involves
- As the senior designer leading this next chapter, you'll set the bar for how design gets done at haddock. You'll own the end-to-end process across the whole product, not just a corner of it
- Own the end-to-end design process, from discovery to shipped feature
- Design flows and interfaces for both our system of record and our AI Agents, like Fina
- Talk to customers to validate ideas, run usability tests and gather feedback
- Turn ambiguous problems into clear, usable, and elegant solutions
- Work closely with engineers during implementation to protect the quality of the final result
- Track usage, measure interactions and extract conclusions to inform new iterations
- Build haddock's design system and set the standard for brand consist
