- B2B SaaS to lead the rebuild of their design function. Highlights Barcelona (Hybrid: at least 2 days in office, Poblenou) AI tooling to experiment with, Urban Sports Club membership, Playflow salary benefits and many more. What is haddock? haddock is the market leader solution for point of control in restaurants, handling all back-office vital operations like product management, inventories, purchases, price tracking, document conciliation, bank conciliation, paychecks, clocking in/out, P&L reports, etc. Not only we have a system of record that helps operate restaurants with control and clarity, but we're also the leaders in offering AI Agents, starting with Fina. They work 24/7 doing the heavy, tedious work that our customers don't have time to do well. This is no AI hype. Our customers obtain visible value from our AI Agents, both in money and time saved. We're becoming strategic partners in the design of their businesses. Our mission is to empower millions of restaurateurs to level up their business. Our vision is to lead the market through innovation, strong relationships and by becoming the go-to tech partner for restaurant success. haddock is backed by Y Combinator, the accelerator behind Airbnb and Twitch. We're growing fast with support from top-tier investors like JME, Decelera, Extension Fund, Wayra, and Zone2Boost. Bonus: we're a step away from the people using what we build. Many of our restaurants are based right here in Barcelona, and they love haddock. Ready to lead design at haddock? We're rebuilding the design function at haddock, and looking for the senior designer to lead that from the front. This is a real opportunity to shape how design works here, the standards it holds, and the systems it runs on, with a lot of room to make it yours. If you're excited by that kind of ownership — and by embracing iteration, excellence, and AI like you've likely never done before — keep reading. What we're looking for We are looking for an action-oriented, curious, autonomous, and take full ownership of their work designer. You are champion of figuring out the unknowns. You talk to customers, deliver quality work, improve our tooling, and are ambitious. We strongly adhere to Lean Startup and Agile principles, favoring action over analysis, imperfect iteration over perfect delivery, face-to-face communication, and a fast-paced environment. We work in small mission-oriented squads of 1 to 3 people. 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 consistency, from scratch Our processes and tools are constantly improving, and everyone contributes to making them better. Some example high-level objectives you could work toward in your first months:
* Redesigning key flows so business data tells the story of the restaurant to their owners, surfacing financial metrics and insights clearly.
* Designing the experience for Fina, our AI Agent, so conversational and automated workflows feel trustworthy and effortless for non-technical restaurateurs.
* Increasing adoption of inventories to 50% of customers, by simplifying a crucial part of daily restaurant operations. If you're excited by ownership, autonomy, and designing technology that directly impacts real businesses every day, this is the right moment to join. Come on board while we're still a startup. It's much more fun and motivating than joining an already established scale-up or corporation, where your role is very defined and limited. This is more than a job. It's a chance to leave your mark on an industry that's ripe for transformation, and to shape what design becomes at haddock as we invest in it seriously. Our best perk is our work environment and the opportunities you'll get to learn and grow at haddock. 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 h
