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. You talk to customers, deliver quality work, improve our tooling, and are ambitious.

We started as a system of record (inventories, purchases, invoices, bank reconciliation, P&L; reports) and turned it into the harness where our AI workforce lives. 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.

Many of our restaurants are based right here in Barcelona, and they love haddock. First and foremost, the project itself: a growing startup with ambition, product-market fit, and great culture. A bright, modern office in Barcelona, in Poblenou.

Probably the best office you've ever worked at (PS: The attached photo was taken on the office rooftop during a product retro breakfast with the team). Hybrid work, with 2 days at the office to build trust, collaborate, align, and get creative. Portfolio review and design deep-dive with the Product team, 45–60 mins.
