Presentation
➡️ 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.
Responsibilities
- 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
Requirements
- 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.
- 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 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.
Nice to Have
- 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
We Offer
- Competitive salary (€40–60k gross/year) that will grow as haddock - and you - grow.
- A bright, modern office in Barcelona, in Poblenou.
- Hybrid work, with 2 days at the office to build trust, collaborate, align, and get creative.
- All the AI tooling you want to experiment with.
- A subsidized Urban Sports Club membership: yoga, HIIT, hot studios...
- Salary flexibility benefits through Playflow.
About the Company
haddock is the AI-powered back-office for restaurants. 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. They run 24/7, doing the heavy operational work so restaurateurs can focus on what they do best.
Our customers don't just save time. They make better decisions, catch problems before they escalate, and run tighter businesses. That's the kind of value we're here to deliver.
👉 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 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.
Our Hiring Process
We move fast and communicate openly. Our goal is to wrap up the process within a week. Here's what to expect:
- Intro call with Ingrid (Head of Product), 25 mins.
- Portfolio review and design deep-dive with the Product team, 45–60 mins.
- Design challenge or take-home exercise, followed by a walkthrough session.
