• 👉 Technical expertise:
• Proficiency in TypeScript, React and Node

• Experience in environments using Microservices or some flavor of service oriented architecture
• Experience defining, implementing and shipping initiatives. End to end

Desirable

• Engineers at haddock are action-oriented, curious, autonomous, and take full ownership of their work
• They are champions of figuring out the unknowns. They talk to customers, deliver quality work, improve our internal tooling, and are ambitious. We look for people with these same motivations and ways of working
• We strongly adhere to the Lean Startup and Agile principles, favoring action over analysis, imperfect iteration over perfect delivery, face-to-face communication, and a fast-paced environment
• Each of us leads initiatives, planning and executing in small mission-oriented squads of 2 or 3 people
• As a Product Engineer, you'll work across the stack (frontend, backend, and infrastructure) to deliver outcomes that bring real value to restaurateurs. Between frontend and backend, our time right now is likely spent 50% backend, 20% AI workflows, 20% frontend and 10% infra. We need you to be good at backend and to enjoy it as much as we do!
• Everyone has different strengths and preferences, and we aim to align projects with what you love doing most
• Our processes and tools are constantly improving, and everyone contributes to making them better
• Keep-the-lights-on work is shared, like bug fixing, monitoring and dependency management. We succeed at this by having a rotating squad of Defenders that tackles this kind of maintenance work
• Bonus: You’ll be just a step away from the people using what you build. Many of our restaurants are based right here in Barcelona, and they love haddock
• ➡️ Our Tech Stack
• TypeScript, React, React Router, Fastify, PostgreSQL, MongoDB, Google Cloud Platform, Langfuse, PostHog and several AI integrations
• We heavily use AI workflows and agents for our development, but also to empower the entire organization to be 10x productive. What a time to be alive!
• We have an architecture that kind of looks like microservices, with one main service that is more monolith than microservice. Most of our stack is serverless though, and we can rapidly upgrade and evolve our infra
• As part of our product team, you’ll build and ship features that make a real difference in restaurants' day-to-day operations:
• 👉 Build product: Design, build, and maintain our full-stack platform and AI Agents
• 👉 Solve challenges: Focus on outcomes, not obstacles
• 👉 Think ahead: Architect scalable solutions as we grow fast
• 👉 Improve process: Help us move from scrappy to smart
• 👉 Mentor others: Share your knowledge and shape the culture
• Some example objectives that you could work towards in your first months are:
• Enabling Fina to handle even more administrative work for our customers
• Making it effortless for our customers to make purchase orders to their suppliers directly from haddock
• Automating operational work in restaurants via developing AI Agents that work on our Point of Control
• Help our customers understand the health of their business directly in haddock, via reports, dashboards, data aggregations and insights
• Streamline internal operations at haddock by making Sales, CX, Finance and Product collaborate smoothly over shared AI-powered tools

• We move fast and communicate openly. Our goal is to wrap up the process within a week. Here's what to expect:
• 30-min intro call with Guillermo (Head of Technology)
• Technical interviews with Guillermo and another engineer (2 hours). Part 1: architectural solution thinking, and part 2: live coding changes on a React + Node app
• Executive interview with Pol (co-founder, CEO) and/or Ingrid (Head of Product)
• Sounds like an opportunity? Apply now. We’d love to meet you
• Important: applications without some kind of personalized message or cover letter will be discarded
