➡️ Why are we hiring?
We're looking for one more engineer with passion for crafting products, delivering value, and pushing the bar on what being impactful looks like
We think you will unlock many opportunities to work on more ambitious goals. So we can't wait to have an extra team member :)
➡️ About the role
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.
➡️ What You’ll Do
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.
➡️ What You Need To Bring

👉 Experience: At least 5 years of professional software engineering experience, ideally working on web-based SaaS applications.
👉 Technical expertise:
Proficiency in TypeScript, React and Node.
Experience using databases and working with cloud infrastructure
Experience in environments using Microservices or some flavor of service oriented architecture.
Experience defining, implementing and shipping initiatives. End to end.
👉 AI Experience
You've been developing with AI over the past year.
You have developed good judgement (criterio) on using it with good results, and you don't delegate basic understanding to the AI.
👉 Critical thinking: The ability to evaluate an idea, break down the problem, and identify an Agile way of achieving the objective.
👉 Fluency in Spanish and comfortable in English We tend to speak in Spanish at the office and in Slack, and write documentation and projects in English.
➡️ You’ll Stand Out If You Bring ⚡️
Experience working at a SaaS fast-paced startup
Familiarity with the HORECA (hospitality and restaurant) sector.
➡️ Why Join Us?
We’re building something ambitious, and we’re looking for someone ready to grow with us, take real ownership, and shape the product’s future.
This is more than a job. It’s a chance to leave your mark on an industry that’s ripe for transformation.
➡️ What we offer?
💸 A competitive salary (€40–55k gross/year).
🏢 A bright modern office in Barcelona, in Poblenou. Probably the best office you've ever worked at.

haddock is a software that helps restaurateurs to have better cost control in their businesses. Thanks to AI, the platform needs a photo of the invoice or delivery note to digitize all their information. Not only is this data displayed on a dashboard, but also is used to notify of price variations, create dynamic bills of materials, which are updated with the latest purchase price of their products, and detect errors between invoices and delivery notes. Moreover, their POS can be connected to the platform so that restaurateurs can have their margin always updated and, ultimately, have a global vision of their business in an all-in-one platform.
