Join to apply for the Product Engineer (Full Stack) role at haddock (YC W22)

haddock is the first Point of Control (POC) SaaS platform built for restaurants in Europe. We help restaurateurs run their entire operation from one place, with more control, clarity, and efficiency.

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.

Ever stayed in an Airbnb? 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 .

Why are we hiring?

We’re growing consistently and bringing in new revenue every month.

Now, we’re expanding the Product team to build faster, better, and smarter, and to bring in your ideas to shape the future of haddock.

About the role

Engineers at haddock are action-oriented , curious , autonomous , and take full ownership of their work.

Each of us leads initiatives, planning and executing independently, while collaborating with the tech lead and peers to refine solutions.

As a Product Engineer, you'll work across the stack — frontend, backend, infrastructure, monitoring, and integrations — to deliver outcomes that bring real value to restaurateurs.

Everyone has different strengths and preferences, and we aim to align projects with what you love doing most .

We’re always improving our processes and tools, and everyone contributes to making them better. We also share the “keep the lights on” work like monitoring and dependency management.

We’re a small team (~4 full-stack engineers + 1 AI engineer), and now is a great time to join : you’ll take ownership, make a real impact, and help define our future.

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, and several AI LLM integrations.

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 SaaS platform.
• 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.

What You Bring

You’re a capable engineer who can own features from idea to production and who thrives in a collaborative, fast-paced environment.

Experience : At least 3 years of professional software engineering experience, ideally working on web-based SaaS applications.

Technical expertise :

Fluency in Spanish and 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 ️

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.
