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.
