Tech Lab

Product Owner
Mainloop is an engineering company in Barcelona . You get the interesting part of a new company, with a real customer and real products from day one.
What we build is the software that automates professional‑services work — across roughly fifteen countries, for businesses drowning in administration: the forms, the approvals, the reconciliations, the spreadsheet somebody rebuilds every month. Most automation teams stop at the demo. Here you are the product manager and the product owner: there is no one above you writing the strategy for your products, and no one below you writing the stories. In our team, coding agents build most of what ships, steered by your developer. Agents amplify whatever they are given: a sharp specification becomes working software astonishingly fast, and a vague one becomes a thousand lines of confidently wrong code. Writing them precisely is the highest‑leverage hour of your week.
Surveys now find most companies shipping faster with AI while almost none can point to the return. It is this job, and in an AI‑native team it is a more senior, more consequential job than the same title has ever been — because every decision you write down gets built, quickly, exactly as you wrote it.
Acceptance, in a world where software appears fast, is the quality bar. It is a fraction of what our deployed engineers do,



but it is not zero, and the POs who never leave the office are the ones whose products stop being used.
Flights, your first month's accommodation while you find somewhere of your own, the visa and paperwork costs, and an agent to handle the bureaucracy — the NIE, the TIE appointment, the apostilles — instead of leaving you to meet the administrative system alone. Spanish lessons if you want them — and in this seat they will pay for themselves.
A relocation bonus, paid on arrival rather than dripped out. Healthcare with no premium, no deductible and no network — from day one, and not tied to staying in this job.
Thirty calendar days of holiday — that is 22 working days — plus fourteen public holidays, roughly seven weeks in total. If your writing is where your thinking happens, you will be at home.
You can say no to someone senior, with a number. You use AI seriously — for prototyping, for analysis, for your own writing — and you read what it produces the way you would read a colleague's work: with respect and suspicion.
English, fluently. Spanish is a genuine advantage day to day, and for your first product especially. Catalan is not required.
We do not care what you studied, and a Scrum certification is neither required nor an advantage.
