Mainloop is a new engineering team inside an established international group. We are in Barcelona, we are being built from scratch this year, and we have the backing, the customers and the product portfolio of a company that has been around for decades. You get the interesting part of a new team without the part where you check whether payroll clears.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. Over your first two to three years here you work through a defined body of knowledge — how we build, how we run products, how a need becomes a spec becomes working, adopted software — and when you can demonstrably run a product our way, you are awarded the Mainloop Barcelona certificate. 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.No rota, no pager. Flights, your first month's accommodatio
