Founding AI Engineer

Software Engineering, Data Science EUR 150k-220k / year + Equity Posted on Jun 13, 2026 HelloPrint is on a mission to become the world's leading infrastructure for customizable printed products. From our offices in Rotterdam and Valencia, 120+ professionals from 20+ nationalities are building an AI-first company that scales output faster than headcount. We're at EUR 100M revenue and aiming to disrupt a trillion-dollar industry. Every hire we make needs to help get us there. With our new approach, we ship in a week what used to take a year, and we are looking for someone who raises that bar further. HelloPrint is not exploring, we are completely transforming into a fully AI-first organisation. The entire platform is being rebuilt from the ground up: new frontend, new pricing engine, new content engine, new product engine; Everything ready for an agentic future. No one on the team writes code manually for what these systems handle. Why this role exists: We can find excellent engineers, but what we're looking for are people for whom building and commercial thinking are not two separate things. As a founding AI engineer, you will work directly alongside our founding team, including Hans (CEO) and Michael (CIO / Chief AI Officer). We have no hierarchy, no management layers and no decision trees. Everyone at HelloPrint builds, the founding team included. The expectation for this role is identical to every other builder: see the highest-impact problem, own it, ship it, measure it, move to the next one. This role is not for people who got into AI because it became important. It is for people who have been building since before anyone called it a career. The kind of person who coded as a teenager, shipped their first thing before anyone asked, and has never really stopped. Who finds it genuinely difficult to explain why they build: it is just what they do. Who would rather spend a Sunday solving a hard systems problem than almost any...
