We help 500k+ students land jobs they love, and we're growing We're a lean, high-output team based in Barcelona. 22 FTEs and growing, €4m+ raised from top investors. We move fast, own our decisions, and push each other to do great work. Marketing here isn't a support function, it's a growth engine, and right now it runs through one person. The Role We need someone who can pick up the entire marketing function and run with it, without much hand-holding. You've owned a channel or a program before, made the calls yourself, and dealt with what happened next, good or bad. You'll report directly to the founders and our Head of Growth. But day to day, you're the one deciding what's worth doing and what isn't. This isn't a role where things get handed to you in a neat brief. You set your own priorities and figure out the rest. Main areas you'll own: sales enablement, product marketing, webinars,



paid acquisition, events (virtual and in-person), and community programs. Typical split: about half sales support and ops, half digital campaigns and content. It shifts depending on the quarter. Start date: ASAP What You'll Actually Do Use AI like it's second nature. You're already running AI tools daily for content, asset generation, campaign work, maybe you've even built a small agent or two to take repetitive stuff off your plate. We need someone who's past the "learning how to prompt" stage. Run events end to end, and own how they go. International virtual career fairs, webinars, touchpoints with talent teams at top companies. Registration, comms, live coordination, the post-mortem after. If something flops, you're the one who knows why and fixes it next time. Own webinars, not just run them. You decide the format and cadence, not just execute someone else's calendar.
