Product Designer

We're looking for a passionate and experienced Product Designer to join our team as we continue to scale. 🚀 You'll own user flows end to end inside one of our product squads , helping AppTweak ship an app-marketing platform that feels like one product while AI reshapes both our industry and the design craft itself. You'll report to the Head of Product Design.

Location: Brussels, hybrid setting, min. 3 days per week at the office. What you'll do Own complete user flows in a cross-functional squad: from defining the problem with your PM to polished, edge-case-complete designs engineering can build from, through to the 30-day follow-up after release. At AppTweak, designers close the loop on what they ship. Hand engineering working prototypes, not just static specs: we prototype with agentic AI tools (Cursor), and shipping simple UI fixes directly in the codebase is part of the job (we'll teach you how).

Raise the quality of the existing product, not only new features: spot and fix smaller "paper cuts" as you use AppTweak daily, and turn user feedback and usage signals into shipped improvements. Strengthen our design system: contribute documented, reusable components and learn when to use it, when to evolve it, and when to break it. Challenge scope, definitions and requests when they don't serve the user, and explain the why behind your design decisions to your squad.

Grow along a transparent career framework: written expectations per level, evidence-based promotion gates, and mentorship from a senior member of the team from the start.
