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.
