Senior Product Desiner (f/m/d) in Hamburg

We're looking for a Senior Product Designer to join our design team.

You'll take features end to end, from research and flows through to the finished interface, for an analytics platform that mobile gaming studios use every day to decide where their marketing money goes.

You'll also own our design system: the components, patterns and documentation that everything else is built from.

This is a broad role.

You'll do research, interaction design, visual design and system work, and you'll do it in a small team where your decisions ship.

At justtrack, we build a Saa S business that provides app and game publishers with an attractive toolset to manage their entire global growth marketing process.

Starting from managing, analyzing, and automating marketing processes, justtrack enables gathering deep mobile product insights.

As part of the Applike Group (financially backed by media powerhouse Bertelsmann), justtrack has access to industry experts and funding with a long-term growth mindset.

WHAT YOU WILL DO

• Work AI-First: Use AI tools as a standard part of your design process, research synthesis, copy, design generation and iteration, with the judgement to know where the output needs your correction.
• Own Features End to End: Take features from problem statement through research, flows and interface to shipped result, without handing off between layers.
• Own the Design System: Build, document, and evolve our design system, components, variants, states, tokens, and decide how it changes as the product grows.
• Design for Data Density: Design charts and data-heavy screens where information hierarchy and readability matter more than decoration.
• Design AI-Assisted Surfaces: Shape how our AI features present their output, transparency, confidence, review steps, and what happens when the model gets it wrong.
• Work Closely with Engineering: Specify components so frontend can build them directly, and review the built result against the design.
• Talk to Users: Run research and usability tests with gaming studios and internal stakeholders, and turn what you learn into design decisions.

WHO YOU ARE

• Experience: You have 5+ years in product design or a comparable end-to-end design role, ideally on a complex Saa S product.
• Background: A degree in design, HCI, or a related field, or equivalent practical experience.
• AI Fluency: You already work with AI tools day to day and have a clear view of where they help and where they don't.
• End-to-End Craft: You're strong across the whole range: research, flows, interaction and visual design, rather than deep in one and dependent on others for the rest.
• Design System Expertise: You've built and maintained a design system in production, including documentation and the governance decisions that keep it coherent.
• Tools: Expert in Figma. It's where our final designs live, and where our design system is built and maintained.
• Portfolio: You have a strong portfolio showing end-to-end work, the problem, your decisions, the finished interface, and what it changed.
• Collaboration: You work well with product owners and engineers, articulate your rationale clearly, and can hold a position without stalling the work.
• Optional: Experience designing for analytics, data visualization, or another data-dense environment.
• Optional: Familiarity with front-end frameworks (e. g. React) and component development tools (e. g. Storybook).
• FUEL FOR THE JOURNEY: BENEFITS TO SUPPORT YOUR AMBITIONS
• Invest in Your Future: Regular feedback and our development program support your growth, helping you expand your skill set and achieve your career goals.
• Easy Arrival to justtrack: From signing to settling in Hamburg, we’ve got you covered.
