We're building and scaling a high-growth D2C product used by hundreds of thousands of customers globally, and we're now entering a phase where UX is a core growth lever. We're adding new capabilities, expanding the product, and focused on improving retention, activation, and funnel performance — and we need a UX leader who can drive that.
This is not a 9–5 role. It's a high-ownership, high-impact position for someone who wants to build systems, lead people, and directly influence growth metrics.
Co budeš dělat
- Take full ownership of UX, design quality, and user journeys across the product.
- Turn UX into a measurable growth lever — directly improving activation, retention, and conversion.
- Work closely with Product and Growth to design and optimize funnels, onboarding, paywalls, and retention loops.
- Audit and continuously improve the end-to-end user journey — from acquisition through long-term retention.
- Analyze product analytics independently — Mixpanel funnels, cohort analysis, retention curves, drop-off patterns.
- Connect UX decisions directly to business metrics — activation rate, retention curves, LTV, conversion.
- Define hypotheses, experiments, and success metrics for every UX initiative.
- Use session recordings (Clarity, FullStory, Hotjar), heatmaps, and behavioral data to identify friction points.
- Proactively request and define new analytics instrumentation and reporting needs with the data team.
- Validate UX changes through A/B testing (GrowthBook or similar) — hypothesis, implementation, result analysis.
- Define, enforce, and evolve a clear, scalable design system (implemented directly in frontend, not Figma-first).
- Lead and direct designers and frontend engineers involved in UI/UX work — set the definition of done.
- Set the visual and interaction quality bar across the product.
- Establish a structured research practice — define priorities, run interviews, surveys, and usability tests.
- Translate raw research into prioritized, actionable product decisions.
- Direct and level up the existing UX researcher on the team — provide structure, frameworks, and clear priorities.
