About the role
You own the web — every page on viktor.com, every campaign landing page, every A/B test that runs against real traffic. LP velocity (multiple per week), A/B testing end-to-end (hypothesis → PostHog → winner/loser), site architecture, conversion surfaces. Vibe-coding is core: you ship Next.js/React/Tailwind via Cursor or Claude Code — no design handoff. 5+ years web/UI/UX design with shipped landing pages at scale. Daily AI use required.
