We are looking for a Product UI/UX Designer (Engineer) who will take full ownership and final responsibility for UI/UX quality across the entire product.

This is a senior, high-impact role for an exceptional specialist. You will be the main authority on UI/UX, responsible for ensuring that every interface, flow, and interaction shipped to production is clear, modern, intuitive, and aligned with best UX practices.

All UI/UX-related changes must be reviewed and approved by you before release. You are fully accountable for the UX that reaches users.

In this role, UX is designed and implemented directly in code. You will work hands-on with interfaces using Tailwind and ready-made UI components, collaborating closely with Product, CRO, and Engineering to turn ideas into production-ready UX solutions.

• Final UI/UX Ownership

  • Act as the final decision-maker for all UI/UX changes across the product. Nothing related to UI/UX goes to production without your approval.

• Code-First UX Design & Implementation

  • Design and implement UX directly in code using Tailwind CSS and modern component-based UI libraries (e.g. shadcn, HeroUI or similar).

• Exceptional UI Quality & Clarity

  • Deliver clean, modern, minimalistic, and intuitive interfaces that follow UX best practices and reduce cognitive load for users. Every element must serve a clear purpose.

• UX Ideation & Product Contribution

  • Generate and develop UX ideas aimed at improving usability, clarity, engagement, and overall product value.

• UX Flow & Interaction Design

  • Define and refine user flows, screen logic, interactions, and states to ensure a smooth and predictable user experience.

• Cross-Functional Collaboration

  • Work closely with Product Managers, CRO Managers, and Engineers to translate hypotheses into clear, testable, and scalable UX solutions.

• UX Quality Control

  • Ensure UX implementation is consistent, well-structured, and requires minimal rework after release.

• Highly senior Product UI/UX Designer / UX Engineer with a deep understanding of both UI and UX.

• Strong hands-on experience implementing UX directly in code.

• Solid experience with Tailwind CSS and component-based UI systems.

• Strong product thinking: you understand how UX decisions affect user behavior, retention, and value.

• Experience with subscription-based or performance-driven products is a strong plus.

• Able to work effectively in a high-pressure, high-expectation environment.

• Confident in taking responsibility for final decisions and outcomes.

• Clear, structured communicator.
