About the role

Key responsibilities & impact

Lead the end-to-end design process, for client projects and the NineTwoThree brand, from concept to developer-ready handoff.
Work inside our existing component system (Chakra UI and its Figma UI Kit): reuse and extend it, customizing per client with minimal divergence and minimal engineering rework, instead of reinventing components.
Produce wireframes, prototypes, and high-fidelity UI in Figma to communicate solutions and test hypotheses.
Conduct competitive analysis and usability testing to validate decisions, favoring familiar, proven patterns over trends.
Treat developer implementation cost as a first-class design constraint: prefer the solution that ships fastest from our component library over the one that looks the most novel.
Innovate in information architecture and layout: decide what to surface, what to hide, and where things live, so the main workspace gets the screen space rather than endless menus, filters, and navigation.
Collaborate with product managers, engineers, and stakeholders to translate complex requirements into usable designs, and defend your decisions with user needs and business goals.
Speed up the design process with AI tools, and help raise the team's craft and design culture.

Requirements

What you’ll need

At least **5 years of experience as a UI/UX Designer**, with a strong portfolio showcasing knowledge of **UX principles**, user flows, and designing data-dense internal tools, admin panels, dashboards, or B2B/enterprise applications (not only consumer or brand work).
Experience working in structured, fast-paced environments with clear processes, tight deadlines, and asynchronous collaboration across departments, comfortable managing multiple projects at once.
Experience working as part of a multi-designer team, contributing to shared systems and giving/receiving design feedback.
**Proven ability to design within an established component library** (Chakra UI, MUI, Ant Design, or similar), with a working sense of how design choices translate into front-end (React/Chakra) implementation effort.
Proficiency in Figma, including team libraries, auto layout, component properties, and prototyping.
Solid understanding of user-centered design principles and usability best practices.
Knowledge and experience with Google Material and Apple Design Guidelines.
Strong fundamentals in layout, grids, information hierarchy, and responsive/interactive design.
Excellent written and spoken English (Upper-Intermediate or higher) for remote collaboration.
Experience designing for AI-driven web and mobile applications.
Attention to detail and a strong sense of usability and information hierarchy.
