About the Role

We are seeking a UI/UX Front-End Engineer who combines strong user experience design capabilities with hands-on front-end development expertise. Success in this role requires strong UI/UX design ownership supported by hands-on front-end engineering capability. The engineer will work closely with UX designers, product owners, and engineering teams to translate design concepts into interactive prototypes and implementation-ready experiences, bridge communication gaps, and make practical design updates when needed. The ideal candidate has a strong portfolio, an eye for visual and interaction design, experience using AI-assisted workflows for rapid prototyping, and the ability to deliver responsive experiences across desktop and mobile web views in a fast-paced product environment.

Key Responsibilities

• Develop production-ready front-end components using React or Angular, JavaScript, TypeScript, HTML5, and CSS3.
• Create and maintain reusable components, design-system patterns, UI specifications, and developer handoff documentation.
• Optimize designs and front-end experiences across desktop, tablet, and mobile web views using responsive and mobile-first practices.
• Use Generative AI and AI-assisted tools to accelerate design exploration, workflow adoption, prototyping, code generation, and iterative validation.
• Present portfolio work, prototypes, design rationale, trade-offs, and implementation considerations to product, design, engineering, and customer stakeholders.
• Facilitate design reviews, clarify requirements, resolve UX and engineering constraints, and drive decisions across cross-functional teams.
• Work effectively in fast-paced, high-velocity product environments with evolving priorities, rapid feedback cycles, and iterative releases.
• Support usability validation, accessibility reviews, cross-browser testing, performance optimization, code reviews, and release readiness.

Required Qualifications

• 6 8 years of experience in UX design, UI engineering, UX engineering, product design, or front-end development roles with substantial design ownership.
• Demonstrated experience in a role weighted toward UI/UX design while retaining hands-on front-end implementation capability.
• Should have design portfolio and should be able to demonstrate design concepts. A strong portfolio showing the end-to-end design process, including problem framing, user flows, prototypes, design decisions, iterations, and delivered outcomes.
• Candidate must have hands on experience on one of the design tools i.e., Figma, Adobe XD, Canva.
• Strong understanding of user-centered design, interaction design, information architecture, usability, accessibility, and visual-design principles.
• Hands-on experience converting design concepts into interactive prototypes and implementation-ready front-end solutions.
• Strong proficiency in React or Angular, JavaScript, TypeScript, HTML5, and CSS3.
• Experience designing and optimizing responsive experiences across desktop, tablet, and mobile web views.
• Hands-on experience using Generative AI or AI-assisted tools to improve design workflows, accelerate prototyping, and support front-end development.
• Experience collaborating with product owners, UX designers, engineering teams, and business stakeholders throughout the product lifecycle.
• Ability to communicate design rationale, technical considerations, trade-offs, constraints, and recommendations clearly to diverse stakeholders.
• Experience working in Agile, fast-paced, and high-velocity product teams with rapidly changing priorities.
• Working knowledge of REST API integration, cross-browser compatibility, accessibility standards, performance optimization, and source-control practices.
• Exposure to mobile application development using React Native, Flutter, Ionic, or a comparable framework is an advantage.
