Frontend UI Developer

About the job

As a Frontend UI Developer (3–5 years experience), you will create visually compelling, performant, and intuitive user interfaces, contributing to design systems and collaborating across engineering, product, and design teams. You’ll also have the opportunity, as a plus, to make minor backend changes—ideally with some experience in Golang APIs and microservices. Key Responsibilities • Develop, maintain, and evolve scalable design systems and UI components in collaboration with designers and engineers. • Translate product requirements and UX/UI mockups into responsive, accessible web interfaces using modern frameworks (React.Js preferred). • Work closely with backend and DevOps teams, supporting integrations and occasionally making minor backend adjustments, ideally with Golang experience. • Conduct comprehensive testing, using automated UI/unit test frameworks, to ensure code quality and reliability. • Optimize UI performance through profiling, refactoring, and best-practice implementation. • Manage codebase using Git, participate in code reviews, and help drive engineering process improvements. • Integrate and maintain third-party tools, like Storybook, and suggest new technologies for improving developer workflow. • Advocate for accessibility and inclusivity in UI development. Core Skills • Proven expertise in HTML5, CSS3, JavaScript (ES6+), and React.Js (or equivalent modern frameworks). • Strong grasp of design systems, responsive design, cross-browser compatibility, and accessibility standards. • Experience translating complex design requirements into maintainable, scalable code. • Familiarity with UI testing (Jest, Cypress, Testing Library) and CI/CD automation. • Experience with version control and collaborative development (Git, PR workflows). • Ability to identify and resolve performance bottlenecks. • Excellent communication and cross-functional teamwork skills. Nice-to-Have • Experience with backend development or API collaboration, ideally with Golang for minor changes. • SaaS product development background, and experience working with observability or monitoring tools. • Knowledge of CSS preprocessors (Sass, Less) and CSS-in-JS solutions. • Experience with build systems (Webpack, Vite) and Agile/Scrum delivery processes.
