Overview

We are looking for a highly motivated and experienced Mid-Level UI Developer to join our front-end team. In this role, you’ll help shape the user experience of modern, high-performance web applications by translating design mockups into scalable, reusable, and accessible user interfaces.

As a Mid-Level Developer, you’ll independently build and maintain UI components using Vue.js (Composition API) and Pinia, collaborate across teams to align UI architecture with business needs, and contribute meaningfully to our agile development process. You’ll also lead by example in code quality, testing practices, and mentoring junior developers.

This is a great opportunity for someone who’s passionate about building engaging interfaces and ready to take ownership of front-end development in a collaborative product environment.

Key Responsibilities

• Architect, develop, and maintain front-end applications using Vue.js (Composition API) and Pinia for state management.
• Translate complex UI/UX designs into high-performance, reusable components.
• Independently contribute to front-end development tasks with solid JavaScript concepts and problem-solving skills.
• Collaborate with designers, product managers, and back-end engineers to align development with business goals.
• Lead technical discussions in sprint planning, story estimation, and UI architecture design.
• Write robust unit and integration tests using Vitest and Vue Test Utils to ensure code stability and maintainability.
• Debug and resolve UI issues related to layout, rendering, responsiveness, and browser compatibility.
• Optimize front-end performance through lazy loading, code splitting, and other best practices.
• Mentor and support junior developers through code reviews, pairing, and technical guidance.
• Proactively contribute technical suggestions and improvements to enhance code quality, user experience, and application scalability.
• Analyze user behavior, feedback, and analytics to suggest and implement UX/UI improvements.

Requirements

• 4-6 years of professional front-end development experience.
• Strong expertise in Vue.js, especially with the Composition API, Vue Router, and Pinia.
• Working experience in frameworks like Vue.js (preferred) or React/Angular.
• Solid experience with modern JavaScript (ES6+), including async/await, destructuring, modules, and promises.
• Familiarity with React.js fundamentals such as hooks, state management, and component lifecycle.
• Proficiency in testing with Vitest, Vue Test Utils, and debugging using browser developer tools.
• Experience integrating with RESTful APIs and handling asynchronous data flows.
• In-depth understanding of responsive design principles and cross-browser compatibility.
• Awareness of accessibility standards (WCAG) and implementation practices.
• Proven ability to refactor legacy components and build reusable, modular UI libraries.
• Strong communication skills and ability to collaborate effectively in a fast-paced Agile environment.
• Demonstrated ability to work as an independent contributor, proactively manage responsibilities, and contribute ideas for technical and process improvements.
• Comfort interpreting design intent—even when specs are incomplete—and proposing UX solutions.

Preferred, Not Required

• Experience working with Genesys Cloud or other call center technologies.
• Familiarity with performance analysis and optimization using tools like Chrome DevTools, Lighthouse, or Web Vitals.
• Experience with design systems, style guides, or component libraries (e.g., Storybook).
