ABOUT THE ROLE & TEAM

We are seeking a highly skilled Senior UI Developer to contribute to a major redesign and modernization project. This is a greenfield initiative focused on building a modern, scalable, microservices-driven architecture with a strong emphasis on micro‑frontend patterns and a next‑generation user experience.

The ideal candidate brings deep expertise in modern JavaScript frameworks—primarily React—and demonstrable experience designing and delivering UI solutions within distributed, cloud‑ready architectures.

WHAT YOU’LL DO

• Design, develop, and maintain rich, responsive user interfaces using React and micro‑frontend architectures.
• Collaborate closely with architects, backend engineers, and UX teams to implement UI components aligned with product requirements and system design.
• Apply solid application design principles and patterns to create scalable, maintainable, and testable UI solutions.
• Contribute to the evolution of a microservices‑based application ecosystem, ensuring seamless integration between front-end and backend services.
• Develop technical designs for small to medium-scale systems or for features within large applications.
• Evaluate and articulate the trade-offs and risks associated with technical decisions, tools, and implementation approaches.
• Ensure high code quality using modern development practices, including GitHub Copilot, pair programming, and AI-assisted coding tools (e.g., Vibe coding workflows).
• Utilize cloud technologies—preferably Microsoft Azure—to support deployment, scalability, and performance of UI services.
• Follow best practices for version control, source code management, and collaborative development using Git and GitHub.
• Participate in code reviews, technical discussions, and architectural decision-making.

ABOUT YOUR SKILLS

• Strong proficiency in React, modern JavaScript/TypeScript, and component‑based UI architecture.
• Hands-on experience with micro frontends and distributed UI composition patterns.
• Solid understanding of microservices architecture and how front-end applications integrate with distributed backend systems.
• Demonstrated ability to apply software design concepts such as modularity, separation of concerns, and design patterns.
• Experience working with Azure or similar cloud environments.
• Advanced knowledge of version control and collaborative development workflows (Git/GitHub).
• Strong understanding of standard software development principles, methodologies, and best practices.
• Ability to design and develop solutions for small to medium systems, or contribute effectively to large-scale application features.
• Clear understanding of technical trade-offs, performance considerations, and risk impacts in front-end engineering decisions.
• Familiarity with GitHub Copilot, AI-assisted development tools, and modern collaborative coding methods.

NICE-TO-HAVE

• Experience with CI/CD pipelines for UI deployments.
• Knowledge of UX principles and usability best practices.
• Exposure to containerized application environments (Docker, Kubernetes)
