React developer

At GBL Tech we drive high-impact technology careers through specialization and scale. We operate across critical digital ecosystems—from Fintech to Smart Industry—connecting talent with technically challenging projects and modern stacks.

The Project

You will join a telecom project focused on platforms that measure Quality of Service (QoS) and Quality of Experience (QoE) across mobile and broadband networks.

The ecosystem combines modern web applications, mobile solutions and network diagnostic tools to collect real-time metrics such as latency, throughput and packet loss.

These solutions provide operators with end-to-end visibility of network performance from the customer perspective, with a strong focus on intuitive and high-performing user interfaces built with React.

What You’ll Be Doing

• Develop and maintain responsive and high-performance web applications using React.
• Build reusable components and front-end libraries for scalable application architecture.
• Integrate front-end applications with backend services and APIs.
• Collaborate with UX/UI designers to implement user-friendly and visually consistent interfaces.
• Optimize applications for maximum speed and scalability across devices and browsers.
• Ensure code quality through best practices, testing and code reviews.
• Work closely with cross-functional teams in Agile environments, contributing to sprint planning and delivery.
• Troubleshoot and debug issues, ensuring smooth user experience across platforms.
• Contribute to continuous improvement of front-end architecture and development processes.
