Summary ✨ AI‑Generated

A senior frontend engineering role focused on building scalable, reusable interfaces with modern React, Next.js, and advanced TypeScript. You will optimize web performance, integrate REST and GraphQL services, contribute to a design-system approach, and improve delivery through CI/CD and robust unit and integration testing within an Agile team. Experience with media streaming, accessibility, and common project collaboration tools is a plus. Occasional on-call or evening/weekend support may be required.

Highlights

Work on modern React and TypeScript frontend engineering with a strong focus on reusable architecture, performance, API integration, automated delivery, testing, and Agile practices. Additional exposure to streaming, accessibility, and collaboration tools is valued.

Description

The role requires deep React 19+ and advanced TypeScript skills to build reusable, strongly typed components, plus strong web performance expertise (caching, CDN optimization, Core Web Vitals). You will integrate REST/GraphQL APIs, contribute to a design-system-oriented styling approach, and industrialize delivery with Git/GitLab/Jenkins CI/CD and solid unit/integration testing in an Agile environment. Media/video streaming, accessibility, and Jira/Confluence are valued extras; occasional on-call/evening/weekend interventions may be needed.
