Summary ✨ AI‑Generated

A senior frontend engineering role for an experienced React and TypeScript specialist building reusable, strongly typed interfaces with a strong emphasis on web performance and Core Web Vitals. You will integrate REST and GraphQL services, contribute to a design-system approach, and improve software delivery through CI/CD, automated testing, and Agile practices. Experience with streaming media, accessibility, and collaboration tools is an advantage. Occasional after-hours or on-call support may be required.

Highlights

Work on modern, strongly typed frontend applications with a focus on reusable architecture, high web performance, API integration, automated delivery, and robust testing. The role also offers exposure to design systems, accessibility, and media technologies.

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.
