574413 - Senior Front-End Developer (TypeScript, React & Micro Frontends)

Mandatory skills*

We are specifically looking for candidates who can demonstrate

Architectural Awareness: Ability to explain end-to-end application architecture, data flow, and the reasoning behind technical decisions. They must move beyond module-level knowledge to understand how the entire system functions.

Core Fundamentals: Expert-level proficiency in JavaScript and TypeScript. Candidates must explain how frameworks and browser features work internally, rather than simply how to use their APIs.

Web Components Proficiency: Practical, hands-on experience with Custom Elements, Shadow DOM, HTML templates, lifecycle callbacks, event communication, and framework integration (e.g., React).

Micro-Frontend (MFE) Expertise: A explicit understanding of implementation approaches-such as Module Federation, iframes, or build-time packages-including the ability to discuss the trade-offs and justifications for choosing one approach over another.

Problem-Solving: Practical knowledge of accessibility, localization, and responsive design, supported by the ability to articulate the \"why\" behind their technical choices.
