This is your opportunity to take on a leadership-oriented technical role, guiding backend engineering practices while remaining hands-on in building secure, scalable, and reliable services that power EY’s digital platforms.

Position Overview

The Frontend Software Engineer at EY Luxembourg's Digital Factory plays a key role in designing and delivering modern, high-quality web user interfaces for enterprise-grade digital products. This position places a strong emphasis on fundamentals in JavaScript and TypeScript, adherence to web standards, accessibility, and ensuring long-term maintainability of solutions. While the role values broad technical versatility, there is a strong focus on modern React-based development, in particular React and Next.js, alongside Angular expertise.

  • Contribute to framework upgrades, migrations, or technology evolution, prioritizing the reduction of technical debt.
  • Avoid vendor or framework lock-in by favoring standards, clean abstractions, and well-defined contracts.
  • Write clean, well-structured, and testable JavaScript/TypeScript code that emphasizes readability and maintainability.
  • Develop unit, integration, and end-to-end tests utilizing appropriate testing frameworks and tools.
  • Participate in code reviews and collaborate on shared frontend standards and best practices.
  • Document frontend architecture decisions, patterns, and contribution guidelines.

Performance and User Experience

  • Apply best practices for frontend performance, including lazy loading, efficient rendering, and asset optimization.
  • Ensure consistent behavior across various browsers, devices, and screen sizes.
  • Diagnose and resolve frontend performance and usability issues using standard tools.

Security and Compliance Awareness

  • Implement secure frontend development practices to protect against common web vulnerabilities.
  • Demonstrate awareness of risks associated with third-party dependencies, licensing, and vulnerability management.
  • Follow enterprise security, privacy, and compliance requirements.

Operations and Continuous Improvement

  • Support production frontend applications through monitoring, debugging, and resolving issues.
  • Contribute to enhancing developer experience by developing shared libraries, improving tooling, and automating processes.

Qualifications
