Lead the modernization of a critical case management platform by defining front-end architecture and driving technical excellence across Angular and Rust. You will shape scalable web and desktop applications that directly support vulnerable people and high-stakes administrative decisions.

CONTEXT

Our client, a major player in its sector, is undertaking a landmark modernization of its eDossier platform—a digital backbone that handles sensitive, life-changing cases with the highest standards of confidentiality and reliability. The program is not merely a technical upgrade; it is a strategic leap toward a more humane, efficient, and resilient public service. As the Lead Frontend Engineer, you will define the architectural vision for a new generation of web and desktop applications, ensuring they are fast, secure, accessible, and maintainable for years to come.

  • Develop scalable, reusable components and libraries that can be shared across web and desktop targets.
  • Collaborate with back-end engineers, UX designers, and product owners to translate requirements into elegant interfaces.
  • Conduct code reviews, enforce best practices, and champion performance, security, and accessibility.
  • Drive continuous integration and delivery pipelines for front-end assets.
  • Evaluate emerging technologies and propose pragmatic improvements to the existing stack.

EXPECTED ACHIEVEMENTS

  • Deliver a modern, modular front-end foundation that reduces technical debt and accelerates future feature delivery.
  • Establish a high-performing front-end guild with clear standards, documentation, and reusable patterns.
  • Ensure the eDossier platform meets demanding usability, security, and performance benchmarks.
  • Successfully migrate legacy interfaces to the new architecture with minimal disruption to critical operations.
  • Leave a lasting technical legacy that supports the client's mission until at least the end of 2028.

ENVIRONMENT
