• Use RxJS (Observables, Subjects, operators, async pipe) for reactive, event-driven UI flows.
• Implement dynamic component loading and a reusable component-based architecture for large applications.
• Collaborate with UX/design to translate wireframes into responsive, accessible interfaces.

Backend & Data Collaboration

• Write clean, testable, maintainable code and participate in front-end architectural discussions.

Cloud & Tooling (Good to Have)

• Support deployment and operation of front-end apps in Azure (App Service, monitoring, scaling).
• Work within CI/CD pipelines for front-end builds, tests, and deployments.

Additional (Nice to Have)

• Python for tools, scripting, or integration supporting UI work.
• SQL knowledge is a plus.

General / Cross-Cutting

• Debug and troubleshoot complex front-end issues, collaborating across teams as needed.
• Produce clear technical documentation and communicate effectively with technical and non-technical stakeholders.

Required Qualifications - Technical Must-Haves

• Proven experience in architecting large Angular applications.
• Strong understanding of OOP, SOLID, and design patterns in front-end engineering.
• Experience integrating Angular apps with . NET-based RESTful APIs.
• Familiarity with distributed, message-based backends (RabbitMQ, Redis) from a UI integration perspective.
• Solid understanding of web performance optimization (lazy loading, minimizing network calls, caching strategies).

General Requirements

• Experience building and supporting large-scale, production web UIs.

• Strong front-end debugging skills (browser dev tools, network, performance).

• Familiarity with CI/CD and modern front-end build pipelines.

• Strong collaboration and communication skills.
