Contract

We are seeking an accomplished Advanced UI Angular Developer to design, develop, and optimize feature-rich, enterprise-grade web applications. The ideal candidate brings deep expertise in Angular, TypeScript, and modern front-end architectures, with a proven track record of delivering scalable, accessible, and high-performance UI solutions. You will collaborate with product, UX, and backend teams to drive an exceptional user experience.

Key Responsibilities

  • Lead the development of complex Angular applications, ensuring robust performance, scalability, and maintainability.
  • Architect front-end solutions including state management, routing, lazy loading, forms, and component libraries.
  • Translate designs into high-quality, responsive, accessible code (WCAG 2.x) with pixel-perfect accuracy.
  • Build and maintain a reusable UI component library and design system; establish guidelines for consistency and reusability.
  • Optimize front-end performance through advanced techniques (change detection strategies, ahead-of-time compilation, code-splitting, caching).
  • Integrate with backend services (REST/GraphQL) and define contract-driven development with strong typing and comprehensive error handling.
  • Drive quality through automated testing (unit, integration, end-to-end) and participate in CI/CD pipelines.
  • Perform code reviews, mentor mid-level and junior developers, and provide technical leadership in architecture discussions.
  • Collaborate in Agile ceremonies, write clear technical specifications, user stories, and acceptance criteria.
  • Ensure security best practices in the front-end (input validation, secure storage, OAuth/OpenID Connect).
  • Stay current with Angular ecosystem, TypeScript, and front-end trends; evangelize improvements across teams.

Required Qualifications

  • 12+ years of professional front-end development with extensive Angular experience (v11+ or newer); strong command of Angular architecture, components, directives, pipes, services, RxJS, and Angular CLI.
  • Advanced TypeScript proficiency; solid JavaScript (ES6+), HTML5, and CSS3/Sass skills.
  • Deep experience with state management (NgRx, Akita, or similar) and advanced RxJS patterns.
  • Strong experience consuming RESTful APIs and/or GraphQL; ability to design and consume API contracts with robust error handling.
  • Proficiency with testing frameworks (Jasmine/Karma, Jest) and test-driven development (TDD/BDD).
  • Experience with front-end build tools (Webpack, ESLint, Prettier) and performance profiling.
  • Solid understanding of accessibility (WCAG) and responsive design principles.
  • Familiarity with server-side rendering (Angular Universal) and PWA concepts a plus.
  • Experience with CI/CD, Git workflows, and collaboration with DevOps for automated deployments.
  • Excellent problem-solving, debugging, and communication skills.

Preferred Qualifications

  • Experience with Angular Material or other UI component libraries; governance of design systems.
  • Exposure to back-end languages (Node.js, Java, .NET) to coordinate with backend teams.
  • Domain experience in finance, healthcare, e-commerce, or similar industries.

Familiarity with micro-frontend architectures and modern deployment strategies.
