Core Responsibilities

Primary Functions

Design, implement and maintain modular, reusable, and testable Angular components, services, directives, and pipes following best practices for component-based architecture and scalable code organization.
Translate product requirements and UX designs into robust Angular feature implementations, ensuring pixel-perfect UIs using HTML5, CSS3, SCSS, and responsive design techniques for cross-device compatibility.
Build and maintain complex single-page applications (SPAs) using Angular CLI, implementing routing, lazy loading, and feature modules to optimize initial load and runtime performance.
Architect and implement application state management using NgRx, Akita, or Redux patterns, including actions, reducers, selectors, effects, and entity adapters to ensure predictable state transitions.
Integrate front-end code with backend services via RESTful APIs and GraphQL, design efficient HTTP clients using Angular HttpClient, and handle authentication/authorization flows (OAuth2, JWT, or similar).
Implement reactive programming patterns using RxJS observables and operators, manage subscriptions, error handling, and advanced stream composition to create responsive UIs and side-effect management.
Apply performance optimization strategies including AOT compilation, Ivy renderer considerations, change detection strategies (OnPush), bundle splitting, tree shaking, and Webpack optimization to reduce payload and improve runtime speed.
Develop and maintain unit tests, integration tests and end-to-end (E2E) tests using Jasmine, Karma, Jest, and Cypress or Protractor, ensuring CI pipelines validate quality and prevent regressions.
Implement accessibility (a11y) best practices, semantic HTML, ARIA roles and keyboard navigation to deliver inclusive web experiences that meet WCAG guidelines.
Build Progressive Web App (PWA) features using service workers, caching strategies, offline support and manifest configuration to improve UX on unreliable networks.
Establish and follow front-end coding standards, code style guidelines, linting (TSLint/ESLint), and enforce consistent formatting via Prettier, ensuring maintainable codebases and predictable reviews.
Participate in and lead code reviews, providing constructive feedback focused on performance, reusability, security, testability, and alignment with architectural goals.
Design and execute migration strategies for upgrading Angular versions (e.g., Angular 8 → 9+), manage breaking changes, leverage the Angular update schematics and test migration outcomes.
Implement client-side security practices such as XSS prevention, secure storage patterns, CSRF protection, content security policy (CSP) considerations and safe handling of third-party scripts.
Collaborate with backend and infrastructure teams to support SSR (Angular Universal) for SEO-sensitive pages, server-side rendering performance tuning, and caching strategies.
Instrument front-end error tracking and observability (e.g., Sentry, LogRocket), capture performance metrics (TTFB, FCP, LCP, CLS) and work with teams to triage and resolve production issues.
Configure and optimize continuous integration and continuous deployment (CI/CD) pipelines for front-end releases (Azure DevOps, GitHub Actions, Jenkins, CircleCI), automate build verification and release promotion.
Lead feature discovery, technical feasibility analysis, and deliverable estimation; break down epics into actionable user stories and tasks for Agile sprints.
Mentor junior developers and onboard new engineering hires with pairing sessions, knowledge-sharing, and documentation of architectural patterns and common solutions.
Drive front-end architecture discussions: monorepo vs polyrepo, module boundaries, micro-frontend strategies (single-spa, Module Federation), and library design for shared UI components.
Create technical documentation, component libraries, Storybook stories, and design-system integrations to enable consistent UI development and faster feature delivery.
Troubleshoot and resolve complex production incidents, hotfix priority issues, and coordinate rollbacks or patch releases when needed to maintain application uptime.
Prototype new UI patterns, evaluate third-party libraries and frameworks, and propose platform improvements that reduce technical debt and accelerate delivery velocity.

Secondary Functions

Support on-call rotations for production front-end incidents and collaborate with SRE/DevOps to diagnose client-side faults and network-related issues.
Produce and maintain public-facing and internal documentation: API integration guides, component usage docs, Storybook catalogs and architecture decision records.
Work closely with UX and product teams to run usability testing, A/B experiments and implement analytics tags for feature telemetry and conversion tracking.
Assist with performance budgets, front-end monitoring dashboards, and initiatives to continuously lower Core Web Vitals and other user-centric performance metrics.
Contribute to hiring and interviewing processes by evaluating technical skills, reviewing code challenges, and participating in recruitment debriefs.
Create demo-ready prototypes for stakeholders to validate concepts and gather early feedback before full implementation.
Participate in sprint planning, refinement sessions, and retrospective meetings to improve delivery processes and team collaboration.
Provide ad-hoc support for cross-functional data or analytics requests that require front-end instrumentation or client-side data collection.
Help the organization adopt front-end standards and tooling (linters, testing frameworks, CI templates) and drive platform-wide consistency.
