Dentsu International Switzerland AG
Senior Frontend Engineer - Angular
📍 Zürich
Rolle und Verantwortlichkeiten
Lead the design and evolution of Angular application architecture — module federation, standalone components, lazy loading, and state management patterns. Own and extend the shared component library and design system built with Angular Material and custom SCSS tokens. Define coding standards, review guidelines, and architectural decision records (ADRs) for the frontend chapter. Drive migration and upgrade paths across major Angular versions with minimal disruption to delivery squads. Evaluate and introduce new Angular features (Signals, Deferrable Views, SSR with Angular Universal) where they bring clear benefit. Implement complex banking features: payment flows, account overviews, transaction history, document centre, and secure messaging. Build secure authentication and session management UIs integrating with OAuth2 / OpenID Connect and MFA flows. Develop and maintain multilingual (DE/FR/IT/EN) interfaces using Angular i18n and ngx-translate, respecting Swiss linguistic and formatting conventions. Collaborate with backend teams to design and consume RESTful and GraphQL APIs with strong typing (OpenAPI codegen, Apollo). Ensure pixel-perfect implementation of UX designs from Figma, maintaining consistency across breakpoints and devices. Profile and optimise Angular application performance: bundle size, Core Web Vitals, change detection strategy, virtual scrolling. Write comprehensive unit tests (Jest / Jasmine / Karma) and integration tests; contribute to E2E test suites (Cypress / Playwright). Enforce accessibility standards (WCAG 2.1 AA) across all components, supporting screen readers and keyboard navigation. Conduct thorough code reviews and contribute to a culture of quality and continuous improvement. Apply OWASP Top 10 mitigations in frontend code: XSS prevention, CSP headers, secure cookie handling, and CSRF protection. Implement Content Security Policies, Subresource Integrity, and other hardening measures required in a banking context. Support security audits and penetration testing remediation cycles. Maintain awareness of FINMA digital banking guidelines as they apply to frontend data handling and user consent.
