We are looking for a Senior Frontend Developer with deep Angular expertise to join the team powering an e‑banking platform for a BFSI client. You will be a key contributor to the web banking application across all four of Switzerland’s national languages, building secure, performant, and accessible user experiences that meet the rigorous demands of a regulated financial environment.
Key Responsibilities Lead the design and evolution of Angular application architecture (module federation, standalone components, lazy loading, 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 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.
Qualifications Must‑Haves:
3+ years of professional frontend development with Angular (v12 or later).
Strong TypeScript skills – strict, well‑typed code and understanding of the Angular compiler.
Expert‑level RxJS knowledge: design reactive data flows and handle complex async scenarios confidently.
Experience building and maintaining large‑scale, production Angular applications.
Solid understanding of web security fundamentals relevant to frontend: XSS, CSRF, CSP, secure authentication.
Experience with NgRx or equivalent state management in non‑trivial applications.
Strong sense of UI quality: accessibility, cross‑browser compatibility, responsive design, and performance.
Collaborative mindset with demonstrated experience mentoring or leading frontend engineers.
Strong Plus:
Experience in financial services, banking, or another security‑sensitive regulated industry.
Familiarity with micro‑frontend architecture (module federation, single‑sp).
Hands‑on experience with Nx monorepo tooling for multi‑app/multi‑lib workspaces.
Contributions to open‑source Angular projects or internal design systems.
Knowledge of Angular Universal (SSR) or static pre‑rendering for web banking performance.
Experience integrating Angular apps with OAuth2/OIDC providers (Keycloak, AzureADB2C).
