Are you an analytical frontend engineer who thrives on complex data flows, high-security applications, and state-of-the-art tech stacks? For a leading global telecommunications provider, we are seeking a Senior Frontend Developer (Angular) to join a dedicated DevOps product team that builds and operates critical applications for Business Continuity Management and Penetration Test Management across the entire enterprise. As the backend is currently being modernized to a FastAPI and AWS containerized architecture, you will take the lead on the user interface, ensuring that complex security data is translated via a flawless Angular/NgRx architecture into a consistent, secure, and world-class user experience.

Frontend Architecture, State Management & DevOps

As a Frontend Developer, you will take end-to-end feature ownership of the security platform's interface, operating firmly under a "you build it, you run it, you own it" mentality.

• State Management & Architecture: Structure, optimize, and manage complex application state and heavy data flows using NgRx (Store, Effects, Selectors, and Entity patterns).
• Component Design: Develop reusable component libraries, unified design systems, and maintainable UI architecture patterns using the Angular Material library.
• API Consumption & Integration: Seamlessly integrate the frontend with the modernized backend APIs, adhering to OpenAPI/Swagger documentation and JSON:API standardization patterns.
• Quality Assurance & Testing: Write clean code with an extreme eye for detail, implement robust unit testing (Jasmine/Karma), optimize bundles (lazy loading), and collaborate within automated CI/CD pipelines.

• A minimum of 4 years of proven experience as a Software Engineer in complex, data-heavy, or security-sensitive enterprise environments. Active experience in an Agile/Scrum DevOps setup is mandatory.

• Core technical stack (Day 1 credible):
  • Deep production-grade experience with the Angular Framework (latest versions, component architecture, dependency injection, and lifecycle management).
  • Advanced skills in TypeScript (including advanced types, decorators, interfaces, and generics).
  • Extensive experience with NgRx State Management (Store, Effects, Selectors).
  • Strong frontend fundamentals (HTML, modern CSS like Grid/Flexbox) and Angular Material UI components.
  • Advanced Git workflow practices and code-review experience.
•  Strong plusses (expected to grow into):
  • Practical experience with Docker containerization and CI/CD automated deployment workflows.
  • Unit testing experience (Jasmine/Karma) and knowledge of API standards (JSON:API, OpenAPI).
  • Framework versatility: real-world feature delivery experience in React or Vue is highly valued.
• Soft skills & culture: A proactive, self-starting team player who prioritizes team alignment and business outcomes over isolated output. Excellent written and verbal communication skills in English are mandatory (the team is fully international).
