About the Role

We are seeking a highly experienced and passionate Senior FullStack Engineer specializing in Angular, React, and TypeScript to lead the development of our complex, data-driven applications. This role is crucial for designing, building, and maintaining high-performance, responsive, and accessible user interfaces that interact seamlessly with our Python/FastAPI backend services. The ideal candidate possesses deep expertise in modern React and Angular principles, state management, and robust UI architecture, along with a strong understanding of how to optimize data consumption and user experience. You will drive the evolution of our frontend architecture, mentor junior developers, and play a pivotal role in delivering best-in-class user experiences.

Key Responsibilities

Design, development, and delivery of complex, scalable web applications using Angular, React, and TypeScript, and modern JavaScript.
Design, develop, and maintain high-performance backend microservices using Python and FastAPI, focusing on API design and data processing.
Define and implement clean, high-performance UI architecture, utilizing advanced state management solutions and framework-specific patterns.
Collaborate directly with product and UX/UI design teams to translate wireframes and prototypes into pixel-perfect, accessible, and responsive user interfaces.
Work closely with backend engineers (Python/FastAPI) to define and refine API contracts (GraphQL or REST), ensuring optimal data retrieval and efficient frontend consumption.
Establish and maintain our design system and reusable component libraries to ensure visual consistency and development efficiency across applications.
Proactively identify and address frontend performance bottlenecks, conducting profiling and implementing optimizations for rapid page load times and smooth interactions.
Conduct thorough code reviews focusing on architectural integrity, maintainability, performance, and adherence to frontend best practices.
Implement comprehensive unit, integration, and end-to-end tests (e.g., using Jest, Testing Library, Cypress) to ensure application stability and reliability.
Contribute to the full development lifecycle, including active participation in architectural discussions related to both frontend/backend and cloud deployment (AWS).

TypeScript Mastery: Deep experience writing scalable, type-safe code using TypeScript for large-scale applications across multiple frameworks.

State Management: Proven ability to implement and manage complex global state effectively using tools like Zustand/Redux (for React) and leveraging RxJS/Signals (for Angular).

HTML/CSS/Responsive Design: Mastery of modern CSS, preprocessors (e.g., PostCSS/Sass), and utility frameworks (e.g., Tailwind CSS) to build fully responsive and adaptive UIs.

Testing: Strong experience writing and maintaining unit and integration tests (e.g., Jest, React Testing Library, Karma/Jasmine, Cypress).

Performance Optimization: Demonstrated ability to optimize frontend performance, including bundle splitting, lazy loading, reducing rendering costs, and efficient data handling.

API Integration: Expert ability to consume RESTful APIs and/or GraphQL services, including handling caching, authentication, and error propagation on the client side.

Must-Have Skills (FullStack Backend):

Python/FastAPI Development: Strong, demonstrable experience writing and deploying production-ready backend services using Python and the FastAPI framework.
