Job description

We are seeking a talented and driven Full-Stack Developer to design, develop, and maintain a high-performance REST API using Python with FastAPI, along with a modern web application built using Angular 19 or later. In this role, you will work on a system that requires fast and efficient data retrieval, as well as a polished and responsive user interface capable of handling large datasets effectively.

Roles and Responsibilities

• Design and develop scalable RESTful APIs using Python and FastAPI, optimized for high-volume, high-performance data operations
• Use GitHub Copilot to scaffold endpoints, generate docstrings, and accelerate boilerplate code creation
• Write maintainable, well-structured TypeScript with strong adherence to Angular 19+ best practices and component architecture including signals, dependency injection, standalone components
• Integrate AG Grid into the UI to display and interact with large datasets efficiently virtual scrolling, filtering, sorting, drill-down or pivoting, etc.
• Implement WebSocket connections for real-time data communication between the API and the UI
• Secure APIs using OAuth2 or JWT authentication and authorization patterns
• Design and optimize queries against Microsoft SQL Server, ensuring efficient data access patterns for large datasets and use AI tools to assist in query analysis and optimization suggestions
• Leverage AI tools to assist with writing clean, maintainable, and well-tested code with strong unit test coverage for example pytest for Python, Jest for Angular
• Manage source code using Git and follow branching and PR best practices via GitHub
• Build and maintain CI CD pipelines using GitHub Actions
• Actively leverage Generative AI tools for example GitHub Copilot to accelerate development, improve code quality, and explore innovative solutions across the entire development lifecycle from design to deployment
• Stay current with evolving AI developer tooling and propose adoption of new capabilities that improve team productivity
• Collaborate with cross-functional teams including BA, QA, and Product Owners
