Fullstack Developer - .NET​/Angular

We are seeking a Full-Stack Engineer to drive the development of our client's high-performance, data-dense structured finance credit surveillance applications. In this role, you will work across a cutting-edge hybrid stack: architecting a modern Type Script monorepo (Angular 17+), implementing secure NestJS BFF (Backend-for-Frontend) gateways, and designing scalable, high-performance microservices using .NET 10 / .NET Core. You will be responsible for end-to-end feature ownership, from responsive, reactive user interfaces to highly secure, containerized backend services.

Core Responsibilities

• Full-Stack Development: Build and maintain high-performance features across our entire stack, utilizing Angular 17+ on the frontend, NestJS for BFF orchestration, and .NET 10 / .NET Core for core backend APIs.
• BFF & Gateway Architecture: Maintain a full-stack Type Script monorepo using NestJS as a secure gateway to manage request-scoped token propagation, aggregate data, and interface with upstream REST/GraphQL APIs.
• High-Density UI Engineering: Architect complex, reactive UI modules using container/presenter patterns, lazy loading, route resolvers, and OnPush change detection (including Angular Signals).
• Robust API Design: Design, test, and integrate highly scalable and secure RESTful APIs using .NET 10 / .NET Core and NestJS, adhering to clean REST design patterns (CQRS, API Gateway, etc.).
• Enterprise Security: Implement robust authentication and authorization utilizing OAuth2/OIDC protocols (e.g., Okta), securing both client-side HTTP requests and server-side endpoints.
• Quality & CI/CD Pipeline Management: Champion code quality, security, and automation by maintaining CI/CD pipelines (Jenkins), configuring static code analysis (Sonar Qube), and writing rigorous unit and E2E tests.

• 8+ years of progressive experience in software design and development as a Senior Individual Contributor (IC).

• Angular 17+ & Type Script: Deep, hands-on experience building enterprise Angular applications, utilizing RxJS, Signals, reactive forms with complex validation, and custom UI components.
• Data-Dense UIs: Experience building complex data structures, dynamic validation systems, and integrating specialized grid components (e.g., Handsontable).

• Modern .NET Ecosystem: Expert command of .NET 10 / .NET Core, OOP concepts, SOLID principles, and clean architectural design patterns in C#.
• Node.js / NestJS: Proven experience building enterprise-grade middleware, API gateways, or BFFs using NestJS and Type Script.
• Security & Identity: Strong understanding of OAuth2 flows, secure token propagation (Bearer tokens), and route/endpoint protection.

• Testing Automation: Hands-on testing experience using Karma/Chrome Headless (Angular UI) and Jest/Supertest (API testing).
• Static Code Analysis: Experience using Sonar Qube to monitor code quality, coverage, and security vulnerabilities.
• API Testing: Proficient with Postman for API design, testing, and documentation.

• CI/CD & Source Control: Proficient with Git (branching, merging, Husky pre-commit hooks) and building automated pipelines in Jenkins or Git Hub Actions.
• Containerization: Familiarity deploying and running applications within containerized environments (Kubernetes, AWS EKS).
