About Role
The position requires over 5+ years of full-stack Senior Full Stack Engineer experience with strong hands-on skills in React, TypeScript, AngularJS (for legacy support), Ruby on Rails backend development, and .NET backend APIs.
The engineer will contribute to both modern React micro-frontend applications and legacy AngularJS + Ruby on Rails systems, highlighting the need for production-grade coding across frontend and backend layers.
Experience with REST API design and consumption, API testing via Postman, asynchronous applications, state management, debugging, and CI/CD pipelines is essential.
Must be good at independent handling of technical tasks with least supervisor involvement and ability to quickly adapt to changes in requirements.
Experience with legacy stack technologies including AngularJS, Ruby on Rails, and tools such as Postman, Cypress, Jest, and CI/CD pipelines.
Strong experience in in-depth analysis, troubleshooting, and issue resolution.
Excellent communication and presentation skills.
Success in this role means delivering a stable, scalable React micro-frontend platform, maintaining the AngularJS + Rails legacy system, ensuring reliable frontend-backend integration, producing high-quality code, and effectively leveraging AI tools to accelerate development.
Job Duties
Next-Generation Application (Primary Build Focus):The engineer will design and implement features in a React + TypeScript application using Micro-Frontend architecture, focusing on modular, independently deployable frontend domains. Responsibilities include integrating React micro-frontends with .NET backend APIs, implementing scalable state management, routing, and performance optimization strategies, and contributing to architectural decisions for the platform's long-term evolution.
Legacy System Maintenance (AngularJS + Ruby on Rails):Maintaining and enhancing the existing AngularJS application and Ruby on Rails backend is a critical task. This includes writing, modifying, and refactoring backend code, debugging production issues across both layers, implementing feature enhancements and bug fixes, and ensuring system stability, performance, and security. The role requires active hands-on Ruby on Rails coding, not merely API consumption.
Backend API Integration & Validation:The role involves designing and consuming RESTful APIs, integrating frontend applications with Ruby on Rails and .NET services, testing and validating APIs using Postman, debugging API contracts and authentication flows, and ensuring reliable error handling and data consistency across systems.
AI-First Engineering Approach:The engineer is expected to leverage AI-assisted development tools for code generation, refactoring, test creation, debugging, and documentation. This approach aims to improve engineering velocity without compromising quality and to continuously adopt modern AI-enabled development practices.
Quality & DevOps:Responsibilities include writing unit, integration, and end-to-end tests using Cypress and Jest, participating in CI/CD workflows, validating functionality before production releases, and applying secure coding and API consumption best practices.
