- Familiarity with CI/CD pipelines and embedding automated quality gates.
- Proven ability to use AI-powered development tools (e.g., Claude, GitHub Copilot, ChatGPT) to accelerate the SDLC.
What You Will Do:
- Design, develop, and maintain full-stack web applications using .NET and ReactJS.
- Integrate and champion AI-powered development tools across the SDLC.
- Drive a quality-first development culture: author comprehensive unit, integration, and end-to-end tests.
- Collaborate with product managers, designers, QA engineers, and fellow developers.
- Architect and build microservice-based, event-driven systems.
- Mentor junior engineers on AI tool adoption and full-stack best practices.
