Contract

Migration exp is mandatory

You will be part of an agile squad dedicated to the “Feature-First” modernization of our banking platform. Your goal is to take existing business logic—often locked in legacy Java, .NET, or LAMP environments—and migrate it into a modern, Cloud-Native architecture. You are expected to be an early adopter of AI-assisted development (GitHub Copilot/Cursor) to accelerate delivery whilemaintainingthe rigorous precision required for financial transactions.

Key Responsibilities

• Feature Evolution: Enhance existing banking applications by refactoring legacy code into modern, maintainable patterns (e.g., transitioning from a monolith to a modularized service).
• AI-First Development:UtilizeGitHub Copilot, Cursor, or similar LLM tools for 80% of your boilerplate, unit testing, and documentation. You should be able to “vibecode”—iterating quickly with AI to find the best architectural path.
• Full Stack Implementation: Develop andmaintainend-to-end features, from UI components (React/Angular) to API logic and database schemas.
  Cloud Integration: Deploy features into AWS/Azure/GCP environments, following established CI/CD pipelines and Infrastructure-as-Code (Terraform) standards.
  Banking Logic Guardrails: Ensure every line of AI-assisted code meets banking security standards (OWASP) and handles financial data with 100% integrity.

Technical Requirements

• Experience:5–8years of professional software engineering.
• Core Stack (One of the following):
  Java: Spring Boot, REST APIs, Microservices.
  .NET: C#, .NET 6/8, Web API.

  LAMP: Modern PHP (8.x), Laravel/Symfony, transitioning to containers.
• Modern Patterns: Familiarity with Cloud-Native principles (Docker, Serverless) and Event-Driven Architecture.
• AI Proficiency:Demonstratedability to prompt and iterate with AI coding assistants to solve complex logic problems.
