• Model complex business domains and design data structures that support change over time
• Define clear service boundaries, API contracts, and integration patterns
• Contribute to shared backend architecture, standards, and reusable patterns
• Evaluate trade-offs between performance, consistency, scalability, and delivery speed

Integration & Event-Driven Solutions

• Design and implement RESTful APIs with proper versioning, error handling, and contract validation
• Implement asynchronous messaging and event-driven patterns for reliable and decoupled integrations
• Design events that reflect meaningful business state changes
• Support both synchronous and asynchronous service communication

Software Quality & Testing

• Write clean, testable, and maintainable code
• Implement unit, integration, and contract testing
• Build fast, reliable automated regression test suites
• Contribute to test data strategies and quality standards

DevOps, Cloud & Observability

• Work with automated CI/CD pipelines for build, test, security scanning, deployment, and rollback
• Implement infrastructure-as-code and environment automation where applicable
• Deploy and operate services in a cloud environment (Azure or similar)
• Design and maintain logging, metrics, tracing, dashboards, and alerting
• Perform root cause analysis and implement long-term fixes for production issues

Collaboration & Delivery

• Work in a distributed Agile/Scrum team across multiple time zones
• Analyze requirements, identify risks and dependencies, and propose technical solutions
• Participate in architecture and code reviews
• Maintain clear and accurate technical documentation
• Contribute to engineering process and tooling improvements

AI & Developer Productivity

• Use AI-assisted development tools responsibly for code generation, refactoring, testing, and documentation
• Help define effective team practices for adopting AI in the development lifecycle
