Frontend Integration

• Collaborate with frontend developers to integrate UI components using Angular, React, or Vue into back-end services.

System Reliability & Observability

• Implement basic logging, monitoring, and alerting (e.g., CloudWatch, ELK, Prometheus/Grafana).
• Support troubleshooting efforts and participate in resolving production issues.

Required Qualifications

• 9+ years of hands-on software engineering experience.
• Proficiency in Java (Java 8+), with a strong understanding of OOP principles.
