Debug, analyze, and resolve customer-reported issues and production defects, including deep troubleshooting across device/OS/network/service layers.

Familiarity with microservices concepts and common integration approaches (API, callbacks/webhooks, message-based patterns).

Experience with SQL and NoSQL databases.

Hands-on experience with containerized environments (Docker); Kubernetes/EKS exposure is a plus.

Familiarity with cloud platforms (AWS preferred).

Proven ability to debug complex issues across Android device, OS, backend services, and network layers.

Familiarity with or interest in AI-assisted development tools to improve productivity, automation, and code quality.
