  • Define and enforce security best practices, authentication, and authorization (OAuth2, JWT).
  • Establish standards for structured logging, monitoring, and distributed tracing.
  • Drive cloud-native deployments and ensure systems scale seamlessly.
  • Mentor mid-level engineers, lead architecture discussions, and set engineering standards.
  • Collaborate across product, data, and infrastructure teams to align backend capabilities with business needs.

  • Authentication & authorization (OAuth2, JWT)
  • Logging, monitoring, and tracing (ELK, Prometheus, Grafana, OpenTelemetry)
  • Proven experience leading technical discussions and mentoring developers

Preferred Skills (Nice-to-Haves)

  • Exposure to MCP, A2A is a big plus.
  • Experience with LlamaIndex Workflow and workflow tracing
  • AWS cloud services (EC2, Lambda, S3, API Gateway)
  • Kubernetes orchestration (EKS preferred)
  • CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI)
  • Infrastructure-as-Code (Terraform, CloudFormation)
  • Messaging systems (Kafka, RabbitMQ, AWS SNS/SQS)
