Develop and support event-driven architectures using Kafka and Azure Event Hubs.
Integrate data from diverse sources, including SQL Server, data warehouses, and streaming platforms.
Create and deploy AI-enhanced services using Azure OpenAI, LLM frameworks (e.g., LangChain, Semantic Kernel), or Databricks ML.
Collaborate with engineering, analytics, and DevOps teams to deliver production-grade, intelligent solutions.
Ensure high performance, security, and reliability across API and data systems in the cloud.

Proficiency with SQL Server for data modeling, querying, and optimization.
Familiarity with Apache Kafka or Azure equivalents.
Experience integrating or experimenting with AI/ML solutions such as Azure OpenAI, MLflow, or prompt engineering.
Understanding of CI/CD, Docker, and infrastructure-as-code (Terraform/Bicep).
Awareness of security best practices, including OAuth2, managed identities, and role-based access control (RBAC).

Preferred Skills

Experience with LLM orchestration frameworks (e.g., LangChain, Semantic Kernel, Prompt Flow).
Knowledge of Azure API Management, Logic Apps, or Service Bus.
Familiarity with dbt, Airflow, or similar orchestration tools.
Understanding of Responsible AI principles and AI governance in enterprise settings.
