• Familiarity with frameworks such as LangChain, LlamaIndex, or Semantic Kernel.
• Experience implementing secure and compliant AI pipelines, with understanding of prompt injection defenses and data privacy principles.
• Proficiency with cloud-based AI infrastructure, preferably Azure AI Services, Azure DataBricks, and Azure OpenAI Service.
• Excellent problem-solving, communication, and collaboration skills.
• Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent professional experience.

Preferred Qualifications

• Experience fine-tuning or customizing LLMs for enterprise applications.
• Familiarity with MLflow, MLOps practices, and CI/CD pipelines for model deployment.
• Knowledge of medallion data architecture and Delta Lake for AI-ready data management.
• Experience with real-time data streaming systems (e.g., Kafka, Event Hubs).
• Contributions to open-source AI frameworks or enterprise-level AI integrations.
