• Design and build LLM‑powered applications for internal and/or customer‑facing use cases
• Develop and product ionize RAG pipelines using enterprise data sources, vector databases, and retrieval systems
• Build and optimize AI agents / agentic workflows for task automation, reasoning, and orchestration
• Integrate model providers such as OpenAI, Anthropic, Azure OpenAI, AWS Bedrock
  , and open‑source models where appropriate
• Create robust evaluation frameworks for response quality, factuality, latency, safety, and reliability
• Implement prompt engineering
  , structured outputs, tool calling, and model optimization strategies
• Deploy scalable AI services to cloud environments using modern software engineering and MLOps practices
• Build monitoring, observability, and feedback loops for model and application performance in production
• Establish and maintain guardrails
  , responsible AI practices, and security controls for enterprise AI systems
• Collaborate with product managers, designers, and business stakeholders to identify high‑impact AI opportunities
• Mentor other engineers and contribute to architecture, technical direction, and engineering best practices
