• Design prompt systems, model instructions, retrieval flows, tool calls, conversation memory, and structured output schemas.
• Integrate cloud and local LLM APIs, OpenAI-compatible endpoints, embedding models, vision models, and rerankers.
• Create reusable AI workflow patterns for summarization, extraction, classification, reasoning support, report generation, and human review.
• Implement guardrails for reliability, source attribution, schema validation,fallback behaviour, and user confirmation before high-impact actions.
• Build evaluation sets and scoring methods to measure answer quality,hallucination risk, retrieval relevance, latency, and cost.
• Work with business users to turn vague automation ideas into specific AI product flows with measurable acceptance criteria.

Required Qualifications
• Strong Python or TypeScript development skills.
• Hands-on experience building with LLM APIs, chat completions, structuredoutputs, function/tool calling, or agent workflows.
• Practical understanding of prompt design, context windows, token limits, retrieval augmentation, and output validation.
• Ability to ship usable applications, not only prototypes or notebooks.
• Comfortable debugging model behaviour and separating application bugs from model limitations.

Nice-to-Have Experience
• Experience with LangChain, LlamaIndex, Semantic Kernel, instructor, Pydantic, or similar frameworks.
• Experience with multimodal applications involving images, OCR, audio, or document understanding.
