Technical Leadership & System Architecture

• Lead the architecture and development of LLM-driven applications, AI agents, and RAG-based systems.
• Provide technical guidance, conduct code reviews, and mentor junior team members.
• Drive best practices in Python backend engineering, API development, and AI system design.

Backend Engineering (Python)

• Build and maintain backend services using FastAPI or Flask.
• Develop scalable API endpoints for AI applications, embeddings, and retrieval systems.
• Ensure backend code quality, modularity, performance, and maintainability.

LLMs, RAG, and AI Agent Development

• Build AI applications using: LangChain, LangGraph, Semantic Kernel, Haystack, LlamaIndex, AutoGen

• Develop autonomous or semi-autonomous AI agents with tool calling and workflow graphs.
• Implement Retrieval-Augmented Generation (RAG), embedding pipelines, chunking strategies, reranking, and grounding techniques.
• Work with OpenAI SDK and other LLM providers (Anthropic, Azure OpenAI, Cohere, etc.).
• Manage prompt engineering, prompt routing, safety guardrails, and evaluation metrics.


Data & Vector Search Engineering
• Build data pipelines for indexing, embeddings, and retrieval workflows.
• Work with SQL databases (PostgreSQL, MySQL, etc.) for metadata and application storage.
• Work with vector databases such as: Redis, Postgres with pgvector, Elasticsearch, Neo4j, or others.
• Implement and optimize search workflows using FAISS or similar similarity search libraries.


MLOps, Deployment & Observability
• Deploy AI services using Docker, container orchestration, and cloud environments.
• Implement monitoring for AI behavior, performance, error rates, and retrieval accuracy.
• Set up CI/CD pipelines for backend and AI components.
• Optimize inference cost, latency, and reliability.


Cross-Functional Collaboration
• Collaborate with product, data engineering, and business teams to understand requirements.
• Translate business problems into scalable AI architectures and deliver practical solutions.
• Communicate technical decisions, trade-offs, and progress to stakeholders.

Requirements:
• Bachelor's/Master's degree in Computer Science, AI/ML, Data Science, or related fields.
