Senior GenAI Engineer - Python/LLM

Role : Senior Gen AI Engineer

Candidate must have a minimum 10 years experience of which past 2 years must be in Generative AI.

Key Responsibilities : 1. GenAI Application Development & Deployment :

• Develop scalable, asynchronous microservices using Python (FastAPI) for chatbots, copilots, and agentic workflows.

• Design event-driven architectures to support high concurrency, rate limiting, and real-time responsiveness.

• Implement secure, versioned REST/gRPC APIs.

• Use Pydantic, dependency injection, and modular coding practices for maintainability.

• Proficient in working with databases using ORMs like SQLAlchemy.

• Ensure observability using logging, metrics, tracing, and health checks.

• Create responsive React.js frontends integrated via REST APIs or WebSockets.

• Deploy applications on Cloud Run, GKE, using Docker, Artifact registry, CI/CD pipelines.

2. LLM-Powered Conversational Interfaces :

• Design and build LLM-powered chatbots, voicebots, copilots and other applications using LangChain or custom orchestration frameworks.

• Integrate enterprise-grade LLM APIs (Gemini, OpenAI, Claude) for multi-turn, intelligent interactions.

• Implement user session management and context/state tracking for personalized and continuous conversations.

• Build RAG pipelines with vector databases, knowledge graphs to ground responses with external knowledge and documents.

• Apply advanced prompt engineering (ReAct, Chain-of-Thought with tool calling) for precise and goal-oriented outputs.

• Ensure performance in low-latency, streaming environments using WebSockets, gRPC, and SIP media gateways.

• Perform fine-tuning of open-source LLMs (LLaMA variants) using techniques like SFT, LoRA, for cost-effective domain adaptation.

• Optimize high-speed inference pipelines leveraging multi-GPU clusters (up to 8x H100s) to reduce latency and improve throughput.

3. Multi-Agent Systems & Orchestration :

• Create multi-agent systems & Implement orchestration patterns like supervisor-agent, hierarchical, and networked agents using frameworks like ADK, Pydantic AI and LangGraph.

• Use LangGraph for stateful workflows with memory, conditional branching, retries, and async execution.

• Enable persistent context and long-term memory.

• Monitor behavior, drift, and performance using observability tools.

• Skilled in developing agents with ADK and A2A protocols & experienced in configuring custom and remote MCP servers.
