Job Summary- We are looking for an experienced Agentic AI Developer to design, build, and deploy intelligent autonomous agent systems using Python. You will be responsible for architecting multi-agent workflows, integrating LLMs with real-world tools and data sources, and building the orchestration and reasoning layers that power self-directed AI pipelines. This role sits at the intersection of AI engineering, backend development, and system design.

Responsibilities:Agent Design & Orchestration Design and develop autonomous and semi-autonomous AI agents capable of multi-step reasoning, planning, and decision-making Build multi-agent systems with defined roles, inter-agent communication, and collaborative task execution Implement agent orchestration frameworks (LangGraph, AutoGen, CrewAI, or custom-built) for workflow coordination Define and manage agent memory layers - short-term (context window), long-term (vector stores), and episodic memory Develop tool-use and function-calling pipelines enabling agents to interact with APIs, databases, and external services.

LLM Integration & Prompt Engineering Integrate and fine-tune interactions with LLM providers (OpenAI, Anthropic, Mistral, open-source models via HuggingFace) Design robust prompt templates, system instructions, and chain-of-thought strategies for reliable agent behavior Implement RAG (Retrieval-Augmented Generation) pipelines connecting agents to structured and unstructured knowledge bases Manage LLM output validation, structured output parsing, and fallback/retry logic.

Backend Services & API Layer Build FastAPI-based microservices to expose agent capabilities as REST/streaming APIs Develop event-driven agent triggers using message queues (Redis Streams, Kafka, RabbitMQ) Design agent state management and session persistence using PostgreSQL / Redis Implement task queuing, scheduling, and async execution for long-running agent workflows.

Tool & Data Integration Build and register custom agent tools for file processing, web search, SQL querying, SFTP operations, and third-party API calls Integrate agents with structured data sources (PostgreSQL, data lakes) and unstructured sources (PDFs, Excel, emails) Connect agents to vector databases (Pinecone, Weaviate, pgvector, ChromaDB) for semantic retrieval Enable agents to interact with external systems via MCP (Model Context Protocol) or custom tool registries.

Guardrails, Safety & Reliability Implement guardrails and output validators to ensure agent responses meet business and compliance requirements Build human-in-the-loop (HITL) checkpoints for critical decision nodes within agent workflows Design agent sandboxing and execution boundaries to prevent unintended actions Develop comprehensive error handling, retry strategies, and graceful degradation patterns for agent failures.

Observability & Evaluation Instrument agents with end-to-end tracing (LangSmith, Arize, custom logging) across reasoning steps and tool calls Build evaluation pipelines to measure agent accuracy, latency, tool-use correctness, and goal completion rates Define and monitor KPIs for agent performance - task success rate, hallucination rate, escalation frequency Maintain audit logs of agent decisions, tool invocations, and LLM interactions for debugging and compliance.

Mandatory skill sets: Programming Python (advanced) - async programming, OOP, design patterns Agent Frameworks LangChain, LangGraph, AutoGen, CrewAI, or equivalent LLM APIs OpenAI API, Anthropic Claude, HuggingFace Transformers API Development FastAPI, REST, Streaming APIs (SSE / WebSockets) Prompt Engineering CoT, ReAct, structured outputs, function calling Data Handling Pandas, structured/unstructured data parsing Messaging & Events Redis, Kafka, or RabbitMQ for event-driven agent triggers Databases PostgreSQL for state/session management Observability Logging, tracing (LangSmith / OpenTelemetry), metrics.

Preferred skill sets: Experience with fine-tuning or RLHF pipelines for domain-specific LLMs Familiarity with Model Context Protocol (MCP) for standardized tool integration Knowledge of open-source LLM deployment (Ollama, vLLM, LiteLLM) Exposure to Kubernetes-based microservice deployment for agent services Background in data engineering or ingestion platforms complementing agent data access Understanding of AI safety principles, responsible AI, and model risk management Experience with browser-use or computer-use agents for UI automation tasks.
