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
- 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
