We're Hiring | Full Stack AI Engineer – Multi-Agent Systems
We are looking for a Full Stack AI Engineer who can own end-to-end feature delivery – from designing agent communication patterns and orchestration logic on the backend, to building intuitive interfaces for configuring, monitoring, and debugging agent workflows. You will work directly with the architect and product owner to translate orchestration concepts (agent-to-agent messaging, tool use, handoffs, memory) into a production-grade system.
This is a hands-on builder role. You will not be writing strategy decks – you will be shipping agents, APIs, and UI.
Location: Pune
Experience: 4–7 Years (1.5+ years in GenAI/AI Agents)
Employment Type: Full-time
Key Responsibilities
Backend & Agent Development
• Design and implement multi-agent workflows using AG2 (AutoGen) and/or LangGraph – including agent roles, conversation patterns, handoffs, and termination conditions.
• Build and maintain FastAPI services that expose orchestration capabilities (agent registration, task submission, run status, streaming responses) to the frontend and external consumers.
• Implement tool/function calling, structured outputs, and memory layers (short-term, long-term, vector-based) for agents.
• Integrate LLM providers (OpenAI, Anthropic, AWS Bedrock, or local models via Ollama) with proper retry, timeout, and cost controls.
• Write clean, testable Python with type hints, pydantic models, and clear separation between orchestration logic and infrastructure.
Frontend Development
• Build React-based interfaces for configuring agents, visualising agent conversations, inspecting tool calls, and debugging runs.
• Implement streaming UI (SSE/WebSockets) to render token-by-token agent responses and intermediate steps.
• Collaborate on UX for workflow builders, run history, and observability dashboards.
System & Production Concerns
• Containerise services with Docker and contribute to CI/CD pipelines.
• Add logging, tracing, and basic evaluation hooks for agent runs (latency, token usage, success rates).
• Participate in code reviews, design discussions, and incremental hardening of the platform.
Must-Have Skills
• Full stack experience (5+ years): strong Python (FastAPI or similar) on the backend AND React on the frontend. Comfortable owning a feature across both layers.
• Hands-on with at least one agent framework: AG2 (AutoGen), LangGraph, LangChain Agents, or CrewAI. Must have actually built and run multi-agent flows, not just read about them.
• LLM application development: prompt design, tool/function calling, structured outputs, handling streaming responses, and basic context management.
• RAG fundamentals: chunking strategies, embeddings, vector stores (pgvector / Qdrant / Weaviate / FAISS), and retrieval evaluation. Bonus for hybrid (sparse + dense) retrieval.
• Database skills: PostgreSQL – schema design, indexing, and writing reasonable queries.
• API & async patterns: REST design, async Python (asyncio), background jobs, and streaming endpoints.
• Version control & collaboration: Git, PR-based workflows, writing clear commit messages and design notes.
Good-to-Have Skills
• Experience with GCS for deploying AI workloads.
• Familiarity with LLMOps – tracing (LangSmith / Langfuse / OpenTelemetry), evaluation frameworks, and prompt versioning.
• Exposure to MCP (Model Context Protocol) or A2A (agent-to-agent) communication standards.
• Experience running local LLMs (Ollama, vLLM) for prototyping or cost-sensitive workloads.
• Knowledge of WebSockets / SSE for real-time UIs.
• Basic understanding of fine-tuning concepts (LoRA / QLoRA) – we are not expecting trainers, just awareness.

This is an SDE II Full Stack Developer role, but mostly backend: around 70% Python and FastAPI and 30% frontend in React or Angular. You'll build and ship real AI applications such as AI agents, LLM-based workflows, and APIs that connect AI models to web products, using SQL and NoSQL databases on the cloud, mainly Google Cloud. It's not research or prototype work. What you build goes live for enterprise clients, so you'll also own performance, security, and monitoring. You'll report to the Lead Engineer and spend some time each day guiding junior engineers. The role is fully on-site in Chennai from Day 1, with hybrid possible later based on performance. The process has 3 technical rounds (1 virtual and 2 on-site) followed by a salary discussion. The panel focuses on practical system design and real projects you've built, so be ready to explain what business problem you solved and the result it delivered. If you've built and shipped AI-powered backend systems with 4–10 years of experience and want ownership in a fast-moving AI company, this is a strong fit.
