Senior AI Engineer, Agentic and RAG Systems

We are seeking a hands-on Senior AI Engineer who designs, builds, and operates production GenAI systems – agentic workflows, RAG pipelines, and LLM-backed services with real users and real SLAs. This is an engineering role, not a research role. The bar is reliability, latency, cost, observability, and safe deployment at scale, with end-to-end ownership from architecture through on-call. Typical workloads include enterprise knowledge platforms, conversational analytics, agentic automation, and LLM-augmented data products.

Responsibilities

• Design agent orchestration (graph/state, conditional routing, tool calling, memory, checkpointing) in LangGraph / LangChain or equivalent
• Build production RAG end-to-end: chunking, embeddings, vector stores, hybrid retrieval, reranking, caching, and grounded synthesis
• Own Python / FastAPI services – async, SSE streaming, session handling, and structured error contracts
• Instrument with tracing and evaluation harnesses (MLflow, OpenTelemetry, or equivalent) for accuracy, cost, and regression
• Ship on Docker + Kubernetes (EKS/AKS/GKE) via CI/CD with test, eval, and canary gates
• Drive LLM cost engineering – model routing, prompt optimization, caching, token accounting, and build-vs-buy decisions
• Apply GenAI safety & governance: hallucination control, prompt-injection defense, PII handling, and HITL where required
• Partner with data engineering on semantic layers and pipelines (PySpark / SQL where applicable)

Requirements

• 5+ years in software engineering, with 2+ years shipping production LLM / agentic systems (not POCs or research)
• Proficiency in Python and FastAPI (async, REST, SSE)
• Production expertise in LangChain and LangGraph (or equivalent serious production experience with LlamaIndex, AutoGen, or MCP stacks)
• Background in production RAG: embeddings, chunking, and hybrid retrieval with reranking and caching
• Skills in vector databases such as Pinecone, Weaviate, pgvector, OpenSearch, or Databricks Vector Search
• Knowledge of at least one major LLM provider in production – AWS Bedrock (preferred), OpenAI / Azure OpenAI, or Anthropic – with model selection and routing trade-offs
• Competency in Kubernetes and Docker in real production environments (EKS/AKS/GKE)
• Expertise in cloud engineering on AWS
• Familiarity with observability and tracing tools (MLflow, LangSmith, OpenTelemetry), evaluation harnesses, and latency/cost ownership
• Capability to build CI/CD for AI systems (GitHub Actions, Jenkins, or equivalent) with test/eval gates
• Strong written and spoken English (B2 level); able to own design discussions with engineering and business stakeholders independently

Nice to have

• Databricks depth – MLflow (tracking & serving), Vector Search, Unity Catalog / Metric Views, PySpark / SQL
• Experience with LLM fine-tuning – PEFT, LoRA, QLoRA
• Understanding of MCP servers and tool integration
• Qualifications in GenAI governance & FinOps – auditability, prompt-injection hardening, PII, and token cost in regulated environments
• Background in classical ML / DL – NLP, BERT-family, time-series, and CV
