Tech Lead - Data Science

About the Role

We are hiring a Tech Lead - Data Scientist to play a key role in building ourAgentic AI Platform — a system of autonomous, tool-using AI agents that plan, reason, and execute complex business workflows end-to-end. The ideal candidate combines strong ML fundamentals with hands-on experience in LLM-based application development, agent orchestration frameworks, and Microsoft Azure cloud services. You will architect and ship production-grade agentic solutions, mentor junior team members, and set technical direction for GenAI initiatives across the organization.

Experience -8 to 12 yrs

Key Responsibilities

• Design, build, and productionizemulti-agent systems — including planning, tool calling / function calling, memory, and orchestration — using frameworks such as LangGraph, AutoGen, CrewAI, or Semantic Kernel.

• DevelopRAG pipelines end-to-end: document ingestion, chunking strategies, embeddings, vector search (Azure AI Search / FAISS / pgvector), re-ranking, and grounding for agent knowledge.

• Integrate agents with enterprise systems and APIs viatool/function calling andModel Context Protocol (MCP) or similar connector patterns.

• Build and maintainLLM evaluation frameworks for agentic workflows — task-completion metrics, hallucination detection, trajectory analysis, LLM-as-judge pipelines, and A/B testing.

• Implementguardrails, safety, and governance for agents: prompt-injection defense, content filtering, role-based tool permissions, human-in-the-loop checkpoints, and audit logging.

• Fine-tune and optimize LLMs where needed (LoRA/PEFT, prompt optimization, model routing, latency/cost trade-offs) onAzure OpenAI / Azure AI Foundry.

• Design, build, and evaluate classical ML models (classification, regression, forecasting, NLP) where they complement agentic workflows.

• OwnLLMOps/MLOps for the platform: experiment tracking, prompt versioning, CI/CD, observability and tracing (LangSmith, Azure Monitor, OpenTelemetry), drift monitoring, and retraining strategies.

• Collaborate with data engineers on data quality, availability, and governance acrossAzure Data Lake, Databricks, and Synapse Analytics.

• Translate ambiguous business problems into agentic AI solutions; present architecture decisions and results to senior stakeholders.

• Mentor junior data scientists, lead code/design reviews, and champion engineering best practices.

Required Skills & Qualifications

• Bachelor's or Master's degree in Computer Science, Data Science, Engineering, Mathematics, or a related field.

• 8-10 years of professional experience in data science / ML, withat least 3 years building LLM or GenAI applications in production.

• Hands-on experience withagentic frameworks: LangChain/LangGraph, AutoGen, CrewAI, Semantic Kernel, or equivalent (at least one in production).

• Strong understanding ofLLM application patterns: prompt engineering, function/tool calling, structured outputs, RAG, agent memory, and multi-agent orchestration.

• Expert-levelPython (pandas, NumPy, scikit-learn, async programming, API development with FastAPI).

• Hands-on experience withAzure services: Azure OpenAI / AI Foundry, Azure ML, Azure AI Search, Azure Databricks, Azure Data Factory, or Synapse.

• Experience withvector databases and embeddings (Azure AI Search, Pinecone, Weaviate, Qdrant, FAISS, or pgvector).

• Solid grounding in classical ML: supervised/unsupervised learning, model evaluation, and hyperparameter tuning; experience withTensorFlow or PyTorch.

• StrongSQL skills and experience working with large-scale data.

• ProvenMLOps/LLMOps experience: MLflow, prompt/model versioning, CI/CD (Azure DevOps or GitHub Actions), and production monitoring.

• Ability to evaluate and mitigate LLM-specific risks: hallucination, prompt injection, data leakage, and cost/latency constraints.

Good to Have

• Experience withModel Context Protocol (MCP), OpenAI Assistants/Agents SDK, or Anthropic tool-use APIs.

• Microsoft certifications:AI-102 (Azure AI Engineer),DP-100 (Azure Data Scientist Associate).

• Experience fine-tuning open-source LLMs (Llama, Mistral, Phi) using LoRA/QLoRA and serving via vLLM or Azure ML endpoints.

• Familiarity withobservability/tracing for agents: LangSmith, Langfuse, Arize Phoenix, or OpenTelemetry.

• Knowledge of containerization and deployment:Docker, Kubernetes (AKS), Azure Container Apps.

• Big data experience withApache Spark (PySpark) via Azure Databricks.

• Experience with knowledge graphs, graph RAG, or semantic layers for agent grounding.

• Contributions to open-source GenAI/agentic projects or published technical content.
