Senior Data Scientist (Agentic AI Platform)

What you will do

We are hiring a Senior Data Scientist to play a key role in building our Agentic 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.

How you will do it

• Design, build, and productionize multi-agent systems — including planning, tool calling / function calling, memory, and orchestration — using frameworks such as LangGraph, AutoGen, CrewAI, or Semantic Kernel.
• Develop RAG 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 via tool/function calling and Model Context Protocol (MCP) or similar connector patterns.
• Build and maintain LLM evaluation frameworks for agentic workflows — task-completion metrics, hallucination detection, trajectory analysis, LLM-as-judge pipelines, and A/B testing.
• Implement guardrails, 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) on Azure OpenAI / Azure AI Foundry.
• Design, build, and evaluate classical ML models (classification, regression, forecasting, NLP) where they complement agentic workflows.
• Own LLMOps/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 across Azure 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.

What we look for

Required

• professional experience in data science / ML, with building LLM or GenAI applications in production.
• Hands-on experience with agentic frameworks LangChain or LangGraph.
• Strong understanding of LLM application patterns including prompt engineering
• Expert-level Python (pandas, NumPy, scikit-learn, async programming, API development with FastAPI).
• Experience with vector databases and embeddings (Azure AI Search, Pinecone, Weaviate, Qdrant, FAISS, or pgvector).
• Strong SQL skills and experience working with large-scale data.

What We Offer

• Competitive salary and performance-based incentives.
• Opportunity to architect a greenfield agentic AI platform from the ground up.
• Azure and AI certification sponsorship plus a continuous learning budget.
• Technical leadership pathway and mentorship opportunities.
• Access to cutting-edge GenAI tooling, compute, and cross-domain AI projects.
• Flexible hybrid working model and collaborative culture.
