We are on the lookout for a Senior Data Engineer – Agentic AI to join the Vendor Data team on our journey to always deliver amazing experiences.

Our Vendor Data Team is building the data backbone powering intelligent, self-improving AI systems. As a Senior Data Engineer - Agentic AI, you’ll go beyond traditional ETL and pipelines into autonomous data orchestration. You will design the data interfaces that let AI reason, act, and improve: real-time data flows that fuel agent behavior, tools that enable AI-driven automation, and monitoring systems that ensure quality at scale. Your work won’t sit in dashboards — it will ship into core AI-native products.

Our Agentic AI team is redefining what data engineering means in the age of LLMs — enabling systems that access, evaluate, transform, and learn from data on their own. We treat LLMs as collaborators, not endpoints. Here, data infrastructure becomes a living system: dynamic retrieval, data-aware decision-making, and continuous evolution powered by feedback loops.

If you’re ready to build the data layer for AI that builds AI — this is your playground.

Key Responsibilities

• Architect scalable data pipelines and retrieval systems enabling agentic reasoning and tool usage

• Build and operationalize RAG data flows — ingest, chunking, embeddings, indexing, and vector search optimization

• Develop APIs and data services that allow AI agents to interact with structured/unstructured vendor data in real time

• Monitor data quality, drift, and agent performance using automated evaluation and simulation agents

• Implement validation, observability, and governance to ensure safe, reliable AI behaviors

• Partner with AI and product engineering teams to deliver production-ready intelligence features

• 2+ years building production data systems in applied ML/AI environments

• Strong Python engineering skills — experience with LLM/RAG frameworks (e.g., LangChain, LlamaIndex, Haystack)

• Hands-on experience with vector databases (Pinecone, Weaviate, FAISS) and embedding pipelines

• Clear ownership mindset — you unblock yourself, navigate ambiguity, and deliver outcomes

• Bias toward action: ship fast, iterate responsibly, measure impact

• Pragmatic engineering: working, observable systems > perfect architectures

Nice to have:

• Familiarity with open-source model ecosystems (LLaMA, Mistral, Mixtral) or inference infra

• Experience with safety: prompt injection defense, output validation, agent guardrails

• Designed agent test harnesses or synthetic data systems for feedback loops

• Experience shipping AI-powered features in real-world data platforms, apps, or products
