Senior Data Engineer - Agentic AI

Requirements

• 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

What you'll be doing

• 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
