AI summary of the role
Senior Staff Applied AI Engineer owning the zero-to-one build of context retrieval for Databricks agents across SaaS providers.
No longer in the current catalog. Last included 2026-09-09. Check the employer’s posting for availability.
What you’ll do
- Build the full retrieval stack from scratch: query understanding, content understanding and indexing, hybrid retrieval, ranking, and evaluation.
- Retrieve across heterogeneous data — structured (tables, SQL, code, notebooks) and unstructured (docs, wikis, chat, images, video).
- Build search subagents that reason about retrieval: plan multi-hop searches, issue follow-up queries, ground claims, and signal failure.
- Crack query understanding for agents: query rewriting, decomposition, intent classification, entity resolution for multi-turn agentic workflows.
What you’ll bring
- 10+ years software engineering experience building production retrieval, search, or RAG systems at scale.
- Deep IR expertise: lexical retrieval (BM25, Lucene/Elasticsearch/OpenSearch), dense retrieval (FAISS, ScaNN, HNSW), hybrid retrieval, learning-to-rank.
- Hands-on experience with LLM-era retrieval: RAG architectures, query rewriting, cross-encoder re-ranking, long-context strategies, grounding techniques.
- Experience designing agentic systems on top of retrieval: search planners, multi-hop/iterative retrieval, self-reflection, tool-using agents.

P-1549 At Databricks, we are passionate about enabling data teams to solve the world's toughest problems — from making the next mode of transportation a reality to accelerating the development of medical breakthroughs. We do this by building and running the world's best data and AI infrastructure platform so our customers can use deep data insights to improve their business. The Mission Databricks agents are only as good as the context they can retrieve. Whether an agent is answering a question about last quarter's revenue, debugging a failing job, generating SQL against a 10,000-table lakehouse, or summarizing a Wiki page, its quality is bounded by what it can find — and how well it understands what it finds. We are hiring a Senior Staff Applied AI Engineer to own context retrieval for Databricks agents across SaaS providers. This is a zero-to-one role with two deeply connected charters: Build the retrieval stack — query understanding, content understanding, ranking, retrieval, and evaluation — across the Enterprise SaaS data stored across multiple systems. Build the search subagents that sit on top of that stack and reason about what context is needed, how to retrieve it, and whether the right thing actually came back — closing the loop between an agent's intent and the substrate that serves it. If you have deep Information Retrieval wisdom, have shipped retrieval syst [... source excerpt omitted ...] ems for RAG and agentic workloads, and want to build the substrate — and the agents on top of it — that make every Databricks agent measurably smarter, this role is for you. What You Will Do Build the full retrieval stack from scratch. Own the end-to-end system: query understanding, content understanding and indexing, hybrid retrieval, ranking, and evaluation. Make the architectural calls that will define how Databricks agents access context for years to come. Retrieve across heterogeneous data — structured and unstructured. Index and rank across structured assets (tables, columns, SQL queries, dashboards, code, notebooks, jobs) and unstructured content (docs, wikis, tickets, [... source excerpt omitted ...] content understanding at scale. Build the pipelines that extract structure, entities, embeddings, summaries, and metadata from every supported asset type — and keep them fresh as customer data evolves. Build search subagents that reason about retrieval. Design the agentic layer that decides what context is needed, which sources to query, how to decompose and route the search, and — critically — whether the retrieved content is actually sufficient to answer the question. These subagents will plan multi-hop searches, issue follow-up queries when results are weak, ground claims against retrieved evidence, and hand back high-confidence context (or signal failure) to upstream agents
