Senior RAG & knowledge systems engineers in San Jose run roughly $158–$226/hr. 8K–18K senior ML/AI engineers; deep ex-research talent (Big Tech, FAANG, top labs). 5–8 week senior hiring loop; FAANG counter-offer market. Operating timezone: PT (UTC−8).
2026 RAG: pgvector + Postgres for sub-10M docs, Pinecone or Weaviate for >10M, Cohere/Voyage AI/OpenAI for embeddings, Cohere Rerank or BGE for re-ranking, LlamaIndex or LangChain for orchestration, RAGAS or TruLens for evals. Self-hosted: vLLM + LiteLLM proxy. A real RAG engineer can debug a "the model said X" failure to a chunk-retrieval miss vs an embedding-similarity error vs a prompt-template bug. They run evals before every change. RAG without evals is hope-driven engineering — and hope doesn't scale past beta users.
Where San Jose senior RAG & knowledge systems talent comes from: San Jose senior bench is hardware-leaning — Nvidia, AMD, Intel, Cisco, Apple HQ Cupertino, Google QuickPath, Tesla Fremont, plus Stanford + UC Berkeley + UCSC CS programs. ML-on-hardware (CUDA, ONNX, edge inference) talent is genuinely concentrated here. For RAG & knowledge systems specifically, this means buyers can typically tap engineers who have shipped at one of these orgs before — relevant operational depth, not bootcamp graduates.
Our RAG & knowledge systems team delivers a full range of capabilities tailored to San Jose's Hardware & Semiconductors and Enterprise Software sectors:
Ingest, chunk, embed, and index your documents for fast, accurate retrieval with any LLM.
Internal knowledge systems that let employees search across wikis, SOPs, contracts, and Slack history.
Give your customers an AI assistant that answers product questions using your documentation and help center.
Pull data from PDFs, web pages, databases, APIs, Google Drive, Notion, Confluence, and more.
Every answer includes source citations so users can verify and trust the information.
Continuously improve retrieval quality with evaluation frameworks, feedback loops, and reranking.
Each phase ships with written progress notes plus a weekly review call scheduled in your business hours. See our full process →
When choosing a RAG & knowledge systems partner in San Jose, look for a team with production experience in your specific industry. Generic developers miss critical domain nuances that cost you time and money in rework.
