AI - Sr Application Engineer - Bay area, CA - Fulltime

Job Title: AI – Sr. Application Engineer

Location: Bay area, CA

Duration: Fulltime

Number of Roles: 5

Job Description:

• Will work on the intelligence layer for multiple programs — owns all model quality, RAG accuracy, prompt engineering, and AI safety across applications 
• Socratic tutor persona, adaptive learning recommendation engine, multi-modal AI (text and voice), RAG evaluation framework, and feedback loop into retrieval
• 6-LLM call chain orchestration (NeMoGuardrails → intent classification → query rewriting → RAG → synthesis), and compatibility check logic
• Production-grade AI quality from launch — this is not a research or prototyping role; accuracy thresholds, latency requirements, and safety guardrails must pass InfoSec adversarial testing before Release 1

Experience

• Total IT 10+ Years
• 4–7 years of software engineering with at least 2 years focused on LLM application development in production — not research, not demos, not internal tools with 10 users
• Has shipped an LLM-powered feature or product to production where real users depend on the accuracy and the engineer owns the quality metrics
• Has owned an AI safety or guardrails implementation for a customer-facing product — not just added an off-the-shelf filter; designed and tested the safety layer
• Has built RAG evaluation pipelines and used them to make go/no-go release decisions — accuracy gating is part of the workflow.
• Has profiled and optimized a multi-step LLM call chain for latency
