Sr AI Architect

Job Title: Sr AI Architect

Location: Bay area, CA

Duration: FTE

• 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

Required Skills

Experience

• 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

Evaluation & Production Quality

• Automated evaluation pipeline design — test set curation, metric selection, regression detection · Advanced · Must-have
• A/B evaluation methodology for prompt and model changes · Proficient · Must-have
• Latency profiling for LLM call chains — identifying bottlenecks across multi-step pipelines · Proficient · Must-have
• Feedback loop design — user signal collection, signal-to-retrieval-weight integration · Proficient · Must-have
• Production model monitoring — accuracy drift detection, quality degradation alerting · Proficient · Must-have

Development

• Python — ML/AI application development, async programming · Expert · Must-have
• API design for AI services — streaming endpoints, error handling, timeout management · Advanced · Must-have
• Embedding model operations — model selection, batch embedding, index updates · Advanced · Must-have

Nice to Have

• Adaptive learning systems or personalization engine experience
• Knowledge graph integration with RAG
• Multi-agent orchestration patterns 
• ServiceNow API integration
