AI Sr. Application Engineer

Experience

• Total IT 15 + 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
