## About the role

As a Forward Deployed QA Engineer, you will occupy a critical, high-impact role dedicated to ensuring the reliability, stability, and quality of our core conversational AI product, Sage, across diverse client workflows. This role bridges the gap between Quality Assurance, AI Engineering, and Production Operations.

- LLM & Generative AI Expertise: Hands-on experience or deep technical familiarity with troubleshooting LLM behaviors, diagnosing hallucinations, managing latency, and using LLM call-tracing tools
- Technical & Logging Proficiency: Ability to comfortably write SQL queries (specifically PostgreSQL) to pull data logs and navigate cloud infrastructure logs (such as GCP) to perform rapid root-cause analysis
- Voice & Conversational AI Domain Knowledge: Foundational understanding of Speech-to-Speech pipelines, including Automatic Speech Recognition (ASR), audio-to-text workflows, and core knowledge base integrations
- Telephony Foundations: Basic familiarity with enterprise telephony routing, call management mechanics (warm/blind transfers), and voicemail detection systems
- Client-Facing Capability: Strong communication skills and the professional agility required to manage UAT timelines, coordinate with client stakeholders, and support rapid production deployments
