We are building a Voice AI product, and the quality of every conversation it has comes down to two things: how well it is instructed and how closely it is monitored. This role sits at the intersection of prompt engineering, quality assurance, and operations. You will write and refine the prompts that shape how our voice agents think and respond, analyze real interactions to identify areas for improvement, and help ensure consistent performance at scale. This role is ideal for someone with excellent language skills, strong analytical thinking, and a keen eye for detail. Prior coding experience is helpful but not mandatory.
Selected intern's day-to-day responsibilities include
Design, write, test, and refine prompts for Voice AI agents, including system prompts, instructions, and dialogue logic.
Build and optimize conversation flows, including fallbacks, error handling, and recovery from misunderstandings.
Test voice interactions for accuracy, naturalness, latency, interruptions, and edge-case scenarios.
Review call transcripts and interaction logs to identify failure patterns and improve prompt performance.
Conduct structured A/B testing of prompts and document findings to optimize conversation quality.
Curate and label datasets while helping build evaluation sets to measure AI performance objectively.
Monitor the live performance of Voice AI agents, identify issues, and support the timely resolution of production problems.
Maintain prompt libraries, operational playbooks, and standard operating procedures (SOPs) to ensure consistency and knowledge sharing.
Manage day-to-day operational tasks, including issue triaging, escalation handling, and incorporating customer feedback into product improvements.
