The Opportunity

We have just launched Hearth AI Receptionist—an LLM-powered call-handling agent that answers the phone 24/7, books jobs, and syncs every detail back to our CRM. To keep raising the bot’s containment rate, accuracy, and customer delight, we need a detail-obsessed AI Quality Assurance Specialist who will:

• Audit real customer calls and transcripts every day.
• Surface bugs, mis-routes, hallucinations, and UX friction the moment they appear.
• Translate raw call data into crisp product insights and prioritized fixes for our engineers and PMs.
• Own the feedback loop that makes our conversational AI smarter week after week.

What You’ll Do

• Review & annotate calls – Score 150–200 calls/week against a rubric (intent detection, booking accuracy, brand tone, compliance).
  
  
• Write clear tickets – Reproduce issues with call IDs, transcripts, and suggested prompts or flow tweaks.
  
  
• Curate training data – Flag high-quality examples and edge cases for fine-tuning our LLM and speech models.
  
  
• Partner cross-functionally – Present weekly findings to Product, Data Science, and Customer Success; join sprint retros to ensure fixes land.

Who You Are

• 1-2+ years in conversation-AI QA, CX analytics, or contact-center QA.
  
  
• Comfortable with GenAI concepts (LLMs, prompt engineering, speech-to-text).
  
  
• Impeccable attention to detail—hear the nuance in a contractor’s accent and spot a mis-tagged intent.
  
  
• Storyteller who can turn messy call logs into a one-page executive summary.
• Bonus: experience in home-services, SaaS, or voice UX design.

Benefits

• Mission-driven, values-based culture.
• Competitive pay.
• Unmatched opportunities to learn and develop; front-row seat at a fast-growing tech startup
