AI Prompt & Agent Developer

OpenCall.ai is a company focused on voice AI technology for multi-location medical groups. They are seeking an AI Prompt & Agent Developer to enhance their voice agents by writing prompts, analyzing data, and improving agent performance through continuous evaluation and iteration.

Responsibilities:

• Write and maintain the prompts that run in production. Intent classification, information extraction, availability negotiation, closing phrases, insurance verification flows, objection handling, edge-case recovery. You own behavior that touches every customer call
• Ship iteratively against real call data. Every morning, you'll listen to failed calls from yesterday. Every afternoon, you'll deploy a fix. Every week, you'll move eval metrics. You’ll be using and helping to develop dashboards, call review tooling, and automated agents to accelerate the work
• Build evaluation harnesses. You'll develop offline eval sets, run automated prompt optimization (we use GEPA-style approaches), and establish the test suites that let us ship changes without breaking live deployments
• Human-in-the-loop onboarding. New customers come online constantly. You'll work with and iterate on our internal AI agents that translate a practice's intake form, their scheduling rules, and their quirks into an agent configuration
• QA and continuous improvement. You'll simulate real-world customer scenarios, measure outcomes, and monitor production agent performance so you can catch drift early and fix it fast
