- Build and iterate voice agents for call handling, order taking, reservations, support, refunds, collections, and CRM updates using voice AI platforms.
- Design conversational flows with branching logic, robust fallback handling, tool integrations, knowledge bases, and external system connections.
- Integrate agents with Salesforce and other CRMs via APIs to databases and ordering systems.
- Identify and resolve latency issues across model responses, tool calls, voice interactions, and external integrations.
- Avoid fragile implementations based solely on large system prompts; build modular maintainable agent systems.
- Debug agent behavior using logs conversation reviews traces and user feedback to continuously improve performance.
- Document flows integrations limitations and technical decisions clearly for team continuity.
Build and ship AI voice agents that handle calls, take orders, manage reservations, process refunds, run collections, and update CRM systems. You will design conversational flows with branching logic, fallback handling, and tool integrations while working with platforms like ElevenLabs, Vapi, Retell, or OpenAI Realtime. Your work directly impacts customer experience in payment processing and financial services workflows. You own latency optimization, debugging agent behavior through logs and traces, and maintaining modular, documented implementations. This is a hands-on senior role requiring deep platform expertise and fast iteration in a remote LATAM environment.
