Node.js and Voice AI Agent developer

We are looking for a highly skilled Node.js Developer with a focus on Voice AI to build and orchestrate intelligent, low-latency autonomous agents using leading platforms (e.g., Vapi, Retell, LiveKit). You will be responsible for the "logic and integration" layer - connecting these voice platforms with sophisticated backend systems to create seamless, human-like conversational experiences that solve real-world business problems.  

Main Responsibilities

• Platform Orchestration & Backend Integration: Design, implement and maintain Node.js backends that integrate seamlessly with Voice AI platforms to manage call flows, webhooks, and real-time data exchange between the voice agent and external business systems.  
• Performance & Interaction Tuning: Optimize end-to-end conversation performance by fine-tuning platform-specific settings (such as model selection and provider configurations) and ensuring that backend API responses are optimized for ultra-low latency to maintain a natural flow.  
• Agent Intelligence & Tool-Calling: Implement complex reasoning and autonomous task execution by developing sophisticated prompt engineering strategies and robust server-side tools that allow agents to interact with databases and third-party APIs in real-time
• Integration: Connect AI agents to existing business software, databases, and third-party services via API-native configurations.
• Monitoring & Testing: Build automated test suites to identify hallucination risks.

Position Requirements

• Node.js Mastery: experience with Node.js, TypeScript, and asynchronous programming.
• Voice AI Expertise: proven experience with voice-first ecosystems like Vapi, Telnyx, Retell, LiveKit
• AI Knowledge: deep understanding of Large Language Models (LLMs) and prompt engineering.
• Infrastructure: experience with WebSocket communication, real-time data streaming, and cloud platforms (AWS, Google Cloud).
• Problem Solving: experience debugging Voice Agent issues and optimizing server-side performance for low latency responses.

What we offer

• Competitive compensation based on your skills and experience.
• Flexible working hours and a remote-first culture built on trust and accountability.
• A supportive environment that encourages learning, experimentation, and professional growth.
