About the Role

We’re looking for a hands-on engineer to build real-time, voice-enabled autonomous AI agents for next-generation Sales CRM workflows. You’ll combine low-latency voice streaming, stateful multi-agent orchestration, and production-grade backend engineering to ship agents that can hold natural conversations and act inside a CRM.

• Design and tune STT and TTS pipelines for low latency and natural-sounding conversation
• Engineer real-time audio streaming over WebSockets/WebRTC, including VAD, dynamic interruption handling, and turn-taking logic
• Build stateful, multi-agent workflows with tool calling using LangGraph and LangChain
• Integrate multiple LLM providers (OpenAI, Anthropic Claude, Google Gemini)
• Use graph-based architectures, graph databases, and GraphRAG for knowledge retrieval and contextual grounding
• Build and integrate REST APIs, and ship containerized services with tracing and evaluation in place

Required Skills

• Strong Python with robust asynchronous programming (asyncio) and scalable backend design
• Hands-on experience with LiveKit Agents, Pipecat, or equivalent voice agent frameworks
• STT experience: Deepgram, Whisper, AssemblyAI, or equivalent
• TTS experience: ElevenLabs, OpenAI TTS, Azure Speech, or equivalent
• Real-time audio streaming (WebSockets/WebRTC), low-latency pipelines, VAD, interruption handling
• LangGraph and LangChain for stateful orchestration, multi-agent collaboration, and tool calling
• Multi-provider LLM integration (OpenAI, Claude, Gemini)
• Graph databases and GraphRAG
• Observability and tracing (OpenTelemetry, LangSmith), LLM evaluation frameworks, Docker/containerized deployment
