Agentic AI Developer

We're hiring an Agentic AI Developer to build production-grade AI calling agents — voice-first autonomous agents that make and receive phone calls, hold natural conversations, and complete real tasks end-to-end.

This is a hands-on role for someone who has already shipped calling agents to real users and knows the difference between a demo and a system that handles thousands of calls without breaking.

If you've built voice agents on Vapi, Retell AI, Bland AI, Synthflow, or LiveKit, or scripted custom flows using Twilio, Deepgram, ElevenLabs, and an LLM, we want to talk.

What You'll Do
  • Build AI calling agents (inbound and outbound) for real use cases — booking, lead qualification, support, follow-ups
  • Design conversation flows, reasoning loops, tool use, and human handoff logic
  • Integrate agents with CRMs, calendars, databases, and third-party APIs
  • Optimize for the three things that matter in voice: latency, accuracy, and natural conversation
  • Handle real-world challenges — interruptions, background noise, accents, silence, call transfers
  • Monitor, debug, and continuously improve agents in production
What You Must Have
  • Proven experience building calling agents — via scripting (Python/Node.js) on telephony APIs, or using platforms like Vapi, Retell, Bland, or Synthflow
  • Hands-on work with LLMs (Claude, GPT, Gemini) — prompt engineering, tool calling, context management
  • Strong grasp of the voice AI stack: STT (Deepgram, AssemblyAI), TTS (ElevenLabs, Cartesia), telephony (Twilio, Plivo)
  • Solid Python or Node.js skills
  • Understanding of latency optimization — you know why 1.5s response time kills a call, and how to get it under 800ms
  • Ability to design flows that handle real human messiness: interruptions, off-topic chatter, unclear requests
Nice to Have
  • Experience with LangGraph, CrewAI, or AutoGen
  • Familiarity with MCP for tool integration
  • Exposure to RAG and vector databases
  • Compliance awareness — TCPA, HIPAA, or similar
  • Domain experience in healthcare, fintech, or real estate
