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 + 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
