About Us

We’re building Voice AI Agents — powering real conversations for industries like real estate, airlines, insurance, and more. Imagine replacing the frustration of endless call center waits with instant, human-like AI voices that book appointments, qualify leads, and close deals.

We’re trusted by enterprise partners in UAE, Singapore, and Japan — and we’re just getting started.

Why This Role?

This is not a “job.” This is a founding team seat. You’ll own the core tech that shapes how millions of people experience AI conversations. If you’ve ever wanted to build the voice of a global startup from zero to scale, this is it.

What You’ll Do

  • Design and ship production-ready voice AI agents (speech-to-speech or STT-LLM-TTS, low-latency pipelines, integrations with SIP/telephony).
  • Architect and optimize real-time systems using tools like LiveKit, Asterisk/Kamailio, Twilio, or WebRTC.
  • Work on LLM orchestration, prompt engineering, and multi-agent flows.
  • Balance hack-fast prototyping with scalable engineering practices.
  • Collaborate directly with founders, enterprise customers, and early design partners.
  • Shape the engineering culture — from code reviews to hiring standards.

What We’re Looking For

  • Strong background in real-time audio, speech, or ML systems.
  • Hands-on with Python/Go/Node, cloud infra (AWS/GCP), and APIs.
  • Experience (or excitement) with telephony/SIP and LLM APIs.
  • Someone who thrives in chaos and speed — you’ll wear many hats.
  • A builder who cares about impact more than job titles.

Nice to Have

  • Startup experience (ideally seed/Series A stage).
  • Knowledge of speech synthesis (TTS), ASR, or RAG pipelines.
  • Curiosity about multilingual voice AI (Arabic, Japanese, etc.).

What You’ll Get

  • Founding Engineer equity + competitive salary.
  • Freedom to experiment with cutting-edge tech.
  • A global launchpad (we’re scaling across Dubai, Singapore, Japan, US).
  • The thrill (and scars) of building something truly new.
OneInbox.ai is an equal opportunity employer.
