The opportunity:

Voice is how most people will first reach our new AI assistant. They will pick up the phone, open a mobile app, or tap a voice button, and within seconds expect a real conversation that understands them, their home, and their problem.

As Senior Voice Engineer, you will own that experience end-to-end - from the frontend UI decisions, through the realtime backend, into the agent that actually solves the problem. You will build a voice stack that feels human, runs at consumer scale, and bridges seamlessly into visual and chat channels when the conversation needs to evolve.

Key Responsibilities:

Own the Voice Channel End-to-End

• Architect and build the realtime voice pipeline: STT, TTS, turn-taking, VAD, barge-in, latency tuning.
• Integrate with telephony, mobile SDKs, and messaging channels (WhatsApp, iMessage, in-app voice).
• Design seamless multi-modal handoffs - from voice into camera-based visual sessions and back.

Full-Stack Delivery

• Ship the mobile and web frontends that capture and render the voice experience.
• Build the backend services that drive realtime audio, session state, and integration with our agent platform.
• Make hard calls on protocols, codecs, streaming strategies, and provider trade-offs.

Make It Feel Human

• Obsess over latency, prosody, interruption handling, and recovery from misrecognition.
• Build instrumentation that surfaces voice quality issues before users complain.
• Partner with AI engineers to make sure the agent behind the voice is actually conversational, not transactional.

Set the Bar

• Define the team’s standards for realtime systems, audio quality, and observability.
• Mentor engineers across frontend and backend on voice-first thinking.

Qualifications:

• Senior-level experience building voice-based products in the conversational agent space.
• Strong background across both frontend (mobile and/or web) and backend.
• Hands-on experience with realtime audio systems - STT/TTS providers, streaming, telephony, or equivalent stacks.
• Solid grasp of conversational design pitfalls and how to engineer around them.
• B.Sc. or higher in Computer Science or a related field.

Advantage

• Track record on large-scale production systems.
• Experience with AWS or other major cloud platforms.
• Background with LLM-driven agents, MCP/A2A, or multi-agent orchestration.
