Principal Engineer — Voice AI Platform

CONFIDENTIAL SEARCH

Ref: HN-2609-PEVAI

Build the future of conversations. Lead Voice AI that millions rely on.

HiredNext is managing a confidential search for a profitable, established enterprise SaaS company building the next generation of its real-time Voice AI platform.

This is a Principal-level individual contributor role for someone who is still deeply hands-on with architecture, production code, debugging and platform performance. The mandate is broad and technically demanding.

You will help own the platform from an incoming SIP/WebRTC call through real-time speech processing, reasoning, orchestration and generated audio response.

Location, work model and compensation

• Location: Bengaluru or Noida
• Work model: Hybrid — 3 days/week in office
• Compensation: ₹1.5–2 crore fixed + performance-linked compensation + ESOPs
• Search: Confidential

What you will own

• Own the next-generation real-time Voice AI platform.
• Work across SIP, RTP, WebRTC and speech-to-speech systems.
• Build and evolve STT–LLM–TTS pipelines and orchestration.
• Optimise GPU inference, latency, reliability and scale.
• Remain a deeply hands-on Principal IC working closely with the CTO and senior engineers.

Required production experience

• SIP, RTP, WebRTC and telephony-native media systems.
• Real-time Voice AI and speech-to-speech platforms.
• Streaming STT, LLM orchestration and TTS.
• Barge-in, VAD, endpointing and full-duplex interaction.
• Tool calling, RAG, workflow execution and human escalation.
• GPU inference and optimisation using stacks such as vLLM, Triton, TensorRT, CUDA, ONNX or Faster-Whisper.
• Distributed systems, Kubernetes, observability, fault tolerance and high-scale production operations.
• Measurable latency, concurrency, throughput or infrastructure-cost improvements.

This is not a conventional engineering-management role

The successful candidate will work directly with the CTO and senior engineers while continuing to architect, code, troubleshoot and operate critical systems.

We want evidence of what you personally built

Strong applications should be able to answer questions such as:

• What platform did you personally design?
• Which components did you personally code?
• What production scale did you operate?
• What were the real p95/p99 latency numbers?
• What difficult failure did you personally diagnose?
• What inference or infrastructure optimisation did you deliver, and what changed as a result?

Relevant backgrounds

Exceptional candidates may come from Voice AI, Conversational AI, CPaaS, CCaaS, Cloud Telephony, WebRTC, Speech AI, ASR/TTS or large-scale distributed communications platforms.

Strong Staff-level engineers with unusually deep hands-on Voice AI and platform ownership may also be considered.
