Voice AI Engineer

About The Role

Job Title: Voice AI Engineer

We’re shaping the next era of human-machine interaction — one where conversations flow seamlessly in real time with voice-first intelligence.

As a Voice AI Engineer, you won't just be writing code — you'll be crafting the building blocks of cutting-edge, scalable voice agents that can listen, speak, and think. If you’re passionate about combining backend engineering, real-time processing, and conversational AI, you’ll thrive here.

Expect rapid prototyping, hands-on ownership, and direct impact in a space where innovation meets execution.

Roles & Responsibilities

• Design, build, and maintain real-time audio communication pipelines using WebSockets, Redis, and Django Channels.
• Integrate and optimize Speech-to-Text (STT) and Text-to-Speech (TTS) engines for high-performance, low-latency communication.
• Collaborate with cross-functional teams to embed Large Language Models (LLMs) (like OpenAI, Claude, Gemini) into dynamic conversational flows.
• Continuously monitor, test, and debug production systems to maintain high system uptime and low error rates.
• Conduct R&D-style experiments to validate new tools, frameworks, or model integrations — from Whisper to Eleven Labs.
• Write clean, modular, well-documented code, and participate in code reviews and architecture discussions.

Tech Stack You’ll Work On:

• Backend: Python, Django REST Framework (DRF), Django Channels
• Realtime: WebSockets, Redis Pub/Sub
• Async / Task Queue: Celery
• Voice AI: STT (Speech-to-Text), TTS (Text-to-Speech), LLM integrations
• Infrastructure: AWS
  
  

What We’re Looking For

• Having a hunch about working with VoiceAI
• A builder's mindset — someone who loves tinkering, rapid prototyping, and solving complex problems
• Development experience using Python/Django
• Understanding of asynchronous programming, WebSockets, and task queues like Celery
• Enthusiasm or prior exposure to voice technologies (STT/TTS) or LLM-driven applications
• Bonus Points
• Hands-on experience with STT/TTS tools like Whisper, ElevenLabs, Google Cloud STT/TTS
