About the Role

We're hiring a Senior Software Engineer to be a technical driver on Tavus's Conversational Video Interface, our multimodal real-time conversational product. It's a hands-on role where your code runs in the middle of live conversations between people and AI Humans (PALs). You will ship features end-to-end, partner with Research to bring state-of-the-art real-time models into CVI, and proactively fix issues and optimize processes.

Responsibilities

  • Ship features end-to-end, from loosely defined product priorities to shipped features.
  • Partner with Research to integrate state-of-the-art real-time models into CVI.
  • Proactively identify and address flaky processes or slow paths without requiring explicit direction.
  • Take ownership of product priorities, including voice localization for accent support and multilingual sentence endpointing.
  • Develop and implement features such as Guided Browser Control, Magic Canvas, Memories and Knowledge Base, and utterance-to-utterance optimization.

Requirements

  • Fluent in Python with deep expertise in concurrent programming (asyncio, multiprocessing, event loops, GIL, shared memory).
  • Experience building real-time systems (video, audio, or model inference) with an understanding of millisecond latency budgets.
  • A senior track record of setting direction, owning decisions, and delivering projects.
  • Ability to explain complex concepts clearly and teach others.
  • Experience with GPUs and GPU management.
  • Deep experience with video streaming over WebRTC.
  • Deep experience with LLMs and agentic frameworks.
  • Extensive experience with low-level systems.
