Senior Software Engineer
Senior Software Engineer driving Tavus's real-time Conversational Video Interface (CVI). Own end-to-end feature development for multimodal AI conversations, integrate research models, optimize latency, and proactively fix issues in live human-AI interactions. Requires deep Python concurrency expertise and real-time systems experience.
About the job
What you'll own
- Ship features end-to-end: take loosely defined product priorities (e.g. voice localization for accent support, multilingual sentence endpointing) and turn them into specs, architecture, and shipped features.
- Partner with Research to bring state-of-the-art real-time models into the Conversational Video Interface (CVI). This may involve dipping into research territory.
- Fix issues proactively: address flaky processes or slow paths without needing tickets or permission.
What this role has shipped
- Guided Browser Control: framework allowing PALs to drive a real web browser mid-conversation, narrating clicks and scrolls.
- Magic Canvas: interactive cards rendered on the video stream (questions, text boxes, calendars, charts, alerts).
- Memories and Knowledge Base: context layer for recalling past conversations and pulling from document stores in real time.
- Utterance-to-utterance optimization: reducing conversational latency by hundreds of milliseconds.
Requirements
- Fluent in Python with deep expertise in concurrent programs (asyncio, multiprocessing, event loops, GIL, shared memory).
- Experience building real-time systems (video, audio, or model inference) and working within millisecond latency budgets.
- Senior track record of setting direction, owning decisions, and delivering results.
- Ability to explain complex concepts clearly and teach others.
Nice-to-haves
- 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.
