About this role

Senior AI Video Engineer building end-to-end AI image/video generation pipelines, researching and integrating generative models, and maintaining real-time avatar rendering infrastructure. You’ll optimize GPU inference, collaborate with ML teams, and ship production-ready AIGC features.

Key Responsibilities

Design and maintain end-to-end AI image / video generation pipelines
Research and integrate open-source generative models
Develop and optimize character consistency solutions (LoRA, IP-Adapter, ControlNet)
Collaborate on real-time / low-latency video generation (LiveKit, WebRTC)
Build and maintain GPU inference infrastructure

Technical Overview

Stack centers on Python, PyTorch, Diffusers with ComfyUI/A1111; extends to Node.js for APIs, GPU optimization (TensorRT, xformers), and real-time streaming (LiveKit/WebRTC). Focus areas include diffusion-model architectures and LoRA/IP-Adapter/ControlNet techniques.

Ideal Candidate

The ideal candidate is a senior AI/ML engineer with 3+ years building end-to-end AI image/video generation pipelines, deep experience with diffusion models, and hands-on work with real-time rendering and GPU optimization. They should be proficient in Python, PyTorch, and Diffusers, with Node.js experience for API wiring and live streaming tech like LiveKit or WebRTC.
