AI Engineer

The role

This engineer trains, fine-tunes, and serves generative models for realtime, interactive AI avatars. Work covers the full model lifecycle including data curation, training diffusion, video, and multimodal models to low-latency inference.

What you will do

• Train and fine-tune generative models for talking-head synthesis, audio-driven facial animation, and full-body avatar video
• Design data pipelines for large-scale video, audio, and multimodal datasets
• Optimize models for realtime serving with sub-200ms end-to-end latency
• Build and maintain training, evaluation, and deployment infrastructure on GPU clusters
• Define and track quality metrics and drive measurable gains
• Work with backend, product, and research teams to ship avatar features
• Keep up with research in generative video, multimodal AI, and neural rendering

Required qualifications

• 3+ years of hands-on ML engineering, or strong research experience with production-quality code, with a record of shipping deep learning models
• Deep expertise in PyTorch and modern DL workflows
• Able to read, reproduce, and extend research papers
• Strong background in one or more of: diffusion models, video generation, generative AI, computer vision, multimodal (audio+vision) AI, speech synthesis, neural rendering
• Solid Python engineering
• Distributed training on multi-GPU / multi-node setups
• Proven realtime inference optimization: TensorRT, ONNX, Triton Inference Server, CUDA, mixed precision, streaming pipelines
• Comfortable in ambiguous, fast-changing environments
• Proactive, ownership-driven
• Fast-learning startup mentality

Nice to have

• Talking-head, audio-driven animation, lip-sync, or digital human systems
• 3D Gaussian Splatting, NeRF, face reenactment, avatar synthesis
• Publications at top venues (NeurIPS, CVPR, ICCV, SIGGRAPH, ICLR, ICML)
• Notable open-source contributions

Benefits

• Competitive salary
• Equity
• Benefits
• Access to substantial GPU compute
