Sr. Research Engineer/Scientist (all levels), Efficient Models

Sr. Research Engineer/Scientist (all levels), Efficient Models Location: Seattle Employment Type: Regular Job Code: A250046 About the Team The Vision‑Applied Research team focuses on applied research in Generative AI and CV/Multimodal Understanding, and delivering intelligent solutions to TikTok products, enabling users to make and share creative content in a much easier way. The team has research groups dedicated to generative models for content creation, image generation, video synthesis, intelligent image/video editing, and virtual humans. Responsibilities Develop distillation frameworks, model acceleration, hardware‑efficient inference, and their applications. Develop efficient algorithms and architectures for large‑scale generative and multimodal models, using techniques such as step distillation, cfg distillation, quantization, and other methods to improve model efficiency (e.g., image generation, video generation, VLM). Advance scalable generative modeling approaches, including diffusion and autoregressive models, with a focus on acceleration and efficiency. Qualifications Minimum Qualifications: B.S. in Computer Science or related fields, or equivalent experience Expertise in efficient models with deep understanding of computational bottlenecks and acceleration methods Proficiency in training generative AI or LLM models using widely adopted frameworks and tools such as PyTorch and JAX Strong communication and collaboration skills in fast-paced environments Preferred Qualifications: Ph.D. in GenAI, MLSys or equivalent experience Extensive research experiences in broad GenAI, MLSys, LLM areas Proven experiences in at least one of the following areas: image/video generation and editing; model compression (e.g., quantization, step/cfg distillation); efficient architectures (e.g., MoE, window attention); efficient model design; or reinforcement learning training methods (e.g., RLHF, DPO, GRPO) Job Information Base salary range for this position in Seattle is $232,560 to $427,500 annually.
