Senior Applied Research Engineer - Model Compression

We compress large language models (LLMs). Our information-theoretic structural pruning and quantization algorithm shrinks model footprints by over 80% without retraining, in hours rather than weeks. 

This is an applied research role. You'll develop new compression methods and ship them, not write papers about them. The cycle is short: read the literature, prototype, benchmark on real models, integrate into our pipeline, iterate with customers running compressed models in production.

You'll own significant technical scope from day one. Expect to work across the stack: pruning algorithms, quantization, evaluation infrastructure, and the production code that customers actually use.

• Improving and extending our structural pruning algorithm to new architectures (MoE, multimodal, vision-language)
• Combining pruning with quantization (NVFP4/FP8/INT4, sub-4 bit mixed precision) in our compression pipeline
• Expanding and improving our model retraining pipeline (SFT, GKD, DPO, GRPO) 
• Compressing customer models (Llama, Qwen, Gemma, and proprietary fine-tunes) for cloud and edge deployment
• Hardware-aware optimization for different accelerator targets (A100/H100/B300 and edge hardware)
