Job Responsibility
Job Responsibility
  • Apply and extend compression recipes (knowledge distillation, structured pruning, and post-training and quantization-aware quantization including low-bit and mixed-precision) to assigned models, achieving 20x to 100x compression while preserving model quality
  • Design and run healing recipes (fine-tuning and distillation that recover accuracy lost to compression), iterating on data mixes, objectives, and training settings until the compressed model meets its quality bar
  • Track emerging model architectures and dissect how they work internally, so you can choose where to compress, anticipate where accuracy will break, and design recovery strategies grounded in the model's actual structure
  • Build a library of compression-ready model entries: reference implementations, compression recipes, model cards, and benchmark results that partner teams can run self-service to produce deployment-ready artifacts for edge and cloud targets
  • Define the datasets, benchmarks, and KPIs that matter for your models, and build evaluation methodology that makes accuracy, latency, memory, and cost trade-offs explicit
  • Run fast feasibility gates on new model families and modalities before committing to long efforts, and pivot early when a candidate does not clear the bar
  • Capture platform friction as high-signal feedback: minimal reproductions and tracked fix requests that help platform and compression-science partners root-cause issues, so partner teams never rediscover the same blockers
  • Write reproducible, testable, well-documented code that meets the SDE I bar, so your recipes and results can be reproduced and built on by others
  • Collaborate with Applied Scientists, platform and compiler engineers, hardware architects, and partner teams
  • mentor interns and help newer teammates ramp up
