Role: You will join the data science team in a full-time role focused on model optimization for Quadric's custom GPNPU architecture. You will own quantization work for production models, extend our quantization library, and build the numerical accuracy testing and debugging infrastructure that the team relies on day to day.
Responsibilities:- Develop and deploy quantization workflows for vision and language models, taking models from FP32 reference to deployable low-precision implementations that meet accuracy targets.
- Investigate per-layer numerical error, identify accuracy regressions, and propose calibration, PTQ, or QAT strategies to recover lost accuracy.
- Extend Quadric's quantization library with new operators, observers, and algorithms.
- Build and maintain numerical accuracy testing infrastructure and debug tooling for neural networks running on the GPNPU.
- Collaborate with graph compiler, kernel, and hardware teams to co-design solutions that exploit the GPNPU's numerical capabilities.
Requirements- B.S., M.S., or Ph.D. in CS, EE, Applied Math, or a related field, completed within the last year.
- Strong Python skills and fluency with PyTorch (or TensorFlow), NumPy, and data-viz tools (Matplotlib/Plotly).
- Solid machine learning foundations; working knowledge of CNNs and Transformers.
- Interest in quantization, numerical representation, fixed-point arithmetic, or low-level performance.
- Ability to read research papers, evaluate the core ideas, and reproduce key results.
- Bonus: hands-on experience with quantization or model compression, or any of PyTorch FX/PTQ/QAT, TF-Lite, ONNX-Runtime, TVM, or MLIR Quant.
- Bonus: experience with embedded systems, DSPs, GPUs, or other accelerators.
- Bonus: published research, open-source contributions, or coursework projects in model optimization, efficient ML, or systems for ML.
Benefits- Competitive salary and meaningful equity
- Medical, dental, and vision plan options starting on day one
- 401(k) retirement plan
- Flexible paid time off (unlimited, non-accrual) to support work-life balance
- When working in-office, enjoy company-provided lunches and a stocked kitchen
- Convenient office location within walking distance of the Caltrain station
- Support for commuting, including monthly parking or Caltrain passes
- Downtown Burlingame office location, close to shops, cafes, and local amenities
- A politics-free, highly collaborative environment where talented people can do their best work and make an immediate impact
- The opportunity to build long-term career relationships in a company that values strong personal connections alongside professional excellence
