Responsibilities
- Apply low-bit quantization to LLMs, VLMs, and multimodal generative AI models while maintaining accuracy and output quality.
- Use knowledge distillation to transfer capabilities from larger teacher models to smaller student models for efficient multimodal reasoning across text, image, and audio inputs.
- Implement pruning methods to remove redundant parameters and attention heads while preserving task performance.
- Analyze trade-offs among model size, latency, memory, computational overhead, and accuracy across compression approaches.
- Research and apply mixed-precision quantization, adaptive pruning schedules, intermediate feature matching, and other advanced compression strategies.
- Build robust model-compression pipelines and address bottlenecks in production inference for edge devices.
- Establish performance and fidelity metrics for compressed models.
- Stay current with research in compression for multimodal and generative architectures.
- Document methodologies, experiments, and results to support reproducibility, collaboration, and stakeholder communication.
- Author technical papers and publish findings in leading AI and machine learning conferences.
Requirements
- Bachelor’s degree in Computer Science or a related field.
- Ideally, a PhD in NLP, Machine Learning, or a related field, with a strong AI R&D track record and publications in A* conferences.
- Experience with PyTorch or an equivalent deep learning framework.
- Hands-on experience with both Quantization-Aware Training (QAT) and Post-Training Quantization (PTQ).
- Research and hands-on experience applying knowledge distillation to compress large models into smaller, efficient models.
- Research and hands-on experience applying model pruning to compress large models into smaller, efficient models.
- Strong understanding of neural network architectures and training, including transformers, LLMs, VLMs, backpropagation, optimization, and fine-tuning.
- Familiarity with C++ is preferred, particularly for low-level quantization kernels or inference optimizations.
- Excellent English communication skills.
Benefits
- Remote work with a globally distributed team.
- Opportunity to contribute to AI research and publish findings at top-tier conferences.
- Work on multimodal AI systems intended for efficient deployment on resource-constrained edge devices.
