Tech Evaluation & Customization: Evaluate and benchmark open-source LLMs, CV, and multimodal models. Customize architectures to meet customer use-case requirements including quantization, pruning, distillation, and architecture search. Hardware-Aware Optimization: Work closely with performance engineers to tailor models for GPUs, CPUs, and emerging accelerators (e.g., AMD, ARM, or edge chips). Customer Collaboration: Partner with strategic customers to understand application needs and co-develop custom model optimization workflows and pipelines. Cross-Functional Leadership: Collaborate with product, engineering, MLOps, and systems teams to ensure end-to-end delivery of robust and production-grade models. Innovation & Technical Strategy: Stay ahead of AI optimization trends, propose new approaches, and guide architectural decisions around tooling, frameworks, and methodology. What you’ll need to be successful: Master’s or Ph.D. in Computer Science, Machine Learning, or related technical field. 8–10+ years in machine learning, AI R&D, or systems optimization roles. Deep experience with model optimization techniques: quantization (INT8/FP16), pruning, distillation, NAS, etc. Proven track record of working with LLMs, vision models, or multimodal architectures. Experience with deep learning frameworks (e.g., PyTorch, TensorFlow) and optimization tools (e.g., ONNX, TVM, TensorRT, Hugging Face Optimum). Strong software engineering skills in Python and/or C++. Demonstrated ability to translate AI research into high-performance production systems. Excellent communication skills and a customer-first mindset. What we offer: A competitive salary and benefits package, tailored to recognize your dedication and contributions. The opportunity to collaborate with leading experts in AI and cloud computing, learning from the best and the brightest, fostering continuous growth. An environment that values innovation, collaboration, and mutual respect. Support for personal and professional development, empowering you with the tools and resources to elevate your skills and leave a lasting impact. A pivotal role in the AI revolution, shaping the technologies that power the innovations of tomorrow.
