Principal Machine Learning Engineer

At Red Hat we believe the future of AI is open and we are on a mission to bring the power of open-source LLMs and vLLM to every enterprise. The Red Hat AI Inference team accelerates AI for the enterprise and brings operational simplicity to GenAI deployments. As leading developers, maintainers of the vLLM project, and inventors of state of the art techniques for model quantization and sparsification, our team provides a stable platform for enterprises to build, optimize, and scale LLM deployments.

As a Machine Learning Engineer focused on model optimization algorithms, you will work closely with our product and research teams to develop state of the art deep learning software. You will collaborate with technical and research teams to develop LLM training and deployment pipelines, implement model compression algorithms, and productize deep learning research. This role is for those who enjoy bridging research and production, optimizing large models, and contributing to open source AI tooling.

• Contribute to the design, development, and testing of various inference optimization algorithms in the LLM compressor, Speculators, and vLLM projects.
• Design, implement, and optimize model compression pipelines using techniques such as quantization and pruning.
• Develop and maintain speculative decoding frameworks to improve inference speed while maintaining model accuracy.
• Collaborate closely with research scientists to translate experimental ideas into robust, production ready systems.
• Profile and optimize end to end LLM performance, including memory usage, latency, and throughput.
• Benchmark, evaluate, and implement strategies for optimal performance on target hardware.
• Build tools to streamline model training, evaluation, and deployment.
• Participate in technical design discussions and propose innovative solutions to complex problems.
• Contribute to open source projects, code reviews, and documentation; collaborate with internal and external contributors.
• Mentor and guide team members, fostering a culture of continuous learning and innovation.
• Stay current with LLM architectures, inference optimizations, quantization research, and CPU/GPU hardware advancements.

• Strong understanding of machine learning and deep learning fundamentals with experience in one or more of LLM inference optimizations and NLP.
• Experience with tensor math libraries such as PyTorch and NumPy.
• Strong programming skills with proven experience implementing Python based machine learning solutions.
• Ability to develop and implement research ideas and algorithms.
• Experience with mathematical software, especially linear algebra.
• Understanding of linear algebra, gradients, probability, and graph theory.
• Strong communication skills with both technical and non technical team members.
• BS or MS in computer science, computer engineering, or a related field. A PhD in an ML related domain is considered a strong plus.
