About the role

Role focused on turning modern ML techniques into scalable, high-performance systems for training, fine-tuning, and deploying large language models (LLMs) on Cerebras' AI platform. Work spans modeling and systems, emphasizing implementation, debugging, and production-ready ML pipelines for LLM development and reinforcement learning-based post-training.

Responsibilities

  • Apply post-training techniques (e.g. RLVR, RLHF, GRPO etc.) techniques to improve model performance.
  • Build and maintain evaluation pipelines to measure model performance across tasks and domains.
  • Debug issues across the ML stack, including data pipelines, training jobs, model outputs and mixed or lower precision computation.
  • Collaborate with researchers to translate ML ideas into efficient, scalable implementation.
  • Design, implement, and scale ML pipelines across all stages of LLM development (pretraining, fine-tuning, alignment).
  • Work with large datasets, including dataset generation, filtering, and synthetic data approaches.
  • Optimize training and inference workflows for performance, efficiency, and reliability.
  • Contribute high-quality, maintainable code to shared ML infrastructure.

Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
  • 4+ years of experience (including internships, research, or industry experience) working with machine learning systems; multiple positions for various levels.
  • Strong programming skills in Python.
  • Experience with ML frameworks such as PyTorch.
  • Solid understanding of machine learning fundamentals.
  • Familiarity with deep learning architectures, particularly transformers.
  • Ability to read and understand modern ML papers and implement key ideas.
