Requirements
  • A PhD in Computer Science, electrical engineering and computer science, Mathematics, or a closely related field; alternatively, a BS/MS with a strong research engineering background from frontier labs.
  • A proven track record of building end-to-end machine learning pipelines, including data curation, preparation, and large-scale large language model fine-tuning using reinforcement learning from human feedback and supervised fine-tuning.
  • Experience diagnosing training slowdowns, building instrumentation to monitor system health, and fixing complex issues in distributed environments.
Responsibilities
  • Build, maintain, and improve the algorithms and engineering systems used to post-train models for chip designs, focusing on improving training speed and reliability.
  • Profile reinforcement learning and training pipelines to detect bottlenecks and implement optimizations for high-performance training setups.
  • Collaborate closely with machine learning researchers to implement stable and fast versions of new fine-tuning recipes, such as reinforcement learning from human feedback and supervised fine-tuning, on different model architectures.
Desired Qualifications
  • Experience implementing large language model fine-tuning algorithms, such as reinforcement learning from human feedback, and modifying systems based on model architectures.
  • Experience working on the post-training or infrastructure team at frontier labs such as OpenAI, Anthropic, DeepMind, Mistral, MSL, or Cohere.
  • A foundation in electrical engineering or computer engineering and chip-design or verification processes.
  • Publications in top machine learning venues such as NeurIPS, ICLR, or ICML, or systems venues such as OSDI or SOSP.
  • Experience as a founding engineer or early hire at an artificial intelligence deep-tech startup.
