• Research Contributions: You have published papers at top AI conferences (e.g., NeurIPS, ICML) or have made significant contributions to major open-source AI projects
• AI Ethics & Safety: You have a strong and nuanced understanding of the risks and ethical considerations of building powerful AI systems
• Hardware Knowledge: You understand the underlying hardware (GPUs, TPUs, interconnects) and how it impacts model architecture and performance

Education Requirements

• Bachelors Degree Required in Computer Science or related field
• Advanced Prompting: You are a master of prompt engineering, including sophisticated techniques like meta-prompting and Chain of Thought to elicit the best possible performance from models
