This includes: Training & Data: You can strategically guide decisions on data acquisition, pre-training vs. fine-tuning, and novel training methodologies
Inference & Optimization: You deeply understand the trade-offs between latency, cost, and performance, and can drive the roadmap for model quantization, distillation, and efficient serving
Mastery of Applied AI Craft: You know how to turn a powerful but raw model into a magical, reliable product. You are an expert in: Evals: Designing and implementing robust, multi-modal evaluation frameworks (both automated and human-in-the-loop) to rigorously measure and improve model quality
Agentic Systems: Architecting and building AI agents that can reason, plan, and use tools to accomplish complex tasks
Platform & API Architecture: You are a true platform builder. You know how to design clean, scalable, and intuitive APIs that developers love. You obsess over developer experience (DX), documentation, and building a platform that accelerates the entire organization
Proven AI Shipping Experience: You have a track record of shipping V1 AI-powered products, from consumer-facing features to developer-level platform services
Strategic & Systems Thinking: You can reason from first principles about the long-term trajectory of AI. You can connect advancements in research to concrete product opportunities and build a coherent technical strategy that spans multiple years

Startup DNA: You've worked at a seed or Series A startup or have tried to build your own thing
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
