Job description

Our Mission Reflection’s mission is to build open superintelligence and make it accessible to all . We’re developing open weight models for individuals, agents, enterprises, and even nation states. Our team of AI researchers and company builders come from DeepMind, OpenAI, Google Brain, Meta, Character.AI, Anthropic and beyond. About the Role: Research and build solutions across algorithms, scaling laws, data processing, optimizers, and model architecture. Design and run scientific experiments to advance our understanding of scaling large language models and data efficiency. Implement state-of-the-art methods from the deep learning literature. Lead small research projects independently while collaborating on larger initiatives Optimize the training infrastructure for efficient scaling. Contribute across the entire stack, from low-level optimizations to high-level model design. About You: Graduate degree (MS or PhD) in Computer Science, Machine Learning, or related discipline. Solid software engineering capabilities with experience building large-scale systems. Experience with large-scale ETL workflows and training data preparation. Deep understanding of large-scale ML, especially a...
