With a PhD in Machine Learning and extensive experience in transformer architectures, I have developed long-context models that reduce computational costs while preserving quality. My research has been published in top-tier venues, and I have a strong record of mentoring junior scientists. I am drawn to Nebius's mission of making open-source AI competitive for real-world use, and I look forward to contributing to your research stream. Thank you for your consideration. Copy Sample interview questionsCan you describe your experience with designing efficient attention mechanisms?In my PhD, I developed a sparse attention variant that reduced memory usage by 40% while maintaining accuracy on long-document tasks. I implemented it in PyTorch and tested it on sequences up to 128k tokens, comparing against full attention baseline. How do you approach a research problem that seems impossible to solve with current methods? I first break the problem into smaller, testable hypotheses. I then design minimal experiments to validate each hypothesis, often using smaller models to quickly test ideas before scaling up. This iterative process helps identify the most promising direction. Describe how you would collaborate with an engineering team to bring a research prototype to production. I would work closely with engineers to understand production constraints, such as latency and memory. I would provide optimized code, benchmarks, and clear documentation, and we would iterate on the implementation to ensure robustness. What is your approach to mentoring junior researchers? I focus on building their fundamental understanding and encouraging them to ask critical questions. I set clear research goals and provide regular feedback, while giving them the freedom to explore their own ideas. How do you stay current with the rapid advances in model architectures? I regularly read arXiv papers, attend conferences, and re-implement key ideas to understand their nuances. I also participate in community open-source projects, which helps me gain practical insights. About Nebius: Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.
