• Define and lead the LLM/SLM training strategy, including model selection, data strategy, and alignment approaches.
• Architect scalable and reusable training and evaluation pipelines for instruction tuning, preference optimization, and synthetic data workflows.
• Establish evaluation standards and benchmarks for model quality, hallucination reduction, safety, and reliability across teams.
• Drive adoption of efficient fine-tuning and inference optimization techniques (PEFT, quantization, distillation) at platform scale.
• Partner with platform and infrastructure teams to influence training and serving architecture, GPU utilization, and cost efficiency.
• Mentor senior and mid-level data scientists and engineers; raise the overall bar for model quality and engineering rigor.
• Act as a technical advisor to product and leadership on LLM capabilities, limitations, and trade-offs.
• Track cutting-edge research and proactively translate it into practical, enterprise-ready solutions.

Who You'll Work With: Join Forces with the Best   

You'll collaborate with a world-class team of AI architects, ML engineers, and domain experts at Silicon Valley, working together to build the next generation of enterprise AI systems.
