📋 Description

• Lead the full AI product lifecycle: from identifying user pain points and defining KPIs to training foundation models and measuring real-world impact. • Design and execute rigorous experiments (A/B tests, causal inference) to validate new AI features and drive product optimizations. • Partner with Product Managers, Designers, and Engineers to translate business goals into a technical AI roadmap, ensuring our model development stays aligned with user needs and technical feasibility. • Build and maintain production-grade training pipelines and evaluation harnesses using reproducible, well-tested code. • Analyze production feedback and user interactions to iteratively refine models and maximize value. • Foster a collaborative culture: mentor teammates, simplify complex problems, and drive iterative, high-impact delivery.

🎯 Requirements

• Deep product sense: define success metrics, translate vague business objectives into measurable hypotheses, and measure product impact through A/B testing and causal inference. • Experience with product analytics to derive actionable insights that inform product roadmaps. • Proven track record of converting model outputs into business outcomes; comfortable communicating technical findings to cross-functional partners (PMs, designers, engineers) to drive alignment. • Experience designing, training, and shipping production AI models, with depth in transformer architectures and LLMs. • Solid fundamentals (attention, tokenization, embeddings, regularization) and failure mode analysis. • Familiarity with fine-tuning (LoRA, adapters), knowledge distillation, quantization, and instruction tuning.
