Staff Software Engineering, GenAI Applications, YouTube

• Design and implement dynamic context construction strategies for RAG (Retrieval Augmented Generation) systems.
• Solve challenges related to limited context versus massive schema documentation, optimizing for precision, recall, and cost.
• Lead the evaluation and fine-tuning of embedding strategy (dense, sparse, and hybrid) to capture domain-specific YouTube terminology. You will decide how we represent data tables, column definitions, and debug logs in vector space.
• Build data pipelines that keep our semantic index fresh in real-time as YouTube’s data schemas evolve.
• Mentor Senior Engineers, drive technical roadmap planning, and collaborate with partners in Google DeepMind and YouTube infrastructure to adopt research.

Minimum qualifications:

• Bachelor's degree or equivalent practical experience.
• 8 years of experience in software development.
  
• 5 years of experience testing, and launching software products, and 3 years of experience with software design and architecture.
• 5 years of experience with machine learning algorithms and tools (e.g. TensorFlow), artificial intelligence, deep learning, or natural language processing.

Preferred qualifications:

• 8 years of experience with data structures and algorithms.
• Experience leading technical strategy for large-scale projects and mentoring executive engineers.
• Experience designing and implementing complex context retrieval systems (context scaffolding) for large language models in production.
• Proficiency in SQL.
• Understanding of vector space models, semantic search, and experience evaluating embedding techniques (e.g., dense versus sparse retrieval, re-ranking strategies).
• Ability to independently query massive datasets to diagnose model behavior, identify edge cases, and drive data-informed architectural decisions.
