About the job

Requirements
  • PhD in a technical field or equivalent practical experience.
  • Experience with algorithmic architectures, data sources, and training and inference techniques for generative multimodal models, especially for robotics applications such as VLAs and WAMs.
  • Experience optimizing models and systems, including performance tuning, experimentation, and debugging.
  • Experience with robot policy training using imitation learning and related techniques.
  • Experience navigating practical pre-training considerations, including data quality, mixture optimization, data labeling, systematic benchmarking, scaling ladders, and performance hill-climbing.
  • Experience managing large volumes of multimodal data and optimizing data mixtures for training general, non-robotics frontier models, including large language models, vision-language models, image/video generation, and world models.
Responsibilities
  • Drive data quality, acquisition, and labeling strategies, and oversee mixture optimization for robotics foundation models.
  • Coordinate training runs, improve training recipes, and systematically hill-climb model performance against benchmarks.
  • Build and maintain the software tools and processes required to iterate on research ideas quickly and verify data quality through robot policy training.
  • Contribute to the wider research agenda, including reinforcement learning, vision-language-action modeling, world-action models, and simulation.
  • Set up large-scale tests and deploy promising ideas quickly and broadly, managing deadlines and deliverables while applying current theories to develop products, processes, or technologies.
  • Create experiments and prototype implementations, and design new architectures.
  • Contribute to the wider research community by sharing and publishing findings, with ideas informed by internal projects and collaborations with partner universities and technical institutes.
Desired Qualifications
  • Practical experience in hill-climbing model performance, such as iteratively improving training recipes and model benchmarks.
  • Experience working with simulators and real-world robotic platforms, such as dexterous manipulation and multimodal sensing.
  • Experience with benchmarking, different data sources, data labeling strategies, and data mixture optimization for robotics foundation models.
  • Ability to bring research from the lab to robust, real-world robotic systems.
  • Ability to build and maintain software tools for rapid iteration on research ideas.

About the company

Google runs the world's most used search engine and free services such as YouTube, Android, and Gmail, and it builds the Gemini AI models that work inside them. In 2017, its researchers invented the transformer, the neural network design behind ChatGPT and most other AI chatbots. People use these services without paying, and Google earns most of its money from ads placed beside search results and YouTube videos. Businesses rent computing power and Gemini models through Google Cloud, and Google also sells subscriptions and Pixel phones. Larry Page and Sergey Brin founded Google in 1998 as Stanford PhD students; it is based in Mountain View, California, United States, and is the main business of parent company Alphabet.

Simplify's Take

What believers are saying

  • Gemini caught on: its app's monthly users rose from 400 million in May 2025 to 1 billion by August 2026.
  • Cloud work is booked years ahead: Google Cloud had $514 billion of signed contracts still to deliver in June 2026.
  • Stock awards gained value: Alphabet shares rose 44% in the 12 months to October 2026, versus 2% for Microsoft.

What critics are saying

  • Cloud is still third: Google held 15% market share in the June 2026 quarter, behind Amazon's 28% and Microsoft's 20%.
  • AI spending outruns cash: Alphabet spent $44.9 billion on equipment in the June 2026 quarter, more than operations generated.
  • AI leadership is turning over: in August 2026, Demis Hassabis handed off running Google DeepMind, and veteran Jeff Dean left.

What makes Google unique

  • Consumer apps earn most profit: Google Services made $39.5 billion operating profit in the June 2026 quarter, 4.5 times Cloud.
  • Rivals rent its homemade AI chips: Claude maker Anthropic agreed in October 2025 to use up to 1 million TPUs.
  • Android dominates mobile browsing: it had 69% of global mobile web use in September 2026, versus 31% for iPhones.
