About the Job

Requirements

  • A bachelor's degree or equivalent practical experience.
  • Eight years of experience in software development.
  • Five years of experience testing and launching software products.
  • Three years of experience with software design and architecture.
  • Experience with large language models, reinforcement learning, and deep learning.

Responsibilities

  • Specialize in core modeling and post-training experience, and drive the research process for large-scale agent post-training from hypothesis formulation to delivery in the Gemini model recipe.
  • Design and execute ablation studies to validate research hypotheses and accelerate experimental feedback loops.
  • Communicate research findings, progress, and outcomes to the broader team through visualizations and reports.
  • Develop research infrastructure and utilities for data analysis and model evaluations using standard engineering practices.
  • Collaborate with other research scientists and engineers to maintain a regular feedback and communication loop.
  • Research, develop, and scale foundational post-training methods that convert foundation models into autonomous, adaptive agents for consumers.
  • Focus on reinforcement learning, targeted data creation, and persistent context architectures so models retain user-specific state reliably over time and adapt to individual users.
  • Build training datasets and evaluation frameworks to test long-horizon reasoning, uncover failure modes, and measure agent reliability across complex workflows.

Desired Qualifications

  • A master's degree or PhD in Engineering, Computer Science, or a related technical field.
  • Eight years of experience with data structures and algorithms.
  • Three years of experience in a technical leadership role leading project teams and setting technical direction.
  • Three years of experience working in a complex, matrixed organization involving cross-functional or cross-business projects.
  • Candidates with primarily machine learning infrastructure backgrounds may find that this role is not the right profile for their skill set.

About the Company

Google

Runs Search and YouTube and builds Gemini AI

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.
