Research Engineer, Post-Training for Code Security Analysis

About Us

Artificial Intelligence could be one of humanitys most useful inventions. At Google DeepMind were a team of scientists engineers machine learning experts and more working together to advance the state of the art in artificial intelligence. We use our technologies for widespread public benefit and scientific discovery and collaborate with others on critical challenges ensuring safety and ethics are the highest priority.

The Role

In this role youll work with a team of elite researchers and engineers to design and implement post-training strategies that enhance Geminis capabilities in code security analysis. You will bring contributions to our ML innovation post-training refinement (SFT/RLHF) advanced evaluation and data generation to ensure our models can reliably perform safe and powerful code security analysis.

Key responsibilities:

• Design and Implement advanced post-training algorithms (SFT RLHF RLAIF) to optimize Gemini for code security tasks and secure coding practices.
• Diagnose and interpret training outcomes (regressions in coding ability gains in security reasoning) and propose solutions to improve model capabilities.
• Actively monitor and evolve the systems performance through metric design.
• Develop reliable automated evaluation pipelines for code security that are strongly correlated with human security expert judgment.
• Construct complex benchmarks to probe the limits of the models ability to reason about control flow memory safety and software weakness.

About You

We are seeking individuals who excel in fast-pacing environments and are eager to contribute to the advancement of AI. We highly value the ability to invent novel solutions to complex problems embracing a can-do and fail-fast mindset.
