Software Engineer, Personalization, Gemini App, Google DeepMind

Snapshot Make Gemini App the most personal assistant. Build personalization-related user-facing features spanning both the Gemini App stack and the Gemini models behind it. Identify quality gaps and issues, and take end-to-end ownership over the improvements. Work closely with research scientists, other software engineers, and cross-functional partners.

About Us

Artificial Intelligence could be one of humanity’s most useful inventions. At Google DeepMind, we’re 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

Join the Gemini App Personalization team in order to make Gemini App the most personal assistant. Gemini App is Google’s flagship LLM product, where you'll contribute to building cutting-edge personalization features on top of state-of-the-art Gemini models. Personalization is a top priority for the Gemini App, as we aim to: Build and launch new Gemini App personalization features and capabilities across all surfaces and powering all other Gemini App features and components.

Expand or develop new personalization-related capabilities (e.g. understanding relevant personal information and using it appropriately in model responses and tool invocations) spanning both the Gemini App stack and the state-of-the-art Gemini models that are powering it. Personalization features and capabilities are reaching hundreds of millions of users and are frequently highlighted by leads in high visibility external events (e.g.

Google I/O, Made by Google).

Key Responsibilities

Act as primary owner and critical judge for specific Personalization features/areas. You will define the key metrics, evaluation standards, and acceptance criteria that guide development. Own the end-to-end lifecycle of complex quality or infrastructure improvements from hypothesis and experimentation to production deployment across both fine-tunable and frozen model architectures.

Propose and take end-to-end ownership over targeted quality or infrastructure improvements. Partner closely with research scientists, engineers and cross-functional partners (product and program managers) to advance the business goals of the organization. Influence and align with senior stakeholders and cross-functional leaders (Product, Research, Program Management) to shape the multi-quarter Personalization strategy and maximize organizational impact.
