Research Engineer, Gemini Personalization

Snapshot:

We are the Gemini App team in Google DeepMind, building the everyday AI assistant from Google. Be at the forefront of AI innovation with Gemini, featuring native multimodality, an expansive context window (up to 2 million tokens), and superior performance. Our mission is to empower billions with deeply personalised and helpful products, delivering an experience users love.

In this role you will be a part of a team building a personal AI assistant. One that doesn’t just answer general questions, but understands you — tailoring its help to your specific interests, passions, and curiosities.

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:

As a Research Engineer, you'll play a key role in building the state-of-the-art personalized AI assistant on Gemini. Our personalization research encompasses model innovation, post-training refinement, advanced evaluation, benchmark creation, data generation, and scalable deployment.

This includes improving the model’s ability to reason about user information, creating robust evaluation frameworks to measure personalization quality, and building scalable systems to deliver tailored experiences to a wide user base. A key aspect of the work involves continuous experimentation and refinement to push the boundaries of what a truly personal AI assistant can achieve.

About You:

We seek out individuals who thrive in ambiguity and who are willing to help out with whatever moves prototypes forward. We regularly need to invent novel solutions to problems, and often change course if our ideas don’t work out, so flexibility and adaptability to work on any project is a must.

In order to set you up for success as a Research Engineer at Google DeepMind, we look for the following skills and experience:

• BSc, MSc or PhD/DPhil degree in computer science, mathematics, applied stats, machine learning or similar experience working in industry
