About the job
As the Principal Engineer you will focus on architecting and building the flagship GeminiApp infrastructure. You will serve as the technical anchor for the application and orchestration layer, owning the code quality, architectural decisions, and system design of new design systems and functionality. You will partner closely with Product, Design, and Engineering Directors to evolve our platform, personally engineering the complex, high-performance server-side infrastructure required to support fast chat interactions and agentic workflows. In this role, you will be a leader who can balance defining a long-term technical roadmap for a paradigm-shifting infrastructure and dive deep into code to drive high velocity, stability, and quality.
Artificial intelligence will be one humanity’s most transformative inventions. At Google DeepMind, we are a pioneering AI lab with exceptional interdisciplinary teams focused on advancing AI development to solve complex global challenges and accelerate high-quality product innovation for billions of users. We use our technologies for widespread public benefit and scientific discovery, ensuring safety and ethics are always our highest priority.
Responsibilities
- Architect the Gemini app serving and orchestration layers. Write the design docs and define the interfaces that ensure the codebase is scalable, modular, and capable of supporting rapid innovation.
- Design and implement robust CI/CD pipelines and experimentation platforms. Build the tooling that enables the wider engineering team to utilize A/B testing and feature flags to safely and quickly iterate.
- Drive application performance initiatives (performance, reliability, efficiency). Debug complex production issues and advocate for code quality standards to ensure the infrastructure scales to our product needs.
- Act as the strategic technical counterpart to product and design leadership. Assess feasibility of ambitious concepts and propose technical solutions that turn AI capabilities into reality.
- Mentor staff and senior engineers, lead code reviews, and foster a culture of technical accuracy, psychological safety, and user-centricity.
