About the job

Google's software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with information and one another. Our products need to handle information at massive scale, and extend well beyond web search. We're looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day. As a software engineer, you will work on a specific project critical to Google’s needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward.

In Google's Platforms and Devices (P&D) Health team, our mission is to empower users to live longer and healthier lives through a deeply personalized, AI-powered health experience.

The Health Platforms and Devices team builds innovative products and services that help our users live longer, healthier lives. We bring together the best of Google technologies and AI, health behavior science, and user-centered design to help users organize the health and wellness data, get insight from it, and take action toward their health goals. We do this with a suite of apps, services, and health wearables. We aim to make consumer health more personal, proactive, and actionable.

• Act as the key technical authority for the agentic platform that delivers PHA. Build and grow the technical expertise in the broader engineering organization to deliver agentic capabilities. Be a role model for engineering excellence in all dimensions.
• Lead the technical effort to productionize novel agent capabilities from Google Deepmind (GDM) and research. Evaluate new algorithms and agent tasks, define integration paths, and create a "simplified eval story" to validate them for clinical and product readiness.
• Partner with engineering organization leads, product, UXR, clinical safety to align product roadmap with technical strategy.
