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 this role, you will be responsible for algorithms and systems in production, such as the Fused Location Provider (FLP) on Android with users on Android phones, motion algorithms for the Google Pixel Watches, and work on industry-first features that will enable computing experiences.Behind everything our users see online is the architecture built by the Technical Infrastructure team to keep it running. From developing and maintaining our data centers to building the next generation of Google platforms, we make Google's product portfolio possible. We're proud to be our engineers' engineers and love voiding warranties by taking things apart so we can rebuild them. We keep our networks up and running, ensuring our users have the best and fastest experience possible. + Review code developed by other developers and provide feedback to ensure best practices (e.g., style guidelines, checking code in, accuracy, testability, and efficiency). + Support algorithm development by creating and maintaining validation pipelines also extend and simplify existing validation pipelines. + Update existing Distance/Pace/Trajectory validation, create validation jobs for other motion algorithms on phone (e.g., advanced running metrics (ARD), Elevation, swimming) collected from devices. + Establish a data management system for validation runs, featuring automated logging with detailed metadata (e.g., command, data source, code version), to ensure all results are centrally cataloged and readily accessible in a database for streamlined reporting and enhanced reproducibility. + Integration of Cumulative Distribution Function (CDF) to what traces/analysis. Google is proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.
