The role requires software engineering expertise to develop and deploy highly scalable algorithms that are used by hundreds of millions of users every day across the globe. We collaborate with other engineers, feature teams, and business partners across a wide range of groups within Apple to identify problems, define solutions, execute plans, measure results and communicate these results to our partners. We have end-to-end responsibility for our solutions to these problems, from initial investigation, to solution proposal, to implementation, to long-term maintenance. A successful candidate will have a bent for applied research with a broad knowledge of machine learning and expertise in anomaly detection, predictive modeling, classification and optimization. We encourage our team to stay abreast of current research by attending conferences. We cultivate a collaborative work environment, but allow solution autonomy on projects.
