Machine Learning Data Scientist

Apple's Hardware group is home to some of the world's most advanced technologies - powering the experiences that define Apple products. We are looking for a talented and curious ML Data Scientist to join our growing Machine Learning team in Herzliya. In this role, you will help create the full data lifecycle that underpins our models: from designing what data we collect, through curation and quality monitoring, to running rigorous experiments that drive model improvements. You will work closely with other ML and Data Engineering teams to ensure our models are trained on the best possible data, reaching the best accuracy - and that we deeply understand when and why they don't perform as expected.DescriptionAs an ML Data Scientist on this team, you will play a central role in shaping the data that powers our ML models. You will:Investigate model failures - identify patterns, hypothesize root causes, and work with the team to implement fixesOwn data curation: evaluate, clean, and curate datasets to maximize model training qualityDesign and execute experiments end-to-end: from defining the question and data collection escort, through analysis and statistical validation, to presenting clear conclusions and driving implementationDefine data collection strategies - collaborate with others to decide what data we should be collecting and whyDesign and maintain monitoring solutions with others to ensure ongoing data quality and integrity at scalePreferred QualificationsExperience with applied speech, audio or signal processing ML systemsExperience with data-efficient training strategiesExperience with continual or online learningFamiliarity with data quality frameworks, monitoring pipelines, and data validation at scaleStrong statistical foundation - hypothesis testing, uncertainty quantification, evaluation metrics designPh.D. n Computer Science, Electrical Engineering, Computational Biology/Neuroscience, Mathematics, Statistics, or a related fieldMinimum QualificationsM.Sc. in Computer Science, Electrical Engineering, Computational Biology/Neuroscience, Mathematics, Statistics, or a related field5+ years of industry experience in applied machine learning, data science, or a related fieldStrong hands-on experience with Python, PyTorch and SQL for large-scale data analysis and pipeline developmentHands-on experience with the full ML experimentation cycle: problem definition, data collection, statistical analysis, and conclusion-driven iterationProven ability to analyze model failures and translate findings into concrete improvementsStrong analytical thinking and ability to independently define and drive research directionsExcellent cross-functional communication skills - ability to work effectively with other ML and Data Engineers
