Apple Services Engineering (ASE) powers many AI features across App Store, Music, Video and more. We build deeply personal products with the goal of representing users around the globe authentically. We work continuously to avoid perpetuating systemic biases and maintain safe and trustworthy experiences across our AI tools and models.

Description

Our team, part of Apple Services Engineering, is looking for an ML Research Engineer to lead the design and continuous development of automated benchmarking methodologies. In this role, you will investigate the behavior of media-related agents, craft rigorous evaluation frameworks and techniques, and establish scientific standards for assessing quality features. This role supports the development of scalable evaluation techniques that ensure our engineers have the right tools to assess candidate models and product features for optimal performance. The capabilities you build will allow for the generation of benchmark datasets and evaluation methodologies for model and application outputs, at scale, to enable engineering teams to translate insights into actionable engineering and product improvements. This role blends deep technical expertise with strong analytical judgment to develop tools and capabilities for assessing and improving the behavior of advanced AI/ML models. You will work cross-functionally with Engineering and Project Managers, Product, Safety, and Editorial teams to develop a suite of technologies to ensure that AI experiences are reliable, safe, and aligned with human expectations. The successful candidate will take a proactive approach to working independently and collaboratively on a wide range of projects. In this role, you will work alongside an impactful team, collaborating with ML and data scientists, software developers, project managers, and other teams at Apple to understand requirements and translate them into scalable, reliable, and efficient evaluation frameworks.
