We build the ML models that underlie Summarization, Smart Reply, Writing Tools, and other features deeply integrated into Apple products. Generative AI is a transformative technology that we have only just begun to incorporate into our digital lives, to help everyday people digest the deluge of information they receive and express themselves more clearly. On our team, you will help build the future and have a voice in the shape it takes., We are looking for a Senior Machine Learning Engineer to own the model quality of Summarization and other core Apple Intelligence features. You will develop the next generation of our ML models, so that they better serve the full range of our customers, across languages, writing styles, and other personal context, in a privacy-preserving way and to Apple's high standards of quality. You will design the architecture of the modeling pipelines that define our slice of Apple Intelligence, driving the direction of our team's efforts to produce user experiences that feel magical. You will join an ambitious, organized, and collaborative team. We're in a unique position to integrate the latest innovations from the ML community and work on features that reach everyday users, including your family and friends. You'll work closely with other teams across Apple, collaborating on human interfaces, user studies, internationalization, ML technologies, system integration, and more., As a Senior Machine Learning Engineer on our team, you will be responsible for the definition, design, and quality of increasingly sophisticated AI features that ship to a global audience. You will drive the development of workflows that facilitate efficient data synthesis, data curation, prompt engineering, and model evaluation. Finally, you will contribute to a company-wide effort to build robust modeling processes that optimize our ability to iterate rapidly and continuously deliver improvements to our customers., * Own the model quality of shipping and unreleased Apple Intelligence features * Prioritize and drive modeling efforts across multiple fronts * Analyze user feedback to understand shortcomings of our models and evaluation data * Define robust evaluation mechanisms to drive data curation, metric calibration, and model hill-climbing * Research state-of-the-art SFT/PEFT/RLHF/distillation techniques for improving model quality and robustness * Implement pipelines, experiments, and simulations to assess the value of modeling changes ## Related Videos - [Introduction to Azure Machine Learning](https://www.wearedevelopers.com/videos/368-introduction-to-azure-machine-learning) - [Your imaginations is (no longer) the limit: how Generative AI empowers people to be creative](https://www.wearedevelopers.com/videos/741-your-imaginations-is-no-longer-the-limit-how-generative-ai-empowers-people-to-be-creative) - [Lessons from Steve Jobs - Learnings from the Past for the Future](https://www.wearedevelopers.com/videos/1021-lessons-from-steve-jobs-learnings-from-the-past-for-the-future) - [Inside the Mind of an LLM](https://www.wearedevelopers.com/videos/1617-inside-the-mind-of-an-llm) - [The shadows that follow the AI generative models](https://www.wearedevelopers.com/videos/624-the-shadows-that-follow-the-ai-generative-models) - [Bringing the power of AI to your application.](https://www.wearedevelopers.com/videos/1010-bringing-the-power-of-ai-to-your-application) ## Related Articles - [What Are Large Language Models?](https://www.wearedevelopers.com/magazine/304-what-are-large-language-models) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [The Best Large Language Models on The Market](https://www.wearedevelopers.com/magazine/319-the-best-large-language-models-on-the-market) - [Got AI ideas but no money?
