Machine Learning Engineer (Applied Machine Learning), AI & Data Platforms (AiDP) in London

At Apple, we’re building the next generation of AI systems that power experiences for billions of users worldwide. The AI & Data Platforms (AiDP) team is seeking an ML Engineer to architect and deploy production‑scale generative AI systems that balance innovation with Apple’s uncompromising standards for privacy, performance, and quality. The successful candidate will own end‑to‑end ML initiatives, from problem framing and experimentation to production deployment and measurable business impact. If you’re passionate about transforming research into robust ML infrastructure and solving complex engineering challenges at the intersection of GenAI and distributed systems, we want to hear from you.

Our Machine Learning Engineers work on building intelligent systems to democratize AI across a wide range of solutions within Apple. You will drive the development and deployment of AI models and systems that directly impact the capabilities and performance of Apple’s products and services. You will implement robust, scalable ML infrastructure, including data storage, processing, and model serving components, to support seamless integration of AI/ML models into production environments. You are a creative problem solver with strong ML and engineering skills who will implement automated ML pipelines for data preprocessing, feature engineering, model training, hyper‑parameter tuning, and model evaluation, enabling rapid experimentation and iteration.

Responsibilities

• Design and deploy production ML/GenAI systems that drive measurable business outcomes across Apple’s product ecosystem.
• Build next‑generation infrastructure leveraging distributed systems, hardware acceleration, and optimization techniques.
• Partner with cross‑functional teams to translate groundbreaking research into user‑centric products.
• Solve uniquely challenging problems in privacy‑preserving ML and efficient inference at scale.
• Champion ML engineering excellence through robust testing, monitoring, and documentation that meets Apple’s quality bar.

Minimum Qualifications

• Bachelor of Science in Machine Learning, Data Science, Computer Science or a related quantitative field or equivalent experience.
• Demonstrated experience in Machine Learning engineering with solid experience in Python.
• Hands‑on experience with LLMs and generative AI systems (e.g. RAG, prompt engineering, evaluation) as well as agentic frameworks.
• Experience building enterprise‑grade ML pipelines (data prep, distributed training, optimisation, monitoring) in cloud environments (AWS, GCP, Azure) or on‑prem infrastructure.

Preferred Qualifications

• Contributions to major open‑source ML frameworks or research communities.
• MS in Computer Science, Machine Learning, or a related quantitative field.
• Solid grasp of NLP techniques, multimodal AI (text, image, code), and agent workflows.
• Experience with LLM agentic workflows and frameworks (Langchain, LangGraph, DSPy, or similar).
• Experience applying core data science methods such as anomaly detection, forecasting, clustering, and pattern discovery — and translating those insights into impact.
• Familiarity with performance optimisation for ML workloads (hardware acceleration, inference tuning).
• Familiarity with designing data pipelines and producing aggregated datasets.

At Apple, we’re not all the same. And that’s our greatest strength. We draw on the differences in who we are, what we’ve experienced and how we think. Because to create products that serve everyone, we believe in including everyone. Therefore, we are committed to treating all applicants fairly and equally. As a registered Disability Confident employer, we will work with applicants to make any reasonable accommodations. Apple will consider for employment all qualified applicants with criminal backgrounds in a manner consistent with applicable law.
