Machine Learning Engineer, Wallet Intelligence and Machine Learning

Apple Apple · Big Tech · Austin, TX +2 · Machine Learning and AI

Machine Learning Engineer for Apple's Wallet Intelligence and Machine Learning team, focusing on on-device fraud detection models for Apple Pay and Apple Wallet. The role involves end-to-end ownership of ML solutions, from problem framing to deployment, with a strong emphasis on privacy, real-time performance, and resource constraints.

What you'd actually do

  1. Take end-to-end responsibility for translating customer and security needs into machine learning solutions, from framing the problem through feature engineering, model development, training, evaluation, and reporting.
  2. Design and deliver models that operate within real-world constraints, balancing accuracy against latency, model size, and on-device compute budgets so that protection never comes at the cost of the user experience.
  3. Build and share a system-wide understanding of where our models fit into the user journey and the fraud-risk journey, and use that understanding to anticipate problems rather than react to them.
  4. Uphold and advance a high standard for user privacy in everything you build.
  5. Partner across software engineering, security, program management, and business teams to define problems, align on solutions, and communicate results clearly to both technical and non-technical audiences.

Skills

Required

  • Experience with machine learning methods such as classification, clustering, and anomaly detection.
  • Strong programming skills in one or more languages such as Python, Scala, or Java.
  • Experience processing and analyzing data at scale using distributed data or compute frameworks.
  • Ability to communicate the results of analysis clearly and succinctly to a range of audiences.
  • Experience delivering results on ambiguous, loosely defined problems, working with others.
  • Rigorous analytical thinking, including the ability to question assumptions, reason through a problem, and justify a recommendation with sound evidence.

Nice to have

  • Experience deploying machine learning in resource-constrained or real-time environments, such as on-device deployment, model compression, or optimizing for inference budgets.
  • Experience with distributed data and compute frameworks such as Spark, Ray, or Daft.
  • Familiarity with privacy-preserving machine learning techniques.
  • Background in fraud detection, risk modeling, or security-focused machine learning.
  • Familiarity with iOS development.
