TL;DR · Senior Machine Learning iOS Platform Engineer, Responsible AI and Safety

The Senior Machine Learning iOS Platform Engineer — Responsible AI and Safety joins the team leading Responsible AI initiatives for global generative AI products. This role involves owning the integration of Responsible AI mitigation assets across the full deployment surface, including on-device foundation models on Apple Silicon and server-side inference on Private Cloud Compute. You will lead the architectural vision and implementation of safety classifiers, guardrail models, and mitigation policies. Key responsibilities include defining multimodal workflows, optimizing for large-scale image processing, and mentoring engineers. Required skills include 12+ years of experience with Objective C and Swift, expertise in Core iOS and Foundation frameworks, and knowledge of Core ML or MLX. You will solve technical problems regarding model-export lifecycles, token-streaming inference, and real-time safety enforcement.

What you'll do

  • Define and evolve the technical architecture for complex multimodal workflows to ensure scalability and performance.
  • Integrate Responsible AI mitigation assets across on-device foundation models and server-side inference.
  • Design and implement safety classifiers, content filters, and policy enforcement layers for generative AI.
  • Optimize features for large-scale image processing and real-time interactions to meet high performance standards.
  • Develop and maintain deployment pipelines, tooling, and frameworks for monitoring and diagnosing model failures.
  • Convert trained models into shippable assets and manage efficient loading at runtime using on-device ML runtimes.
  • Implement token-streaming inference, tokenization, and buffering strategies for frontier LLM models.

What we're looking for

  • 12+ years of professional experience.
  • 5+ years of experience in iOS / macOS application development in both Objective C and Swift.
  • Expertise in Apple's Core iOS and Foundation frameworks.
  • BS in Computer Science, Mathematics, Statistics, or a related field, or equivalent industry experience.
  • Experience in shipping impactful mobile frameworks used by others outside your direct team.
  • Experience leading the architecture and development of complex, high-performance production systems.
  • Demonstrated ability to technically lead projects, mentor engineers, and drive cross-functional initiatives from concept to delivery.
  • Working knowledge of on-device ML runtimes, model-export lifecycles, and frontier/LLM models (preferred).
