The Lead Machine Learning Platform Engineer spearheads development and operationalization of key framework components required in the end-to-end machine learning lifecycle. Using these building blocks, Parks Data and Machine Learning Platform (“the platform”) supports a wide variety of applications in computer vision, natural language processing, data analytics, predictions, recommendations, content creation and optimization. The platform enables multiple studios of developers, data engineers, data scientists, content creators and business analysts across the entire Disney Parks Experiences and Products (DPEP) organization to build, deploy, sustain and continuously improve AI services.

Responsibilities:

  • Lead a team of engineers to design and develop production grade frameworks for feature engineering, model architecture selection, model training, model interpretability, A/B testing, containerization, deployment and feedback.
  • Introduce MLOps tools in conjunction with the existing DataOps and DevOps tools in the platform to facilitate collaboration across diverse user groups within the organization.
  • Create automated self-service procedures that allow the platform to scale across multiple agile projects with minimal overhead.
  • Define SLAs for provisioning and supporting the ML platform services.
  • Integrate tools for optimizing human resource allocation in tasks involving varying degrees of complexity such as labeling, modelling, puppeting.
  • Enforce effective cost optimization techniques in cloud, on-prem, and edge environments to minimize the total cost of ownership of the AI services.
  • Integrate tools for measuring model KPIs, data deviation and drift.
  • Provide bootstrapping templates for the frequently used ML algorithms and pipelines.
  • Build reference implementations to demonstrate use of the platform.
  • Guide delivery studios with accuracy-cost-explainability tradeoffs; create tools to measure them.
  • Create an environment of accountable, auditable, reproducible and ethical AI by providing tools and guidance to business partners.
  • Bring traditional software development best practices (unit/integration testing, documentation, service decoupling) to Machine Learning ops discipline
  • Continually scan the industry and academia for new tools and methods in machine learning. Assist in defining the roadmap and evolution of the platform.
  • Participate in formal/informal discussion forums to simplify and evangelize AI/ML.
