Reach, Scale & Impact: More than ever, Disney’s technology and products serve as a signature doorway for fans’ connections with the company’s brands and stories. Disney+. Hulu. ESPN. ABC. ABC News…and many more. These products and brands – and the unmatched stories, storytellers, and events they carry – matter to millions of people globally. Innovation: We develop and implement groundbreaking products and techniques that shape industry norms and solve complex and distinctive technical problems. Product Engineering is a unified team responsible for the engineering of Disney Entertainment & ESPN digital and streaming products and platforms. This includes product engineering, media engineering, quality assurance, engineering behind personalization, commerce, lifecycle, and identity. The Observability & Insights group ensures that Disney Streaming’s distributed systems are reliable, performant, and transparent. We build ML-powered detection systems, telemetry pipelines, intelligent alerting, and developer experience tooling that enable engineers across the organization to understand system health and take action quickly. Job Summary: As a Software Engineer II, you will contribute to building and operating machine learning models and AI-driven systems that enhance the reliability of Disney’s streaming ecosystem. You will work on production ML models — including autoencoders for anomaly detection, statistical threshold systems, and LLM-powered investigation gates — that transform telemetry and signals into automated detection and proactive insights across Disney+, Hulu, and ESPN. You will participate in the ML lifecycle: feature engineering on time-series data, model training on GPU clusters, real-time inference pipelines, and model improvement. You will partner with engineering and platform teams to embed intelligence into operational workflows, improving system resilience and customer experience at scale. As a Software Engineer II, you will deliver features end-to-end, participate in model design and code reviews, and grow into owning components of production ML systems within a fast-paced, AI-native engineering environment. Responsibilities and Duties of the Role: Contribute to production ML models for anomaly detection, including autoencoders, statistical threshold models, and ensemble detection systems that monitor thousands of microservices Develop and improve ML training pipelines using PyTorch on GPU clusters — including feature engineering, model training, threshold calibration, and deployment through MLflow Engineer features from time-series telemetry (error ratios, latency, infrastructure metrics) — implementing windowing, normalization, and data quality safeguards for model consumption Support real-time ML inference systems that run prediction cycles in production — including model serving, detection logic, and alert generation Build AI-driven capabilities using foundation models (Claude, GPT-4) for automated investigation and reasoning over system health signals Create and deploy scalable APIs and services (FastAPI) that deliver ML predictions, health status, and insights to engineering teams and operational tooling Partner cross-functionally to embed ML intelligence into workflows such as incident response and release validation Contribute to model improvement through evaluation, retraining, and threshold tuning Basic Qualifications 3+ years of professional software engineering experience building, scaling, and maintaining ML-powered backends, data-driven microservices, and production RESTful APIs using FastAPI or Flask Strong hands-on experience in end-to-end ML engineering using PyTorch or TensorFlow spanning model architecture selection, feature engineering, training, and evaluation (e.g., autoencoders, sequential/time-series models like RNNs/GRUs, anomaly detection, or transformers). Proficiency in Python and at least one ML framework (PyTorch preferred) Experience managing model experiments, lineage, and hyperparameter tracking using tools like MLflow or Weights & Biases. Practical experience processing, transforming, and querying large-scale telemetry, event, or time-series datasets using PySpark, Pandas, or Databricks. Experience with modern development practices including version control (GitHub), containerization (Docker), and cloud-native deployments (AWS/EKS) Strong analytical and troubleshooting skills with the ability to iterate rapidly Strong collaboration and communication skills, with the ability to work cross-functionally Preferred Qualifications Experience with foundation model integration, prompt engineering/evaluation, RAG architectures, or orchestration frameworks like LangChain or LangGraph Familiarity with observability platforms (e.g., Datadog, Grafana, Conviva) and high-volume telemetry data Experience with large-scale data platforms (Databricks, Spark, Snowflake) Required Education Bachelor’s degree in Computer Science, Machine Learning, Statistics, Engineering, or equivalent experience #disneytechThe hiring range for this position in Glendale, CA is $117,500 - $157,500 per year, and in New York City, NY is $123,000 - $165,000 per year.
