Senior Machine Learning Engineer

ESPN is investing in large-scale data infrastructure and real-time processing platforms that power next-generation personalization and live sports experiences. As a Machine Learning Engineer, you will focus on building and operating distributed data and ML infrastructure that supports high-throughput, low-latency data processing and real-time ML use cases.

In this role, you will work closely with senior MLEs, data engineers, platform/SRE, and product teams to develop streaming data pipelines, feature computation systems, and ML-adjacent services that operate reliably at scale. The role emphasizes hands-on engineering, strong fundamentals in distributed systems, and practical experience operating production data infrastructure.

Responsibilities and Duties of the Role:

1. Large-Scale Data Processing & Streaming Systems

• Build and maintain high-throughput batch and streaming data pipelines to support ML, analytics, and real-time decisioning use cases.
• Implement data ingestion, enrichment, aggregation, and transformation workflows using modern distributed data frameworks.
• Ensure pipelines meet latency, reliability, and data quality requirements for downstream ML and product teams.

2. Real-Time Data & Feature Infrastructure

• Develop and operate systems that support real-time feature computation and delivery for online ML services.
• Work with feature stores and event-driven architectures to ensure consistency between offline and online data.
• Improve data freshness, schema evolution, and backward compatibility in streaming environments.

3. ML-Adjacent infrastructure & Platform Engineering

• Build and operate ML-adjacent services such as inference inputs, feature APIs, and data access layers.
• Contribute to scalable service patterns including autoscaling, rollout strategies, and resiliency mechanisms.
• Partner with platform/SRE teams to improve system availability, performance, and cost efficiency.

4. Reliability, Observability & Operations

• Instrument data and ML infrastructure with metrics, logging, and alerting to support production operations.
• Participate in on-call rotations and incident response for data and ML platforms.
• Identify and remediate data pipeline failures, performance regressions, and operational risks.

3. Collaboration & Engineering Execution

• Collaborate with applied ML and data science teams to enable production ML workflows through reliable data systems.
• Participate in design reviews, code reviews, and technical discussions.
• Follow established platform standards and contribute incremental improvements over time

• Experience building and operating large-scale data or ML systems in production.
• Strong fundamentals in distributed systems and data processing architectures.
• Hands-on experience with streaming and batch data technologies (e.g., Kafka, Kinesis, Spark, Flink, or equivalent).
• Proficiency in Python and working knowledge of Java, Scala, Go, or C++.
• Experience operating systems in cloud-native environments (AWS, containers, Kubernetes, IaC tools).
• Familiarity with observability and operational best practices for production systems.
• Strong collaboration skills and ability to work effectively across engineering and data teams

Preferred qualification:

• Experience supporting real-time personalization, recommendation, or analytics systems.
• Familiarity with feature stores, event-driven architectures, and real-time ML pipelines.
• Exposure to ML infrastructure concepts such as inference pipelines, data validation, and model lifecycle tooling.
• Experience optimizing data systems for latency, throughput, and cost efficiency.
• Understanding of experimentation platforms and data instrumentation for online systems.

Experience with:

• 5+ years of industry experience building data-intensive or ML-adjacent systems in production

Required Education

• Bachelor's or Master's degree in Computer Science, Data Engineering, Machine Learning, or a related field
