Data Scientist - Operational Intelligence

Business Segment: Direct-to-Consumer (DTC)

Company Description:

Our Direct-to-Consumer (DTC) portfolio is a powerhouse collection of consumer-first brands, supported

by media industry leaders, Comcast, NBCUniversal, and Sky. When you join our team, you'll work across

our dynamic portfolio including Peacock, NOW, Fandango, SkyShowtime, Showmax, and TV Everywhere,

powering streaming across more than 70 countries globally.

And evolution doesn't stop there. With an unequaled scale, our teams make the most out of every

opportunity to collaborate and learn from one another. We're always looking for ways to innovate

faster, accelerate our growth, and consistently offer the very best in the consumer experience. But most

of all, we're backed by a culture of respect. We embrace authenticity and inspire people to thrive.

About the Role:

We are seeking an experienced Data Scientist to join our growing Operational Intelligence team. You will

play a key role in building intelligent systems that help reduce alert noise, detect anomalies, correlate

events, and proactively surface operational insights across our large-scale streaming infrastructure.

You'll work at the intersection of machine learning, observability, and IT operations, collaborating

closely with Platform Engineers, SREs, Incident Managers, Operators and Developers to integrate smart

detection and decision logic directly into our operational workflows.

This role offers a unique opportunity to push the boundaries of AI/ML in large-scale operations. We

welcome curious minds who want to stay ahead of the curve, bring innovative ideas to life, and improve

the reliability of streaming infrastructure that powers millions of users globally.

What You'll Do:

Design and tune machine learning models for event correlation, anomaly detection, alert

scoring, and root cause inference

Engineer features to enrich alerts using service relationships, business context, change history,

and topological data

Apply NLP and ML techniques to classify and structure logs and unstructured alert messages Develop and maintain real-time and batch data pipelines to process alerts, metrics, traces, and

logs

Use Python, SQL, and time-series query languages (e.g., PromQL) to manipulate and analyze

operational data

Collaborate with engineering teams to deploy models via API integrations, automate workflows,

and ensure production readiness

Contribute to the development of self-healing automation, diagnostics, and ML-powered

decision triggersDesign and validate entropy-based prioritization models to reduce alert fatigue and elevate

critical signals

Conduct A/B testing, offline validation, and live performance monitoring of ML models Build and share clear dashboards, visualizations, and reporting views to support SREs, engineers,

and leadership

Participate in incident postmortems, providing ML-driven insights and recommendations for

platform improvements

Collaborate on the design of hybrid ML + rule-based systems to support dynamic correlation and

intelligent alert grouping

Lead and support innovation efforts including POCs, POVs, and exploration of emerging AI/ML

tools and strategies

Demonstrate a proactive, solution-oriented mindset with the ability to navigate ambiguity and

learn quickly

Participate in on-call rotations and provide operational support as needed
