About the role

Key responsibilities & impact

Design and lead test strategies for streaming workflows, playback systems, and AI-powered features.
Test across platforms (web, mobile, and connected TV) to ensure functional parity and playback stability.
Validate streaming performance—including ABR logic, encoding pipelines, and DRM integrations—under diverse real-world conditions.
Debug with precision using tools like Charles Proxy, Chrome DevTools, ADB, and Xcode. Collaborate with data and ML teams to validate AI model updates, recommendations, and personalization accuracy.
Leverage AI-assisted QA tools to enhance regression coverage, UI validation, and anomaly detection.
Contribute to automation and CI/CD frameworks, driving faster, more reliable releases.
Help drive a shift-left testing approach by engaging early in the software development lifecycle, partnering with product managers, engineers, and data scientists to identify quality risks, define test strategies, and ensure testability during requirements and design phases.
Oversee QA deliverables for multiple concurrent releases and ensure seamless sign-off for production launches.
Monitor live environments for playback or recommendation anomalies post-release and escalate issues promptly.
Continuously improve QA processes, metrics, and reporting for streaming and AI validation.
