Software Development Engineer II (Backend) - Viewer Experience

Job Summary: As an SDE-II, you’ll build backend systems that power the most critical moments in a user’s journey — from opening the app, to experiencing personalized, dynamic content, to experiencing. Your primary focus will be on scaling our platform infrastructure, architecting a state-of-the-art compositor engine, and evolving a multi-widget, server-driven layout system that constructs rich, adaptive pages across all devices. You’ll help ensure that hundreds of millions of users enjoy fast, seamless, and always-on experiences, no matter the time, traffic, or device.

About the team: At JioHotstar, the Viewer Experience (VX) org is at the heart of how millions discover, engage with, and fall in love with our platform.

If you're passionate about building immersive, intelligent, and performant user experiences that delight a billion users, join us in shaping the future of streaming.

Key responsibilities:

• Own scale-critical paths, ensuring the system can handle peak concurrency, multi-region delivery, and freshness guarantees
• Build the infrastructure & capabilities that serves as the orchestration layer between downstream services and client apps — enabling faster experimentation, seamless rollouts, that works for every device & platform out there
• Develop the Compositor Engine that fetches and ranks content blocks (widgets/cards), merges metadata, and serves highly contextualized page definitions to clients in milliseconds
• Collaborate with Product, Data Science, and Frontend teams on use cases like personalized feeds, layouts, and dynamic page composition
• Improve latency, throughput, and observability across all surfaces where UI is driven from the server — including Homepage, Watch pages, and Detail views

• Participate in design discussions, code reviews, and on-call rotations, maintaining high service reliability even during peak traffic
• Continuously evaluate relevant technologies and influence architecture and design discussions Guides and mentors juniors on functional attributes and domain knowledge

Skills and attributes for success:

• Strong coding skills (Golang)
