O projekcie, The Role, , As a Backend Engineer at our client, you will contribute directly to the core index layer, processing video indexing based on signals from the algorithm team. Your work will power the auto-tagging engine—the system that splits sports games into distinct events and accurately assigns start and end times to each action. You will balance deep feature development with critical problem-solving in a highly collaborative, AI-integrated environment., , About the Product, , The product is an AI-powered sports media platform used by major sports organizations to transform live broadcasts into personalized digital content at scale. Every live stream is continuously ingested, analyzed, and enriched with AI-generated metadata, enabling automatic detection of key moments, intelligent video indexing, and near real-time content creation., , Behind the scenes, the platform processes massive volumes of live and archived video 24/7, powering personalized fan experiences across web, mobile, social, and broadcast channels. The backend infrastructure is built for extreme throughput, low-latency processing, and elastic scaling, combining distributed microservices with production-grade ML inference pipelines to deliver reliable performance under unpredictable traffic peaks., , Team Structure & Collaboration, , You will join a focused backend squad consisting of four developers, one QA, and one PM, led by the engineering manager. This squad sits within a larger group of two backend teams and two algorithm teams. Because the index layer relies heavily on algorithm signals, you will work in close daily collaboration with the AI and algorithm teams., , Why This Role Is Worth Your Time, , Direct ownership of pure backend compute at scale—no full-stack dilution, focusing entirely on high-load microservices, indexing engines, and real-time processing, High-autonomy environment with modern workflows where AI tools (Claude, Cursor) are embraced to eliminate boilerplate and keep focus on architecture,
