The product is an AI-powered sports media platform used by major sports organizations to transform live broadcasts into personalized digital content at scale. It processes massive volumes of live and archived video 24/7, powering personalized fan experiences across web, mobile, social, and broadcast channels with a backend infrastructure designed for extreme throughput, low-latency processing, and elastic scaling.

• 5+ years of experience building and scaling high-throughput backend systems in cloud/SaaS environments
• Proven expertise in a mainstream backend language (such as C#, Java, or Python) with strong distributed systems principles
• Hands-on experience designing relational SQL schemas and optimizing complex data access patterns
• Practical experience with pub-sub and event-driven messaging systems (Kafka, Azure ServiceBus, or equivalent)
• Track record of leveraging CI/CD pipelines and AI-assisted engineering tools (Claude, Cursor) in daily workflows
• Degree in CS/Software Engineering or equivalent real-world depth

Nice to have:

• Production experience with .NET Core within a large microservices estate
• Deep cloud platform experience (Azure hyperscaler, networking, cost/performance trade-offs)
• Background handling asynchronous batch processing or high-scale ML model deployment pipelines

• Own the video-analysis pipeline and auto-tagging engine, driving end-to-end performance from architectural design to production operation
• Integrate ML and AI inference models into backend services to handle automated real-time video indexing
• Redesign backend microservices and APIs to improve throughput, latency, and resource utilization during peak traffic surges
• Implement pub-sub event architectures using Kafka or ServiceBus to process video streams asynchronously
• Establish system observability, runbooks, and incident response tooling to ensure 24/7 uptime for critical backend services
• Mentor backend engineers, drive code review standards, and lead technical design across 30+ active microservices
