Callum Owen

Contribution Engineer

Responsible for design, integration, and delivery of cloud and software-based broadcast contribution systems for TNT Sports and Eurosport across EMEA, providing tier 3 support and leading automation development to increase network efficiency and performance

• Developed tooling to automate configuration and management of 500+ software encoders with React, Node.js and Postgres, reducing operational overhead for UEFA Champions League and Paris 2024 Olympics, notably reaching a record 215M viewers
• Architected dynamic multi-region hybrid cloud infrastructure using AWS Direct Connect and advanced VPC routing, automating the scaling of EC2-based encoders to meet fluctuating live broadcast demands with resilient failover mechanisms
• Orchestrated cloud migration of legacy on-prem SRT workflows, building automated CI/CD pipelines to deploy containerised encoders onto AWS ECS, expanding concurrency while reducing physical colocation footprint to save £millions in CapEx
• Owned and managed multifaceted technical projects, collaborating with colleagues and third-party stakeholders through effective communication and accountability across Jira, agile ceremonies, and scrum meetings
• Optimised stream performance following rigorous A/B testing of architectural solutions, conducting statistical analysis of AV Sync, Video Latency, and 2022-7 Hitless metrics to inform critical management decisions
• Developed monitoring dashboards and automations using Python, Grafana, CloudWatch, DataMiner, and Lambda to handle ETR290 alarms (TS Sync Loss, CC Errors, Memory Usage) to diagnose and resolve critical transport faults, maintaining uptime
