Platform Engineer

Roles and Responsibilities

• Design, build, tune and maintain the server, storage, network and virtualisation infrastructure that underpins the video delivery platform, ensuring optimal utilisation of system resources (CPU, memory, IOPS, network).
• Profile and performance-tune the platform and its SOA applications – identifying and eliminating bottlenecks across the OS, kernel, network and storage layers to meet carrier-grade performance and scalability targets.
• Fine-tune network and kernel parameters on Linux based systems to achieve high throughput and low latency for large-scale content delivery.
• Deploy, configure, operate and troubleshoot distributed storage and database clusters (Ceph and Cassandra), ensuring data durability, availability and performance at scale.
• Automate provisioning, configuration, deployment and routine operational tasks using Python and Ansible to improve repeatability, reliability and speed of delivery.
• Deploy and manage workloads across public cloud (AWS) and virtualised environments (OpenStack, Linux KVM, VMware), including the migration of applications onto cloud architectures.
• Improve the resilience and high availability of the platform through capacity planning, fault-tolerance design and fault-injection / chaos testing.
• Set up and maintain monitoring, alerting and observability, and take part in incident response and root-cause analysis to keep production systems healthy.
• Collaborate with Development, QA and Product teams to define and validate non-functional requirements (performance, scalability, reliability), and document infrastructure architecture, tuning guidelines and operational runbooks.
• Analysing and Fixing Platform related field issues
