IT Service Specialist- Platforms IBM
The Infrastructure Platforms team manages all server-related infrastructure and hardware within the datacentres in Clarks, including virtualisation, storage, compute, backup and recovery. We now have an excellent opportunity for someone keen to get experience in a broad range of systems and services. In larger companies, there’s often a narrower focus, but working in the small team we have in Clarks means the role has accountability for many technologies.
What You'll Do
Day-to-day activities can vary from remote management of operating systems, performance monitoring and tuning, troubleshooting (often with broad involvement from multiple teams and including out-of-hours support), hardware replacement and maintenance of storage appliances, cabling, and firmware updates. Each day can be very different.
This role requires a minimum of 3 days a week in the office. The broader infrastructure team is small, and as such, interaction between other team members while troubleshooting is critical.
Requirement for out-of-hours support as needed and for hands-on support where needed. As the data centres and hardware are UK-based, travel at short notice may be necessary to meet the requirements of the role.
