Infrastructure Technician – Operations Centre #2

Salary: H004: $28.05 – $35.00 per hour(based on experience and competencies)


The position of Infrastructure Technician, Operations Centre, is a strategic role with enterprise-wide impact. As the first responder to system problems, interruptions and security breaches; the position is crucial in ensuring the smooth running of all facets of the enterprise, spanning clinical, education, and research. Key responsibilities include monitoring and optimization of IT infrastructure for both users and systems, and ensuring the proper operation of information systems through proactive measures and simple break/fixes. This role is responsible for maintaining the goals of the enterprise from both an infrastructure and security perspective by monitoring, auditing, reporting, repairing, securing, and optimizing systems and services.

As a member of the Operations Centre team, the position is responsible for making sure that Heterogeneity, Interoperability and Utility are met on a centralized large-scale level for all IT infrastructure areas including, but not limited to, data centres, data closets, satellite and partner facilities, and other areas that house a significant amount of IT hardware. Unplanned, no single system can go out of service without direct impact on hundreds of other central systems and many thousands of client systems. The level of integration and interdependency between systems is complex and varied. Uninterrupted operations is a key function of this position.

The day-to-day responsibilities involve over $20 million dollars of central infrastructure and an equivalent amount of endpoint infrastructure. These systems, together, are responsible for data management in real time for patients visiting in clinics, clinical trials and research functions, processing genomic information, operations for hundreds of web sites, databases for general use, the clinical warehouse, UHN biobanking, tens of petabytes of user data, processing farms and utility infrastructure. Due to the interdependencies, an outage of a single service could easily place clinics into a code gray (internal disaster) as normal practice for data gathering would cease. The position is expected to maintain reliability and redundancy in all systems and practices a key point in order to avoid the time and monetary loss that would come with a single hour of outage.

Key responsibilities include monitoring and optimization of the servers, utility servers, storage, network, teleconference equipment, and patient and facility monitoring systems. The specialist is also responsible for monitoring systems for threats from all attack vectors including perimeter and e-mail. The Operations Centre teams are comprised of infrastructure focused and security focused staff where incidents are escalated to L1 or L2 infrastructure or security support staff as required.

To be successful, the candidate will need to develop strong working relationships with team members, so strong interpersonal skills will be a key skillset. The successful candidate will have a strong focus on development in order to continuously increase their own skills as well as mentor other technical resources in the group.

This position works in shift teams having a primary responsibility focused on the central infrastructure and is a backup to the security focused team member. The overall areas that all facets of responsibility fall into are: Unix Infrastructure and Security, Windows Infrastructure and Security (server and endpoint), Network Infrastructure and Security, Perimeter Security, Telephony Infrastructure, Account Infrastructure, Recovery Infrastructure, Audio-Visual Infrastructure, and Database Infrastructure.
