TrakCare, one of InterSystems’ leading healthcare products, has been sold into the UK market since 2009 when we were selected to deliver the Patient Management System that currently underpins the majority of NHS Scotland Hospitals.  In addition to working with several NHS boards in England, TrakcareLab is being rolled out as the LIMS solution supporting all of the Welsh NHS Pathology laboratories.  


In response to growing market demand, InterSystems established a Hosted Services organization in 2015 to enable the delivery of fully managed and hosted TrakCare and other healthcare related solutions.   With two established two data center locations and several contracts in the pipeline, Hosted Services is expected to grow significantly through 2016 and beyond.


In support of this growth, we are now looking for a Senior Managed Services Administrator-Networks to oversee the ongoing delivery, administration and security compliance of the network infrastructure underpinning our hosted services.

  • Monitor and report on network capacity across all network elements, and pro-actively identify and address potential issues in a timely manner.

  • Maintain good relationships with other team members, other teams, customers and suppliers in order to maximize team working and collaboration.
  • Continue to look for ways that the service can be improved and, where agreed, lead or assist with the implementation of service improvements.  In particular, focus on service automation opportunities in line with the wider hosted services strategy and available tools; continue to optimize performance, efficiency and utilization.
