NATURE OF WORK

A Department of Information Technology (DoIT) Network Operations Specialist II is the full performance level of work in the Office of Security Management (OSM) and is tasked with day-to-day management of the firewalls and other network-based components that support security operations.

Employees in this classification receive general supervision from the Director of Security Operations or another designated administrator.  Positions in this classification do not supervise. 

Positions in this classification are evaluated using the Classification job evaluation methodology. The use of this method involves comparing the assigned duties and responsibilities of a position to the job criteria found in the Nature of Work and Examples of Work sections of a class specification. 

This position may require work outside of regular business hours, and work in an on-call capacity. 

The DoIT Network Operations Specialist I and the DoIT Network Operations Specialist II are differentiated on the basis of supervisory control exercised by the supervisor over these employees.  The DoIT Network Operations Specialist I performs a limited range of duties under moderate supervision and the DoIT Network Operations Specialist II performs the full range of duties under general supervision. The DoIT Network Operations Specialist II differs from the DoIT Network Operations Specialist Lead/Advanced in that the DoIT Network Operations Specialist Lead/Advanced serves as a project lead or addresses the most complex tasks and escalated issues prior to engaging a higher-level IT manager or director or leads lower-level DoIT Network Operations Specialists.
