The Network Engineer III is responsible for the overall design, configuration and troubleshooting of the most complex IT systems in the enterprise data centers as well as intercampus connectivity that impact mission critical enterprise academic, medical and research systems and application services. This position will be heavily involved in network virtualization and hybrid cloud technologies. This position will design, build and support virtual network connectivity Examples of the hundreds of systems the engineer III will architect the network solutions for are SAP, Blackboard, ISIS, EPIC, Exchange, EPR, anycast DNS and DHCP. These applications consist of a multi-tiered architecture of firewalls and load balancers to achieve the highest performance, availability and security model possible. This position requires an advanced understanding of the entire OSI model. This position requires advanced knowledge of BGP and MPLS to architect ISP solutions for the enterprise, which today includes 3 Tier I commodity internet providers and Internet 2. This position requires expert knowledge of network engineering in regards to routing, switching, application performance, load balancing and intermediate to expert knowledge in systems management, all server operating systems and application design.
Position primarily focuses on moderately complex to highly complex designs for data and voice communication systems throughout the Johns Hopkins enterprise. This position is the highest level network engineering position in the job family and assignments will typically involve engineering services for the entire Johns Hopkins enterprise, such as configuring/installing Internet Service Provider links, Internet2 services, engineering DWDM/Optical solutions, engineering routing solutions that span multiple campuses, and complex configuration changes that could be customer impactful across the entire enterprise (all Johns Hopkins entities: EB, BV, HW, Eastern, Keswick, Sibley, Howard County General, Suburban, APL, etc.). Position will engineer very complex designs that involve a multitude of variables, multiple vendors, and a broad customer base. Job complexity includes design/engineering/installation and overseeing large scale projects (campus wide and enterprise wide), troubleshooting complex routing and switching protocol issues, and interfacing with customers to understand needs. Typically, this job is focused on several Johns Hopkins campuses; however this position is expected to travel throughout Maryland/DC to cover any Johns Hopkins location as required.
The responsibilities listed below are typical examples of the work performed by this position. Not all duties assigned to this position are included, nor is it expected that everyone in this position will be assigned every job responsibility.
