Job Title: Datacenter Architect/Engineer
Duration: 6+ Months
Location: REMOTE (Occasional travel to NJ)
Note: This is a 6 month project that will require managing change windows in the data center during weekends. We expect at least 1 weekend per month for each engineer and potentially 2 weekends per month. This is remote work with occasional travel to NJ. Preferred resources are in EST, and proximity to NJ ideal. Target is to manage the hours so that resources are working 40 hours per week.
Currently, data centers in Raritan, NJ and Ashburn, VA have two (2) primary network topologies; a traditional multi-tier network design and a newer spine/leaf design. The goal of this project is collapse existing zones from within the traditional multi-tier architecture to leaves on the spine/leaf architecture. At the time of writing there are approximately thirty-one (31) zones defined in Raritan and tagged by network architecture team with the following target dispositions: nine (9) retirements, fifteen (15) transformations, and seven (7) migrations. In Ashburn there are eleven (11) zones tagged with the following target dispositions: two (2) retirements; seven (7) transformation; and two (2) migrations for consideration under this SOW.
The project is expected to break down into two phases where phase one will last approximately two months and phase two will continue until December 31, 2019. In phase one of the project, will work alongside the Customer team to perform discovery and evaluation to determine a high level design (HLD) to migrate, transform, or retire zones. In the first month of phase one a Solution Architect and Network Design/Implementation Engineer will begin HLD work with the customer team as well as work with the program manager and customer team to begin prioritization of zones for further assignment. Formalization of program governance and documentation standards and team procedures will also occur at this time. In week four, three additional Network Design/Implementation Engineers will be onboarded to join the team for the second month of phase one. In the second month of phase one, HLD work will continue, prioritization will be refined and the development of a “t-minus” schedule to target and track progress will occur. LLD work and implementation may also begin. In phase two of the project, both will work to finalize remaining HLD work, create LLDs and implementation plans, execute implementation procedures to transform zones, complete documentation and knowledge transfer activities, and manage ongoing work streams.
Analysis and Design
Data gathering to define current state to develop a high-level design document that will determine future state.
