Senior Network Engineer

Position Description

The Network Services Lead will design, modernize, and guide the evolution of highly available, secure enterprise network infrastructure, while supporting the Laboratory’s enterprise classified networks as part of the Digital Solutions Team. This position serves as a senior technical authority for network architecture, establishing technical standards and reference architectures while partnering with network engineers, cybersecurity personnel, system administrators, application teams, and organizational leadership.

The ideal candidate combines strong hands-on technical expertise with an architectural mindset and can translate business, operational, cybersecurity, and compliance requirements into scalable and supportable network designs. The candidate will have a solid background with subnetting, switching, routing, firewall configuration to include managing security zones to limit east/west traffic, configuring and managing TACLANEs and supporting VTC appliances; familiarity with Commercial Solutions for Classified (CSfC) would be a bonus. This candidate will also possess a strong understanding of network automation and virtualization utilizing technologies such as Ansible and VMware NSX. Finally, preference will be given to candidates with experience supporting cloud infrastructure, ideally in classified environments but public experience would also be considered. As part of this role the individual will need to demonstrate proficiency applying STIGs and understanding how to use DISA’s STIG Viewer to evaluate systems for STIG compliance.

This position is 100% dedicated to supporting classified environments and is 100% on-site in Lexington, MA. Occasional off-hour/on-call support is necessary. A certain degree of flexibility of schedule is required as some work (planned/unplanned) must be done outside of major production hours during pre-scheduled maintenance windows.

This position requires an individual with excellent communication (both oral and writing) and organizational skills. The individual must be able to work in a fast-paced environment at times with minimal supervision and execute operations, project and administrative tasks with a high degree of quality, while following existing processes and establishing new operational procedures and best practices where necessary. Additionally, the position requires the ability to work with members of other teams and staff to accomplish department and organizational goals.
