• Partnering with program leadership to deliver updates, insights, and recommendations

• Implementing network changes and optimizations to improve performance and reliability

• Collaborating with Tier 3 engineering on deployment changes for production network devices

• Staying current on emerging technologies and best practices in networking and communications

This is a hands‑on, high‑impact role where your expertise directly strengthens mission operations.

You bring a strong technical foundation, operational awareness, and the ability to lead others through complex network challenges.

• Active DoD TS/SCI clearance

• Current DoD 8140‑compliant security certification (IAT/IAM Level III equivalent)

• Ability to obtain required computing environment certification within 6 months

• At least 6 years of networking experience, with a focus on Juniper and Cisco systems

• Strong understanding of TCP/IP, IP addressing, and subnetting

• Experience troubleshooting network issues across LAN and large WAN environments, including firewalls and network taps

• Proficiency with tools such as iPerf and Wireshark

• Strong troubleshooting skills and the ability to respond quickly to real‑time dataflow issues

• Proficiency with Microsoft Office Suite (Word, Excel, PowerPoint, Visio)

• Excellent written and verbal communication skills

• Proven ability to support complex technical environments

• Strong interpersonal skills and the ability to collaborate with leadership and cross‑functional teams

• Demonstrated ability to train and mentor personnel in technical and operational domains

These skills will help you stand out:

• Industry certifications (Juniper, Cisco CCNA/CCNP, etc.)

• Experience configuring and optimizing Juniper Session Smart Routers

• Experience with TACLANEs and network encryption devices

• Familiarity with mission‑environment operational support procedures

You’ll be a critical part of a team that keeps mission‑essential networks running at peak performance.
