Job description

Network Engineer

Suitland MD, on-site

Occasional coverage in Ashburn VA.

Public Trust required.

Who fills it: ten years in a large federal network environment, six of those in a technical leadership role, real Cisco depth including Nexus 2K/5K/7K and vPC, and hands-on AWS hybrid connectivity. The agency is running a data center lift-and-shift to AWS and this person is the escalation point for it. Direct Connect, Transit Gateway, VPC routing.

The attachment is the JD plus the phone screen guide we use. Please run the screen before submitting. The Nexus and vPC questions and the AWS hybrid question are where this req gets decided. A candidate who cannot walk through an NX-OS upgrade on a vPC pair is not the person, no matter how the resume reads. That is the part that will save us both a week.

• Develops and documents high-level system engineering designs, scope requirements, test cases, standard operating procedures, and implementation plans for both on-prem and AWS-integrated network architectures.
• Presents technical proof-of-concepts and demonstrations to coworkers, management, and the customer, including cloud networking designs and AWS migration approaches.
• Remains available and flexible for production-incident troubleshooting and supports scheduled after-hours and weekend maintenance activities for on-prem and AWS-connected systems.
• Provides training and guidance to junior network and data‑center engineers on hybrid cloud networking fundamentals and AWS connectivity best practices.
• Manages the priorities of the customer's requests and incidents using a proprietary ticketing system while documenting AWS-related tasks and cloud‑migration activities.
