Network Architecture & Design

We evaluate your ability to design scalable, fault-tolerant systems. Strong candidates can articulate how to build networks that account for redundancy and future growth.

• Routing Protocols – Deep knowledge of OSPF, BGP, and EIGRP.
• Switching – Proficiency in VLAN management, spanning-tree protocols, and link aggregation.
• Infrastructure Automation – Experience with scripting or tools that streamline network configuration.

As a Network Engineer, you will be responsible for the end-to-end lifecycle of our networking infrastructure. This includes the design, deployment, and ongoing maintenance of hardware and software solutions that support our operations. You will spend a significant portion of your time monitoring system health, implementing security patches, and refining network topology to meet evolving mission requirements.

You will frequently collaborate with systems administrators and security analysts to ensure that network changes do not compromise existing security postures. Whether you are leading a major infrastructure migration or performing routine maintenance, your work will be defined by a commitment to precision, documentation, and operational excellence.

We seek engineers who possess a blend of formal technical training and hands-on experience in secure environments.

• Must-have skills – Expert knowledge of routing and switching, experience with enterprise-grade network hardware, and a valid TS/SCI with Polygraph.
• Nice-to-have skills – Experience with software-defined networking (SDN), familiarity with cloud networking architectures, and certifications such as CCNP or CCIE.
• Experience level – We hire across a spectrum from Junior to Principal/Lead. Your compensation and scope of responsibility will be commensurate with your years of experience and demonstrated expertise in the field.

Q: How long does the hiring process typically take? A: Due to the high-security nature of the role and the necessary clearance verification, the process can take longer than standard roles. We recommend starting your preparation as soon as you apply.

Q: What differentiates a successful candidate? A: Successful candidates don't just know the protocols; they understand how those protocols behave at scale and how to secure them against sophisticated threats.

Q: Is this a remote role? A: Given the nature of the work and the requirement for a TS/SCI with Polygraph, this position is based in Vienna, VA, and requires on-site presence.

• Articulate your process: When answering technical questions, explain your thought process out loud. We are as interested in how you approach a problem as we are in the final answer.
• Review your resume: Be ready to speak in detail about every project listed on your resume, specifically regarding your personal contribution and the technical hurdles you overcame.
• Stay current: Review recent advancements in network security and automation to show you are proactive in your professional development.
