Network Engineer, Senior

Network Engineer, Senior A well‑designed network is critical to move data and enable the Department of Defense (DoD) to achieve their missions, but how can an organization make sure their network will fit their evolving needs? Crafting the right network, with the right equipment and software, requires a combination of technical skill and careful planning. That’s why we need a seasoned Network Engineer who knows how to develop the exact network the DoD needs. As a Network Engineer on our team, you’ll use your experience in network design and architecture, system interoperability, OSI model, network transport layers, multi‑protocol label switching, gateway protocol, and virtual routing and forwarding to support the nation’s defense. You’ll develop enterprise‑wide infrastructure design, troubleshoot and resolve complex network issues, analyze current working infrastructures, and increase security, reliability, and availability for mission‑critical network systems. You’ll apply your expertise in routing and switching, network design and architecture, system interoperability, IP engineering, and more as you guide our team of problem‑solvers to help the DoD evolve and deploy new capabilities and technologies. Using your experience in software and hardware firewalls, Cisco, Palo Alto, Juniper, and optical infrastructure networking, you’ll serve as a trusted advisor to clients on mission‑critical projects and make an impact on national security missions. Roles and Responsibilities • Develop enterprise‑wide network infrastructure designs and architectures for DoD hybrid environments. • Troubleshoot and resolve complex network issues, ensuring security, reliability, and availability. • Design and implement advanced routing solutions (e.g., BGP AS_PATH loop prevention, max‑prefix route‑limit protection). • Document complex network and security architectures, procedures, and troubleshooting workflows, including Zero Trust Network Access implementations. • Act as a trusted advisor to clients on mission‑critical projects, leveraging expertise in firewalls, routing, and optical networking. You Have: 5+ years of experience designing, deploying, and supporting network and security architectures within DoD hybrid environments, including implementing Zero Trust principles and advanced routing designs, such as BGP AS_PATH loop prevention and max‑prefix route‑limit protection. 2+ years of experience with implementing and configuring network segmentation or micro‑segmentation solutions, including Software‑Defined Networking (SDN) technologies, container networking, and virtualization platforms. 2+ years of experience documenting complex network and security architectures, procedures, and troubleshooting workflows, including Zero Trust Network Access (ZTNA) implementations and detailed documentation of BGP policy behavior, NGFW IDS or IPS configurations, or NAT or SNAT translation flows. Experience designing and architecting enterprise network and cybersecurity solutions within DoD hybrid environments, including applying NGFW capabilities or building resilient routing architectures using BGP operational safeguards. Experience supporting defense programs, standards, or mission requirements directly or indirectly, including Zero Trust initiatives that rely on correct traffic segmentation, NAT or SNAT translation for external communication, and IPS‑based enforcement. Experience working with secret classified networks, including the unique security challenges and requirements of these environments within a ZTNA model, such as proper routing controls, segmentation boundaries, or inline IDS or IPS visibility. Knowledge of DoD security standards and compliance requirements in a Zero Trust Network Access model. Secret clearance. HS diploma or GED. Nice If You Have: Experience supporting and operating DoD networks. Experience deploying, upgrading, and troubleshooting multi‑vendor network and security platforms, such as Palo Alto, Cisco, Juniper, Dell, HPE, and VMware. Experience administering Linux and Unix systems in enterprise or tactical environments. Experience applying STIGs and performing system security hardening. Experience administering Windows systems and services. Experience with commercial and DoD cloud networks. Knowledge of IDS (detect and alert) and IPS (block and drop) operations. Bachelor’s degree in CS, Engineering, or a related field. CCNA, CCNP, VMware, JNCIA, or JNCP Certification. Clearance: Applicants selected will be subject to a security investigation and may need to meet eligibility requirements for access to classified information; Secret clearance is required. Compensation and Benefits Salary range: $77,600.00 to $176,000.00 (annualized USD). Compensation is determined by location, education, skills, and organizational requirements. In addition, Booz Allen offers a comprehensive benefits package that includes health, life, disability, financial, and retirement benefits, paid leave, professional development, tuition assistance, work‑life programs, and dependent care. Full‑time and part‑time employees working at least 20 hours a week on a regular basis are eligible for the benefit programs. Commitment to Non‑Discrimination All qualified applicants will receive consideration for employment without regard to disability, status as a protected veteran or any other status protected by applicable federal, state, local, or international law. #J-18808-Ljbffr
