Job Description
The Work
What Success Looks Like
- Incidents get resolved without a second escalation to establish who owns the problem.
- Recurring failures get traced to a root cause and closed, rather than reset and re-reported a week later.
- You can tell a non-technical operator what happened and when it will be fixed, in terms they can act on.
- Changes you make hold up under continuous operational load, not just in the maintenance window.
- Refresh and redesign work lands inside approved windows and does not run past them.
- Designs account for the sites that are hardest to reach and hardest to take down, not only the convenient ones.
- Capacity and transport decisions get made before a site outgrows them, rather than after users start complaining.
- Rollback paths exist and have been tested before a cutover begins, not drafted during one.
- Someone who was not present for a change can understand what was done and why.
- Diagrams and configuration records match what is actually deployed.
- Where a standard exists, it is written down. Where one does not, that gap is visible rather than tribal knowledge.
- Troubleshooting knowledge ends up somewhere searchable rather than staying in your head.
Where You'd Fit
- Network Specialist. You execute changes and work incidents inside established standards. You know which problems are yours to solve and which need to go up, and you escalate before a small issue becomes an outage.
- Network Engineer. You own a segment, a site group, or a system. You make routine design calls yourself and bring the consequential ones to review.
- Senior Network Engineer. You take the problems that arrive without a clear answer.
- Other engineers check their approach with you before they commit to it, and you are usually the one who figures out why the intermittent fault is not intermittent.
- Senior Network Architect. You set the design that others build against, and you are accountable when that design meets an operational reality it did not anticipate.
- Lead Network Architect. You own whether the environment holds together as a whole, including the parts you did not design and the decisions you inherited.
What You Bring
- Bachelor’s degree in management information systems, Computer Science, Engineering, or a related technical field (e.g. Networking and Telecommunications) with 10+ years of experience performing network engineering or 14+ years of network engineering experience without a bachelor’s degree.
- Minimum of ten (10) years of verifiable network engineering experience supporting a large, complex Federal agency. Strong knowledge of networking protocols, such as TCP/IP, BGP, OSPF, EIGRP, MPLS, VPNs and VLANs.
- Expertise and experience with Cisco technology and Firewall technologies. Ability to perform firewall changes.
- Hands-on experience with SDN technologies such as Cisco ACI or VMware NSX. Excellent problem-solving and analytical skills, with the ability to troubleshoot complex network issues.
- Delivers high-level technical leadership to meet or exceed establishes project goals.
- Active Industry certifications, such as CCNA, CCNP (routing and switching)
- Nice to have: experience and expertise with Zero Trust (Zscaler) and Palo Alto technologies
- Previous experience CBP highly desired, followed by DHS or DoW
- Advance skills in 3 or more of the following:
- Cisco SD-WAN
- Cisco Hyperflex
- Cisco StealthWatch
- Cisco Application Centric Infrastructure
- Cisco Firepower
- Willing to be cross trained in the above technologies,
- You have kept a distributed network running where downtime had consequences beyond user frustration.
- You have modernized live infrastructure under change control, not only built new environments.
- You have worked at remote or austere sites and can describe what you did differently because of it.
- You have operated in mixed-vendor environments and are not dependent on one vendor's tooling.
- You hold an active CBP BI, a fitness determination at another DHS component, or an active DoD clearance. Any of these shortens your start date.
- You can work inside federal change management and accreditation without treating it as an obstacle.
- Certifications such as CCNP, CCIE, or JNCIP are useful but not a substitute for having done the work.
