Full Job Description

Whether you come from a background in network security, firewall engineering, or infrastructure engineering, you can be successful in this role. While a specific degree isn’t required, this role is best suited for individuals with hands-on experience in network security, access control, and policy enforcement. We’re looking for candidates who bring strong foundational expertise and are ready to continue growing their skills here.

About The Role:
As a Network Security Engineer, you’ll play a key role in securing and managing how traffic and access flow across our network environments. You’ll work across both on-premises and cloud systems, focusing on policy enforcement, secure connectivity, and access control using platforms like firewalls, ClearPass, Umbrella, and Alkira.

This is a hands-on engineering role where you’ll partner closely with network, systems, and security co-workers to ensure access to applications and infrastructure is controlled, reliable, and aligned with company standards. You’ll balance day-to-day operational support with continuous improvements to our overall network security posture.

Here’s a snapshot of what you’d be doing:

Design, implement, and maintain firewall policies, including rule lifecycle management, NAT, and segmentation strategies.
Administer and support VPN technologies, including site-to-site and remote access, while troubleshooting connectivity and access issues.
Manage network access control through ClearPass, including authentication workflows, role-based access, and device onboarding.
Configure and support DNS-layer security using Umbrella, including policy tuning and traffic control.
Support cloud networking and segmentation using Alkira, ensuring consistent policy enforcement across environments.
Integrate and support Aruba-based environments where they intersect with authentication and policy enforcement.
Perform platform maintenance, including firmware upgrades, patching, and high availability validation.
Troubleshoot access and connectivity issues across authentication, firewall policy, VPN, and DNS layers.
Analyze logs using tools like Splunk and platform-native solutions to investigate issues and validate policy behavior.
Participate in structured change management processes, ensuring changes are reviewed, documented, and auditable.
Develop and maintain documentation for configurations, standards, and operational procedures.
Collaborate with architects and engineers to improve segmentation, access models, and secure design patterns.
Leverage automation tools such as Python and REST APIs to improve efficiency in policy and object management.
Contribute to a strong team culture by pitching in where needed and supporting co-workers across Technology.

About You:

You have strong attention to detail and take ownership of maintaining accurate, well-controlled environments.
You can manage multiple priorities and adapt as operational needs shift.
You’re comfortable working in structured environments with defined processes, especially around change management and documentation.
You collaborate effectively across teams and communicate clearly when troubleshooting or implementing changes.
You approach problem-solving methodically and can work through complex access and connectivity issues.
You’re self-directed but know when to engage others to move work forward.
You show up consistently and can be counted on to get the job done.
You’re available to work outside normal business hours and/or on weekends when needed.

Required Experience:

3+ years of experience in network security, firewall administration, or a closely related role.
Hands-on experience managing firewall policies, NAT, and VPN technologies.
Experience with network access control systems such as ClearPass or similar NAC platforms.
Strong troubleshooting skills across multiple layers, including authentication, policy enforcement, and network connectivity.
Experience working within formal change management processes.
Familiarity with log analysis tools such as Splunk.

About Us:

We’re all about helping Veterans and military families become homeowners. In two short decades, we closed over 500,000 VA Loans and became the #1 VA lender for homebuyers in the nation. But to us, success isn’t measured in numbers. Our success is measured in living our values every day: Be Passionate and Have Fun, Deliver Results with Integrity and Enhance Lives Every Day. We always strive to provide friendly service to military homebuyers and their families. And we always seek to lift up people and communities across the country.

We’re so glad you’re here checking out this opportunity! If this role gets you excited but you’re worried you don’t check every box – don't sweat it. We’re more interested in what you can bring to the team than a perfect checklist. If you’re passionate, driven, and ready to make a difference, we’d love to hear from you. Come as you are, and together we’ll create something amazing.
