Job description
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.
