Exos is seeking a Network Security Engineer (focused on Firewalls & F5 technologies) to support a large, regulated environment. This engineer will have a heavy focus on Palo Alto Networks solutions and supporting a high volume of security and network initiatives.

The ideal candidate is a hands-on engineer who can own delivery work, troubleshoot complex issues when something is not behaving as expected, and communicate clearly with both technical and non-technical stakeholders. Cybersecurity knowledge and experience in converting security policies into practical technical solutions is a strong plus.

Description:
  • Designing, implementing, and supporting enterprise firewall solutions, with a primary focus on Palo Alto Networks firewalls.
  • Configuring, managing, and troubleshooting F5 technologies (e.g., LTM, GTM/DNS, ASM or similar modules) in a complex environment.
  • Building, maintaining, and optimizing firewall and application delivery policies, rule sets, and related configurations to support business and security requirements.
  • Serving as a hands-on engineer for multiple concurrent projects, ensuring high-quality, on-time implementation.
  • Troubleshooting and resolving complex network and security issues across firewalls, F5 platforms, and related infrastructure.
  • Working closely with security architects and other stakeholders to translate security and compliance policies into technical controls and solutions.
  • Documenting designs, changes, runbooks, and standard operating procedures for ongoing operations and support.
  • Collaborating with cross-functional teams (network, security, application, and operations) and communicating clearly with stakeholders who may not have deep cybersecurity experience.
  • Supporting additional firewall platforms as needed (e.g., SAP-related firewalls or other vendor solutions).


Requirements:
  • 5+ years of hands-on experience as a Network Security Engineer, Firewall Engineer, or similar role.
  • Strong, practical experience with enterprise firewalls, ideally including Palo Alto Networks (policy creation, rule tuning, troubleshooting, and upgrades).
  • Solid experience with F5 technologies in production environments (load balancing, traffic management, and/or application security).
  • Proven experience supporting or delivering solutions in regulated environments (e.g., financial services, healthcare, utilities, or other highly governed industries).
  • Demonstrated ability to independently deliver technical work while also escalating and collaborating effectively when needed.
  • Strong troubleshooting skills across network and security layers, including root-cause analysis and remediation.
  • Excellent communication skills, with the ability to work with stakeholders who may not be deeply technical.
