Firewall Engineer Duties and Responsibilities
Firewall engineers are responsible for handling several daily tasks. We analyzed multiple job listings for firewall engineers and found that the following duties and responsibilities are commonly listed for this occupation:
Design Security Systems Firewall engineers review client requirements for security systems and collaborate with other engineers and developers to decide on an overall technical approach. Once they reach agreement with the client, they proceed with creating specific designs.
Install and Maintain Firewalls It's up to firewall engineers to direct the installation of both the software and hardware components of firewalls along with other portions of security infrastructure. They also configure firewalls for usage, manage their day-to-day operations, and perform regular maintenance through upgrades and patches.
Troubleshoot Issues Firewall engineers constantly monitor security devices and applications for performance problems and provide troubleshooting support for clients. When issues arise, they must analyze the root cause and resolve them promptly or else escalate them to another department while updating clients all throughout.
Write Documentation Aside from preparing status reports for clients, firewall engineers write extensive documentation on procedures, device statuses, firewall block lists, and other important technical areas. They also create diagrams of network topologies and record details of troubleshooting processes.
Ensure Compliance Standards and policies are extremely important when it comes to network security, and firewall engineers should be aware of these, keeping abreast of changes and defining processes for compliance. In addition, they enforce quality control and ensure that all output meets project requirements.
Firewall Engineer Skills and QualificationsFirewall engineers are problem-solvers with a strong technical aptitude. They communicate well with clients and other members of their team, and they hold their work to high standards, optimizing performance and resolving all errors. In addition to a bachelor's degree in computer engineering, computer science, or a related field, employers look for firewall engineers with the following skills:
- Expertise in computer security - firewall engineers must have advanced knowledge of computer security and networking. They're familiar with the underlying theories and can diagnose issues, build infrastructure, and work with related software
- Problem-solving skills - this role requires much problem-solving, since firewall engineers must be able to apply their technical expertise across various client environments and solve any obstacles that arise
- Customer service - firewall engineers interact with clients during all phases of the project, from planning to maintenance. In particular, they must be mindful of client needs and clearly communicate complex information
- Attention to detail - as with most other jobs that involve working with technology, firewall engineers must be meticulous and detail oriented, examining every aspect of the system to guarantee security and spot computer bugs or anomalous activity while they're still minor
- Time management - it's common for firewall engineers to multitask, as they often take on several projects at the same time while debugging problems reported by customers and coordinating with other team members
Firewall Engineer Education and TrainingMost firewall engineers have a bachelor's degree in computer engineering, information technology, computer science, or a related field. Because this position relies heavily on hard skills, significant technical training is necessary, and employers typically look for security and networking certifications from organizations such as Cisco and AXELOS. It's also preferable for candidates to have at least four years of previous experience in computer networking, especially with firewall technologies.
Firewall Engineer Salary and OutlookPayScale reports that firewall engineers have a median annual salary of around $84,000. Those in the bottom 10 percent of the income range earn less than $54,000 per year, while those in the highest 10 percent earn significantly more, with salaries going beyond $140,000. The Bureau of Labor Statistics (BLS) projects a job outlook of 6 percent growth for network and computer systems administrators, a sector that includes firewall engineers. The increasing use of information technology is a major driver, but cloud computing may bolster productivity and cut down work for network administrators.
