Remote Cybersecurity Job — But Colorado Residents Only
Although the position is advertised as remote, applicants should pay close attention to the location requirement.
The job specifically states that candidates must be local to Colorado.
This means it should not be treated as a fully location-independent work-from-home position where someone can apply from anywhere in the United States.
The role is connected to the State of Colorado and requires the contractor to work on a schedule based on Mountain Standard Time (MST).
Candidates should therefore be prepared to work remotely while remaining geographically available to the Colorado-based client.
What Does a Network Security Engineer Do?
A network security engineer or network security administrator is responsible for protecting an organisation’s computer networks, systems and digital infrastructure.
The role combines network engineering and cybersecurity.
Typical responsibilities can include:
- Managing firewalls
- Configuring security policies
- Monitoring network infrastructure
- Managing VPN connections
- Troubleshooting network security problems
- Implementing security controls
- Responding to incidents
- Maintaining compliance
- Managing network hardware
- Supporting infrastructure upgrades
- Reviewing security requests
- Testing network changes
In this particular position, the contractor will support multiple state agencies and help maintain secure and compliant government network infrastructure.
Key Responsibilities
Firewall Administration
One of the most important parts of the position is firewall administration.
The contractor will configure and manage both Cisco ASA and Palo Alto firewalls.
Responsibilities include reviewing firewall service requests, implementing configuration changes, troubleshooting problems and managing security rules.
Experience with enterprise firewall technology is therefore essential.
Cisco ASA Firewall Management
Candidates should have experience with Cisco ASA (Adaptive Security Appliance) firewalls.
The required knowledge includes:
- Configuration
- Troubleshooting
- Rule management
- Firewall administration
- Security policy implementation
- Hardware administration
Cisco ASA remains an important technology for professionals working with established enterprise network environments.
Palo Alto Firewall Administration
The role also requires knowledge of Palo Alto Networks firewalls.
Candidates should understand next-generation firewall capabilities including:
- Security zones
- Security policies
- Site-to-site VPN
- Network address translation (NAT)
- Basic threat prevention
Experience with Palo Alto Networks technology can be particularly valuable for professionals building careers in network security and enterprise cybersecurity.
Network Security and Cybersecurity
The position focuses heavily on maintaining secure government network infrastructure.
The contractor will help state agencies address operational security requirements and implement configurations designed to protect networks and systems.
This includes maintaining security controls and supporting compliance with applicable requirements.
Professionals interested in cybersecurity careers, information security, network defence and enterprise security may find the responsibilities particularly relevant.
Government Cybersecurity Compliance
Another major component of the role is regulatory compliance.
The contractor will help ensure that network configurations and security controls remain aligned with requirements associated with:
- IRS standards
- FBI requirements
- Criminal Justice Information (CJI) compliance
- Regulatory security controls
- Government security policies
This makes the role particularly relevant to IT professionals with experience in government cybersecurity, security compliance, regulatory compliance and information security.
Infrastructure Modernisation
The position is not limited to day-to-day firewall administration.
The contractor will also participate in network infrastructure modernisation.
This includes helping decommission outdated or End-of-Life (EOL) hardware and replacing it with newer infrastructure.
Hardware lifecycle management is an important part of enterprise IT because unsupported equipment can create security, reliability and compliance risks.
The contractor will therefore help ensure that network infrastructure remains modern and supportable.
Security Requests and Change Management
The role involves reviewing and executing Firewall Service Requests (FSRs), break-fix tickets and formal change requests.
This requires careful change management because modifications to network security infrastructure can affect multiple systems and users.
The contractor will need to understand:
- Change control
- Change requests
- Configuration management
- Testing
- Emergency response
- Security procedures
- Network maintenance
Strong documentation and adherence to established procedures will be important.
VPN and Network Security
Knowledge of Virtual Private Network (VPN) technology is another requirement.
Candidates should be comfortable working with VPN configurations, including site-to-site VPNs on Palo Alto firewalls.
VPN technology remains widely used by organisations to provide secure connections between networks, offices, data centres and other infrastructure.
Networking Knowledge Required
In addition to firewall expertise, applicants need a solid foundation in general networking.
The listing specifically mentions knowledge of:
Routing Protocols
Candidates should understand the fundamentals of network routing and how traffic moves between different networks.
Subnetting
Subnetting is a fundamental networking skill and is particularly important when configuring firewall rules, network zones and routing.
OSI Model
Applicants should understand the Open Systems Interconnection (OSI) model and how different networking technologies operate across its layers.
A strong networking foundation is essential for troubleshooting complex security problems.
Remote IT Job Schedule
The position follows a standard full-time schedule:
Monday to Friday
8:00 AM – 5:00 PM MST
The contractor is expected to work approximately 40 hours per week.
However, this is not strictly a Monday-to-Friday, daytime-only position.
On-Call Rotation
The contractor must participate in a weekly on-call rotation.
This means the successful candidate may need to respond to network security incidents outside normal working hours.
After-Hours Maintenance
The role may also require availability for:
- Scheduled maintenance windows
- Emergency network incidents
- Critical security issues
- Infrastructure changes
- Emergency response
Candidates should therefore be comfortable with occasional work outside the standard schedule.
Background Checks Required
Applicants must be able to pass several background checks.
The listing states that candidates may be subject to:
- Criminal background checks
- Financial background checks
- Drug testing
Because the role supports state agencies and government-related infrastructure, applicants should be prepared for a potentially more extensive screening process than they might encounter in a standard private-sector IT position.
Skills and Technologies
The position covers a broad range of network security and IT infrastructure skills.
Important technologies and concepts include:
- Cisco ASA
- Palo Alto Networks firewalls
- Firewall administration
- Network security
- VPN
- Site-to-site VPN
- NAT
- Security policies
- Network administration
- Routing protocols
- Subnetting
- OSI model
- Configuration management
- Change control
- Hardware administration
- Infrastructure modernisation
- Regulatory compliance
- Security testing
- Emergency response
