Coordinate with vendors or service providers (ISP, cloud services) when external support or escalation is needed.

Documentation and Network Administration: Maintain up-to-date documentation of network configurations, IP address assignments, diagrams, and change logs. Follow change management processes when making network changes (e.g. recording configuration changes, firmware updates). Create and update network topology diagrams, standard operating procedures,

and user guides (for example, VPN setup instructions) as needed to ensure knowledge is shared and audits can be passed.

Disaster Recovery and Maintenance: Perform regular data and configuration backups for critical network devices and implement disaster recovery procedures. Schedule routine maintenance and upgrades (e.g. applying patches, renewing certificates, replacing faulty hardware) during appropriate maintenance windows to minimize disruption. Test failover mechanisms and backup links (if available) to ensure high-availability network design for critical systems.

Stay Current and Continuous Improvement: Keep abreast of new networking technologies, cloud integration methods, and best practices relevant to SMB environments. Attend training or workshops to continuously improve skills. Proactively recommend and implement network improvements or optimizations (such as refining Wi-Fi coverage, segmenting traffic with VLANs, or adopting better monitoring tools) to enhance performance, security, and scalability of the network.

Networking Fundamentals: Strong understanding of TCP/IP networking, subnetting, routing and switching concepts, VLANs, and common protocols like DNS and DHCP. Should be able to configure and troubleshoot IP addressing issues, DHCP assignments, name resolution problems, and basic routing for an SMB network.

Network Hardware & Architecture: Hands-on experience configuring routers, switches, and wireless APs, ideally from mainstream vendors (e.g., Cisco, HP/Aruba, Ubiquiti). Familiarity with firewall appliances or UTM devices for SMB (such as Cisco ASA/Meraki, Fortinet, or SonicWall) and understanding of how to set up site-to-site and client VPNs. Able to interpret network diagrams and deploy network gear in a structured way.

Network Security Practices: Solid knowledge of network security principles and tools for example, able to configure firewall rules, VPN access, VLAN segmentation, and wireless security (WPA2/3). Understands how to apply updates/patches, manage user access control, and implement secure protocols to protect data in transit. Basic awareness of intrusion detection/ prevention and common threats (phishing, malware traffic) to quickly respond to security incidents.

Troubleshooting & Tools: Proficiency with network troubleshooting tools and methodologies. Can use utilities like ping, traceroute, and nslookup to diagnose issues, and analyze packet captures with Wireshark or similar tools. Experience with network monitoring software (e.g., SolarWinds, PRTG, Nagios) to track performance and outages. Able to systematically isolate problems (layer-bylayer troubleshooting of OSI model) and resolve them under time pressure.

Cloud & Hybrid Networking: Familiarity with integrating on-premise networks with cloud services. For example, knowledge of Azure or AWS networking basics (virtual networks, VPN gateways) to support an Office 365 or cloud-hybrid environment. Understands how services like Microsoft 365 or Google Workspace tie into network considerations (such as ensuring DNS, firewall, and identity (Azure AD/Google) configurations allow smooth access for users)

Automation/Scripting (Nice-to-have): Ability to automate routine tasks or configurations using scripts or tools (PowerShell, Python, or Ansible). While not a primary duty in SMB, scripting skills are a plus for efficiency e.g., automating network device backups or bulk updates. This reflects a modern mindset to reduce manual repetitive work (as network automation skills are increasingly in demand)

Analytical Problem-Solving: Strong troubleshooting and analytical thinking skills to diagnose complex networking issues. Able to break down problems, find root causes, and devise effective solutions calmly. This includes a dose of creativity and persistence when facing unfamiliar issues, ensuring minimal downtime.

Communication Skills: Excellent ability to communicate technical information to non-technical staff in clear, simple terms. Can listen to user concerns, ask probing questions, and explain solutions or preventive measures without jargon. Also capable of writing clear documentation and status reports (e.g., incident reports, user advisories). Effective communication is considered a secret weapon for network engineers to influence and collaborate

Teamwork and Interpersonal Skills: Works well in cross-functional teams and can collaborate with colleagues in IT support, software, or operations. Strong teamwork skills willing to assist others, share knowledge, and coordinate tasks to achieve bigger IT goals. Builds positive relationships with coworkers and vendors, and demonstrates empathy and patience when dealing with end-users frustrations.

Time Management: Able to juggle multiple tasks and prioritize effectively, especially when dealing with concurrent issues or projects. For example, can balance an urgent outage with routine maintenance duties by triaging impact. Meets project deadlines for network upgrades or deployments through careful planning and scheduling, which is vital in a resource-constrained SMB environment.

Attitude and Work Ethic:

Detail-Oriented and Thorough: Diligence in attention to detail is essential small misconfigurations can cause big problems. A good network admin double-checks IP addresses, cable placements, and configuration changes. This reduces errors and avoids rework or downtime Being detail-oriented ensures IT infrastructure is set up correctly the first time, without needing frequent troubleshooting for avoidable mistakes

Reliability and Responsibility: A dependable professional who takes ownership of the networks uptime and security. Reliability and responsibility are top traits valued by hiring managers for engineering roles.
