A link failure, a misapplied firewall rule, or unstable Wi-Fi can block payments, patient files, or field teams.<\/p>\n<p>His role consists of designing, deploying, administering, and evolving communication networks: local area network (LAN), wide area network (WAN), Wi-Fi, firewalls, routing, site interconnections, and monitoring. Job titles also include Network &amp; Security Engineer, Systems and Networks Engineer, or Network Consultant. In Libreville, Abidjan, Dakar, or Douala, versatility in networking, security, and telecommunications is often decisive.<\/p>\n<\/div>\n<aside class=\"metier-brief\">\n<p class=\"metier-brief__label\">The profession in 30 seconds<\/p>\n<p>The network engineer ensures that users, applications, servers, remote sites, and cloud services communicate correctly, with an appropriate level of availability and security.<\/p>\n<p>He works on routers, switches, firewalls, Wi-Fi access points, operator links, virtual private networks (VPN), and monitoring tools.<\/p>\n<p>The position often requires a Bac+5 level, but some profiles evolve from network administration, infrastructure support, or telecommunications with experience and certifications.<\/p>\n<p>In French-speaking Africa, job offers frequently combine networking and security: segmentation, firewalling, MPLS, BGP, fiber, incidents, and relationships with operators.<\/p>\n<\/aside>\n<h2>What is the purpose of this professional?<\/h2>\n<p>The network engineer makes the digital infrastructure reliable, efficient, and secure. Without them, business applications, messaging, VoIP calls, Internet access, payment terminals, cloud tools, or connections between agencies can become unstable or unavailable.<\/p>\n<p>They do not just \"plug in cables.\" They analyze needs, propose an architecture, choose equipment, configure protocols, document choices, supervise performance, and intervene on complex incidents. In multi-site organizations, they are also the point of contact for operators, integrators, cybersecurity teams, and business management.<\/p>\n<h2>A typical day<\/h2>\n<p class=\"metier-day__note\">Example of a typical day, not an observed report.<\/p>\n<ol class=\"metier-day\">\n<li><span class=\"metier-day__time\">8:30 AM<\/span> monitoring alerts, checking WAN links, and analyzing incidents opened overnight.<\/li>\n<li><span class=\"metier-day__time\">9:30 AM<\/span> meeting with the security team to validate a new network segmentation and firewall rules.<\/li>\n<li><span class=\"metier-day__time\">11:00 AM<\/span> configuring a router, backing up the configuration, and updating the network diagram in the documentation.<\/li>\n<li><span class=\"metier-day__time\">2:00 PM<\/span> discussing with a telecom operator about a decrease in service quality between two agencies.<\/li>\n<li><span class=\"metier-day__time\">4:00 PM<\/span> testing a VPN access for remote users, checking logs, and correcting an access rule.<\/li>\n<li><span class=\"metier-day__time\">5:30 PM<\/span> preparing a maintenance window: rollback plan, informing the business units, and validation with the IT manager.<\/li>\n<\/ol>\n<h2>What skills?<\/h2>\n<div class=\"metier-skills\">\n<div class=\"metier-skills__col\">\n<p class=\"metier-skills__label\">Techniques<\/p>\n<ul>\n<li>TCP\/IP, IPv4\/IPv6, VLAN, DNS, DHCP, and SNMP.<\/li>\n<li>OSPF routing, BGP, sometimes ISIS, MPLS, and Metro Ethernet.<\/li>\n<li>Configuration of routers, switches, firewalls, and Wi-Fi access points.<\/li>\n<li>IPsec VPN, segmentation, IDS\/IPS, and filtering rules.<\/li>\n<li>Monitoring with Zabbix, Centreon, PRTG, Grafana, or equivalent tools.<\/li>\n<li>Linux basics, Windows Server, virtualization, cloud, and automation with Python or Ansible.<\/li>\n<\/ul>\n<\/div>\n<div class=\"metier-skills__col\">\n<p class=\"metier-skills__label\">Organizational<\/p>\n<ul>\n<li>Methodical diagnosis in incident situations.<\/li>\n<li>Writing procedures, diagrams, and architecture documents.<\/li>\n<li>Change management and maintenance windows.<\/li>\n<li>Monitoring of service providers, operators, and suppliers.<\/li>\n<li>Monitoring trends in SD-WAN, SASE, enterprise Wi-Fi, IPv6, and cybersecurity.<\/li>\n<\/ul>\n<\/div>\n<div class=\"metier-skills__col\">\n<p class=\"metier-skills__label\">Human<\/p>\n<ul>\n<li>Service orientation towards users and business teams.<\/li>\n<li>Responsiveness without haste during a critical failure.<\/li>\n<li>Clear communication with the information systems management.<\/li>\n<li>Teamwork with support, cybersecurity, cloud, and telecommunications.<\/li>\n<li>Technical English for documentation, vendor tickets, and certifications.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h2>What studies?<\/h2>\n<p>The most common path remains a Bac+5 education: engineering school, master's in computer science, networks and telecommunications, information systems, or cybersecurity. Apec indicates this reference level for network engineers, with access possible for recent Bac+5 graduates, although prior experience in network or telecom administration is often appreciated.<\/p>\n<p>A Bac+3 can provide entry through network administration, infrastructure support, operations, or telecommunications, before evolving into an engineering position. Certifications significantly strengthen the profile: Cisco Certified Network Associate (CCNA), Cisco Certified Network Professional (CCNP), Fortinet, Palo Alto, Huawei Datacom, Juniper, Stormshield, ITIL Foundation, or cloud network certifications depending on the targeted environments. No training guarantees recruitment: internships, lab projects, produced documentation, and field experiences are highly valued.<\/p>\n<h2>Where does he work?<\/h2>\n<p>Employers are varied: banks, insurance companies, fintech, telecom operators, Internet service providers, administrations, public agencies, large multi-site companies, digital services companies (ESN), network integrators, data centers, cloud providers, international NGOs, universities, hospitals, transport, and energy.<\/p>\n<ul class=\"metier-titles\">\n<li>Network Engineer F\/M<\/li>\n<li>Network Engineer<\/li>\n<li>Network and Security Engineer<\/li>\n<li>Networks &amp; Security Engineer<\/li>\n<li>Systems and Network Engineer<\/li>\n<li>Networks and Telecommunications Engineer<\/li>\n<li>Network Consultant<\/li>\n<li>System\/Network Consultant<\/li>\n<li>Network Administrator<\/li>\n<li>Technical Sales Engineer for Networks and IT Infrastructure<\/li>\n<\/ul>\n<h2>What is the salary?<\/h2>\n<p>In France, Apec indicates that for network engineer positions, the gross annual fixed plus variable salary is between \u20ac37,000 and \u20ac55,000 for 80% of the offers, with an average of \u20ac45,000. An offer in Toulouse for an experienced profile in critical networks was listed at \u20ac48,000 to \u20ac55,000 per year. These ranges do not automatically translate to Gabon, Senegal, Cameroon, or C\u00f4te d'Ivoire.<\/p>\n<p>For Francophone Africa, reliable public data precisely aligned with the title is rarer. In C\u00f4te d'Ivoire, salaire.africa, based on the Grey Search Africa 2024-2025 guide, provides for Abidjan a Systems\/Networks Engineer position: junior under 5 years, 250,000 to 920,000 FCFA per month, average 485,000 FCFA; confirmed 5 to 10 years, 310,000 to 1,168,000 FCFA, average 639,000 FCFA; senior over 10 years, 394,000 to 1,390,000 FCFA, average 792,000 FCFA. For Senegal, Gabon, and Cameroon, the consulted sources do not allow for publishing a reliably comparable range.<\/p>\n<h2>The realities to know<\/h2>\n<ul>\n<li>On-call duties are possible when the infrastructure is critical.<\/li>\n<li>A network outage can halt an entire activity: the pressure is high.<\/li>\n<li>Security involves technical responsibility: VPN, firewall, and segmentation must be mastered.<\/li>\n<li>Documentation of existing networks is sometimes incomplete or outdated.<\/li>\n<li>Deadlines often depend on operators, integrators, licenses, and support contracts.<\/li>\n<li>The testing laboratory, replacement equipment, and budgets are not always available.<\/li>\n<\/ul>\n<h2>And in Africa?<\/h2>\n<p>In Abidjan and Dakar, the offers reviewed show a hybrid need: enterprise network, telecoms, and security. The required skills cover LAN, WAN, and WLAN networks, firewalls, VPN, IDS\/IPS, MPLS, BGP, IPv4\/IPv6, FTTH\/GPON, monitoring, and incident management. In a bank, an administration, or an operator, the network is not a secondary issue: it conditions payments, agencies, online services, and business continuity.<\/p>\n<p>In Libreville, Douala, or in secondary cities, the context can be more hands-on than a European job description: cabling, energy, air conditioning, quality of operator links, old equipment, access to licenses, and import delays. The same professional may need to discuss architecture in the morning, user support in the afternoon, and security audit at the end of the week.<\/p>\n<p>Remote work exists for monitoring, documentation, auditing, level 2 or 3 support, and managing service providers. However, equipment replacements, fiber measurements, patching, Wi-Fi installations, and data center interventions still require physical presence.<\/p>\n<h2>Is this job for you?<\/h2>\n<ul>\n<li>Do you like to understand why a connection works or does not work?<\/li>\n<li>Are you able to remain methodical when multiple services are down?<\/li>\n<li>Do you agree to document your configurations and changes precisely?<\/li>\n<li>Do you want to continuously learn about protocols, equipment, and security practices?<\/li>\n<li>Can you explain a technical problem to a user, a manager, or a service provider?<\/li>\n<\/ul>\n<p>If you enjoy concrete infrastructures, precise diagnostics, and visible responsibilities, this job may suit you. However, it requires rigor, availability, and a genuine ability to learn outside of classes.<\/p>\n<h2>Related professions<\/h2>\n<ul>\n<li><a href=\"https:\/\/univga.org\/en\/expert-profession-in-remote-work-and-collaborative-work\/\">Digital Workplace Consultant: profession, missions, and opportunities<\/a><\/li>\n<li><a href=\"https:\/\/univga.org\/en\/cloud-computing-analyst-profession\/\">Cloud Computing Analyst Profession<\/a><\/li>\n<li><a href=\"https:\/\/univga.org\/en\/cyber-risk-analyst-profession\/\">Cyber Risk Analyst Profession<\/a><\/li>\n<li><a href=\"https:\/\/univga.org\/en\/software-developer-profession\/\">Software Developer: profession, missions, and opportunities<\/a><\/li>\n<li><a href=\"https:\/\/univga.org\/en\/database-administrator-profession\/\">Database Administrator Profession<\/a><\/li>\n<\/ul>\n<h2>Sources<\/h2>\n<ol>\n<li><a href=\"https:\/\/www.apec.fr\/tous-nos-metiers\/informatique\/ingenieur-reseaux.html\">Apec: Network Engineer, job description<\/a><\/li>\n<li><a href=\"https:\/\/www.emploi.ci\/offre-emploi-cote-ivoire\/ingenieur-reseau-securite-abidjan-1878075\">Emploi.ci: Network and Security Engineer position, Abidjan<\/a><\/li>\n<li><a href=\"https:\/\/emploi.toulouse-metropole.fr\/candidat\/offres\/offre-d-emploi-ingenieur-reseaux-h-f-toulouse-occitanie-cdi-506033\">Emploi Toulouse M\u00e9tropole: Network Engineer position F\/H<\/a><\/li>\n<li><a href=\"https:\/\/www.emploisenegal.com\/offre-emploi-senegal\/ingenieur-reseaux-telecom-dakar-1301252\">Emploi S\u00e9n\u00e9gal: Network and Telecom Engineer position, Dakar<\/a><\/li>\n<li><a href=\"https:\/\/www.cisco.com\/site\/us\/en\/learn\/training-certifications\/certifications\/enterprise\/ccna\/index.html\">Cisco: CCNA certification<\/a><\/li>\n<li><a href=\"https:\/\/www.salaire.africa\/cotedivoire\/systemes-dinformation\/ingenieur-systemes-reseaux\">salaire.africa: Systems\/Networks Engineer in C\u00f4te d\u2019Ivoire<\/a><\/li>\n<\/ol>\n<aside class=\"veille-univga-encart\">\n<p class=\"veille-univga-encart__label\">Training at UNIVGA<\/p>\n<p>UNIVGA offers professional certificates and degree programs in digital, management, and cybersecurity.
