You must, however, demonstrate the ability and motivation to learn the portions of the technology stack you do not already know. ## Description We are looking for someone who understands networking fundamentals and wants to develop into a highly capable network systems specialist. This is not a basic help-desk or access-point installation position. The right person will install and support the complete UniFi ecosystem, learn UISP and wireless ISP infrastructure, configure MikroTik routers and grow into diagnosing and resolving Layer 2 and Layer 3 network problems. You do not need to know every system we use on your first day. You do need the technical foundation, curiosity and discipline to learn them. What You'll DoUniFi systems * Install and configure UniFi gateways, switches, wireless access points and cameras * Configure VLANs, networks, DHCP, DNS, NAT, firewall rules, port profiles and PoE * Support UniFi Network, Protect, Access, Talk, Identity and Site Manager * Configure UniFi Talk phones, users, voicemail, call routing and number assignments * Help diagnose VoIP issues involving SIP registration, NAT, QoS, voice VLANs, call routing and one-way audio * Monitor customer sites, manage firmware and backups, and troubleshoot remotely or on-site * Document installations, configurations and network changes UISP and wireless infrastructure * Adopt, configure and monitor devices through UISP * Work with Ubiquiti airMAX, LTU, airFiber and Wave equipment * Assist with point-to-point and point-to-multipoint wireless systems * Provision subscriber equipment and customer connections * Diagnose signal, alignment, interference, capacity and performance issues * Determine whether problems originate at the physical, RF, Layer 2 or Layer 3 level * Perform field installations, equipment replacements and network upgrades Routing and network operations * Configure and support MikroTik RouterOS * Work with interfaces, bridges, VLANs, DHCP, NAT, firewall rules and static routes * Diagnose connectivity using ping, traceroute, ARP tables, MAC tables, logs and packet captures * Access equipment through controllers, web interfaces, SSH and console connections * Back up configurations and follow controlled change procedures * Progress into VPNs, policy routing, OSPF, BGP and ISP core-network operations * Participate in outage response and after-hours support after completing training, During your first several months, you will work with our experienced network staff to learn CIS standards, systems and network architecture. Your development will generally progress through: * UniFi installations, support and documentation * UniFi Talk and other UniFi applications * UISP monitoring and subscriber provisioning * Wireless link configuration and troubleshooting * MikroTik switching, routing and firewall configuration * Independent Layer 2 and Layer 3 troubleshooting * OSPF, BGP and ISP core-network operations The successful candidate will gradually take ownership of customer networks and smaller infrastructure sites before progressing into more consequential production-network changes. Why Join CIS? This position offers the opportunity to work across a much broader technology stack than a conventional IT support role. You will gain practical experience with customer networks, enterprise Wi-Fi, VoIP, fixed wireless infrastructure, network routing and the operation of a growing local ISP. We are looking for someone who wants to build systems, solve difficult problems and grow into a trusted network engineer-not someone who only wants to follow installation checklists. ## Related Videos - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [IP Authentication: A Tale of Performance Pitfalls and Challenges in Prod](https://www.wearedevelopers.com/videos/1413-ip-authentication-a-tale-of-performance-pitfalls-and-challenges-in-prod) - [Getting under the skin: The Social Engineering techniques](https://www.wearedevelopers.com/videos/38-getting-under-the-skin-the-social-engineering-techniques) - [Demystifying application networking in the cloud](https://www.wearedevelopers.com/videos/675-demystifying-application-networking-in-the-cloud) - [Small, Secure, Interconnected: The next Internet Protocol](https://www.wearedevelopers.com/videos/100062-small-secure-interconnected-the-next-internet-protocol) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [How to Write a CV and Interview if You Don't Fully Qualify For The Job](https://www.wearedevelopers.com/magazine/183-how-to-write-a-cv-and-interview-if-you-don-t-fully-qualify-for-the-job) - [7 Important Tips That Every Software Developer Should Know](https://www.wearedevelopers.com/magazine/101-7-important-tips-that-every-software-developer-should-know)
