The important thing is that you understand networking properly. We're looking for solid TCP/IP and L2/L3 knowledge alongside hands-on experience with areas such as enterprise firewalls, LAN/WAN, routing and switching, VPNs, SD-WAN and network security. Ideally, you'll have experience implementing or upgrading network/security solutions rather than purely supporting an existing environment. Experience working within an MSP, ISP, network integrator or consultancy would translate particularly well because you'll be working across multiple customer environments. You'll also need to be comfortable speaking with customers, troubleshooting independently and taking ownership of problems through to resolution. ## Description If you're a Network Engineer who has naturally moved more into the security side of things, or you're already working within network security and want more exposure to design, consultancy and project work, this could be a really good next step. We're working with a growing specialist network and connectivity business that designs, builds and supports complex network environments for large organisations across the UK. Due to continued growth, they're looking to add another Network Security Consultant to the team. This isn't a role where you'll spend all week sat in a ticket queue. There is a support element, but you'll also get involved in designing solutions, delivering projects, implementing new technology and working directly with customers. One of the big selling points here is the development. They're happy to invest in people and will fund relevant professional qualifications and certifications, giving you the opportunity to keep developing technically and progress further into network security, consultancy and architecture. Day to day You'll be working across a mixture of network and security projects, implementations and 3rd line escalations. That could mean designing and deploying firewalls, working on VPN or SD-WAN solutions, troubleshooting a complex network issue, completing an upgrade or helping deliver a wider customer infrastructure project. You'll work across LAN/WAN environments alongside technologies covering enterprise firewalls, routing and switching, VPNs, web filtering, identity and access management and wider network security. There is a customer-facing element too. You'll be involved in gathering requirements, producing technical designs and implementation plans, carrying out network/security health checks and talking customers through the solutions you're delivering. The environments are business-critical, so there is an out-of-hours/on-call element to the position, which we can talk you through properly before you decide whether the opportunity is right for you. ## 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) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [Lies, Damned Lies and Large Language Models](https://www.wearedevelopers.com/videos/1231-lies-damned-lies-and-large-language-models) - [Cyber Sleuth: Finding Hidden Connections in Cyber Data](https://www.wearedevelopers.com/videos/893-cyber-sleuth-finding-hidden-connections-in-cyber-data) - [A Technical Introduction to Bitcoin's 2nd Layer- The Lightning Network](https://www.wearedevelopers.com/videos/15-a-technical-introduction-to-bitcoin-s-2nd-layer-the-lightning-network) ## Related Articles - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [IT Salaries in UK](https://www.wearedevelopers.com/magazine/288-it-salaries-in-uk) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market)
