Job description
As you develop at Evolving Networks, there's scope to focus and specialise across:
- Networking - LAN, WAN, SD-WAN, NaaS, Layer 2, network fabrics
- Security - ZTNA, SASE, SSE, NGFW, WSG
- Infrastructure - public/private cloud, IaaS, server virtualisation, out-of-band management
We'll support your growth with structured learning & exposure to advanced projects as you continue your journey with Evolving Networks., As part of the technical team, you'll be supporting various technology functions within the business. From supporting the service desk and 1st line engineers with more complex customer issues, to taking a lead on network appliance configurations, this is a varied role covering:
- Configuring new wide area networks and resilient internet connections;
- Troubleshooting existing networks to improve bandwidth and traffic flow;
- Preparing network documentation and diagrams to agreed specifications;
- Completing firewall changes such as port forwards, VLANs and rules.
This is a mostly remote role, with quarterly visits to the office, but you'll still have hands on configuration tasks with routers, switches and our advanced network virtualisation appliances, along with supporting the service desk engineers.
Candidates able to articulate complex networking jargon into easy-to-understand terms will have an advantage.
Requirements
Do you have experience in XML?, We're looking for a capable and curious engineer with solid networking experience and at least a working knowledge (or strong interest) in Linux. You'll already be comfortable in a command-line environment and have real-world experience troubleshooting and configuring live networks.
Our ideal candidate is someone who already understands the foundations and is ready to build on them - someone who wants to go beyond the limits of traditional networking and develop expertise across Linux, open-source, automation, and next-gen network security., You might have come up through the service desk, moved into networking, and are now ready for something more advanced and hands-on. Or maybe you're an experienced network engineer in a larger organisation and want to escape the legacy systems and red tape to do something more interesting, varied, and modern.
If you've worked with traditional networking vendors, great - you'll bring valuable context. But you'll also need to be open to new ways of thinking: automation, open-source tooling, and Linux-based network infrastructure.
If you're hungry to learn, enjoy solving complex problems, and want the freedom to explore and develop specialisms across networking, security, and cloud infrastructure, you'll fit right in here.
Must haves
- Strong understanding of OSI Layer 2 (Ethernet) and Layer 3 (IP)
- Experience with network segregation (VLANs, VRFs)
- Understanding of static routing within a WAN
- Comfortable working in a CLI (local serial console, remote SSH, etc.)
- Familiarity with network diagnostic tools (tcpdump, traceroute, mtr, etc.)
That's your solid base. From there, we'll build on it together.
Toolkit
As part of your day-to-day responsibilities, you'll work with any combination of the tools and formats listed below. You'll receive training on all of them, but prior experience is an advantage:
- Reading and writing documentation using Markdown
- Reading and writing configuration files in JSON, YAML or INI formats
- Experience with other serialisation formats (such as TOML or XML) is also useful
- Running, and potentially creating, Ansible playbooks and roles, * Knowledge of dynamic routing protocols (BGP especially)
- Switching and related tech (STP, LAG, etc.)
- Understanding MTU/MSS and packet flow
- Confident with CIDR subnetting
- Familiar with tunnelling and VPNs beyond just IPSec
Security
- Understanding firewalls and access control concepts
- Experience managing ACLs, NAT rules, and VLAN segmentation
- Conceptual grasp of Zero Trust Networking and ZTNA principles
Linux
- Confident installing, using, and troubleshooting Debian-based systems
- Proficient in SSH and keypair authentication
- Familiar with basic system administration tasks
Other useful skills
- Understanding of redundancy, resilience, and high availability
- Documentation using Markdown
- Experience with Git for version control
- Basic scripting (Bash, Python)
- Automation experience (Ansible preferred)
- Familiarity with SSL, SSH, and general cryptographic fundamentals
We're not expecting anyone to have anything close to all of these skills and experience. In fact, if you still only have the "must haves" that's fine!
But the chances are, if you do, you might be able to tick a few more of these boxes, and you might already be pushing yourself to learn and understand some of them.
As you can by now appreciate, we are not looking for a square peg to fit a square hole, and we are happy to discuss a position with a broad range of candidates.
