The role collaborates with network engineering, EUC, platform, and security teams to validate changes, diagnose issues, and document outcomes across on-prem and cloud-connected environments. Your responsibilities LAN Network Testing * Execute end-to-end LAN connectivity tests: VLAN segmentation, IP addressing, DHCP leasing, DNS resolution, routing behavior, and switch port configurations. * Validate QoS/traffic shaping, ACLs, and firewall rules affecting application reachability. * Test redundancy and failover (e.g., dual links, LAG, spanning tree behavior, HA pairs). * Perform latency, jitter, throughput, and packet loss validation for critical apps (monitor via ping/traceroute, iperf/ttcp-if allowed-and switch/router counters). * Conduct pre- and post-change verification for network maintenance windows and produce test evidence. * Validate file share availability, permissions, and access control (NTFS/ACLs, POSIX permissions) across user groups and service accounts. * Test EFS (Encrypted File System) behavior: * Access behaviors for encrypted vs. non-encrypted files across users and devices. * Backup/restore of encrypted data and recovery workflows. * Validate SMB/NFS share access, file locking, path lengths, special characters, and concurrency. * Test file system quotas, version history (if applicable), offline files/caching, and antivirus/EDR interactions. * Perform data integrity checks: hashing, corruption scenarios, and file copy/move behavior across networks. * Validate mounting of network shares (Windows: drive mapping/UNC paths; Linux/macOS: mount for NFS/SMB). * Test wireless access point connectivity and roaming: SSID availability, authentication (WPA2/WPA3/802.1X), captive portal, and RADIUS/certificate flows. * Evaluate performance across 2.4 GHz vs 5 GHz bands, channel utilization, and AP load scenarios. * Verify ZTP/AP provisioning behavior (if in scope) and controller-based policy application. * Test device profile differences (laptop, VDI/thin client, rugged devices) and guest vs corporate SSIDs. * Create test plans, test cases, and test data aligned with change requests and release plans. * Execute functional, regression, smoke, and integration tests; log defects with full reproduction steps and evidence. * Participate in Go/No-Go and UAT cycles; provide structured status reporting (daily/weekly). * Ensure compliance with change management/ITIL processes and maintain audit-ready documentation. Key Skills & Qualifications Technical Skills * 3-7 years in manual testing with strong network and file system testing exposure. * Solid understanding of TCP/IP, DHCP, DNS, NAT, routing, VLANs, ACLs, and 802.1X. * Hands-on experience with SMB/NFS, NTFS/ACLs, EFS, and share permissions (Windows & Linux). * Familiarity with wireless AP testing (SSID, encryption standards, roaming) and network tools (e.g., ping, traceroute, Wireshark/tcpdump, netstat). * Proficiency with test management and defect tracking (Azure DevOps, JIRA, ALM). * Ability to analyze system, network, and security logs (Event Viewer, syslog, controller logs). Soft Skills * Strong analytical and troubleshooting mindset with meticulous documentation. * Clear communication with cross-functional teams (network, EUC, security, platform). * Ability to operate under change windows and navigate production-grade testing safely. SC Clearance Eligibility Candidates must be eligible for UK SC clearance, which generally requires: * Minimum 5 years of continuous UK residency * Clean criminal and financial/credit records * Ability to meet all UK government vetting requirements Active SC clearance is preferred but not essential. ## Related Videos - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Using WebAssembly to run, extend, and secure your application](https://www.wearedevelopers.com/videos/652-using-webassembly-to-run-extend-and-secure-your-application) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [On developing smartphones on wheels](https://www.wearedevelopers.com/videos/258-on-developing-smartphones-on-wheels) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [IT Salaries in UK](https://www.wearedevelopers.com/magazine/288-it-salaries-in-uk) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [UK Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/326-uk-business-culture-and-etiquette) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
