Testing and investigation * Build and maintain test plans, environments, and device configurations that mirror real installations * Configure and test on platforms such as Control4, RTI, and Crestron * Test drivers, integrations, features, and bug fixes before release * Reproduce customer-reported issues, analyse logs and device communications, and get to root cause * Give developers clear diagnostic information, then retest and confirm the fix * Keep our library of test hardware, drivers, and configurations organised Customer and installer support * Manage support tickets and help installers and integrators resolve technical issues * Guide users through setup, configuration, and troubleshooting - including remote access to customer systems where needed * Spot recurring problems and turn them into product or process improvements Documentation and video * Write installer guides, user guides, quick-start guides, and knowledge-base content * Produce step-by-step setup and troubleshooting instructions, FAQs, screenshots, and diagrams * Plan, record, and edit short setup and troubleshooting videos with screen capture, callouts, and voiceovers * Keep everything accurate as the products evolve Video is a small part of the role today, with plenty of room to grow it if that's an area you want to own., * Control4, RTI, Crestron, URC, ELAN, or similar control platforms * Wireshark, Postman, SSH, Telnet, or serial-console tools * TCP/IP, DHCP, DNS, routing, and switching * Git, GitLab, Jira, Azure DevOps, or Monday.com * Testing IoT, AV, or embedded hardware products * OBS Studio, Camtasia, DaVinci Resolve, or similar * AV-over-IP and smart-home technologies * AI tools such as Microsoft Copilot or Claude Don't worry if you don't tick every box - if you've got the core testing and communication skills, we'll help you learn the rest. What success looks like You find issues before customers do. Developers get what they need to fix things quickly. Installers get answers fast. And the guides you write mean they need to ask less often.
