Duration: 6 months+ (inside IR35)
Our client, a leading telecommunications organisation, is seeking an experienced Technical Investigation Engineer/Broadband CPE Test Engineer to join their Home Hub In-Life team. This is an exciting opportunity for a technically driven engineer with a background in broadband devices, Wi-Fi technologies, embedded systems, or customer premises equipment (CPE) to play a critical role in diagnosing and resolving complex customer-impacting issues.
This position sits at the intersection of Operations, Product Engineering, and Firmware Development, focusing on the investigation, replication, and root cause analysis of faults affecting home broadband routers, gateways, Wi-Fi products, Digital Voice services, and associated connected devices.
The Role
As a Technical Investigation Engineer, you will take ownership of complex technical issues from initial escalation through to root cause identification and resolution. You will recreate real-world customer issues within laboratory environments, analyse technical evidence, and work closely with development teams and suppliers to drive fixes through to deployment.
This is an ideal opportunity for someone who enjoys problem-solving, technical investigation, and getting to the root cause of challenging networking and connectivity issues.
