About Global 4
At Global 4, we Love Tech. We provide a wide range of market-leading telecom, connectivity, cloud, and IT services to businesses across the UK. Our vision is to solve our customers' technology challenges by advising, implementing, and supporting the right solutions with best-in-class service excellence.
Purpose of the Role
As a 2nd Line Technical Support Engineer, you will bridge the gap between initial triage and deep infrastructure/vendor support. You will act as the key escalation point for our 1st Line team, taking ownership of complex data, broadband, and Unified Communications (UCaaS) faults. Operating in a fast-paced environment, your goal is to troubleshoot technical issues efficiently, hit strict Service Level Agreements (SLAs), and communicate technical resolutions in simple, clear terms to our customers.
Key Responsibilities

Provide 2nd Line Technical Support for escalated incidents across broadband, VoIP, and network infrastructure, ensuring timely and effective resolution with minimal supervision.

Perform advanced diagnostics and fault isolation using tools such as packet capture analysis, SIP tracing, and router configuration interfaces (e.g., CLI, GUI).

Troubleshoot and resolve complex service-affecting issues including latency, jitter, call routing anomalies, and authentication failures across multi-vendor platforms.
-
Liaise with third-party providers (e.g., carriers, hardware vendors, hosted service platforms) to escalate and coordinate resolution of external faults.
-
Maintain comprehensive and structured ticket documentation, ensuring all actions, timestamps, and communications are logged in accordance with internal standards and regulatory frameworks (ISO 27001, GDPR).
-
Conduct validation testing post-resolution, including line tests, QoS verification, and service restoration checks to ensure no residual impact to the customer.
-
Proactively monitor ticket queues and system alerts, triaging based on severity, SLA targets, and customer impact to maintain operational efficiency.
-
Contribute to root cause analysis and problem management by identifying recurring faults and proposing long-term fixes or process improvements.
-
Collaborate with engineering, provisioning, and service delivery teams to ensure seamless handovers and coordinated resolution of cross-functional issues.
-
Act as a technical escalation point within the team, supporting junior staff and sharing expertise through documentation, training, and peer mentoring.
-
Demonstrate a strong working knowledge of IP networking (DNS, DHCP, NAT, VLANs), SIP protocol behaviour, and broadband technologies (FTTC, FTTP, ADSL).
-
Translate complex technical findings into clear, customer-friendly language, ensuring clients are informed and reassured throughout the support lifecycle.
