Deliver training on new tools, technologies, and operational practices to internal staff and managed service partners. Authorise and manage security access for vendors and managed service partners.

Audit and fine-tune network alarms to improve monitoring effectiveness and support automation. Provide input into tool and platform strategy to ensure alignment with operational outcomes. Act as the primary technical escalation point and decision-maker during shifts when operational leaders are unavailable. What makes you perfect for the role?

In-depth expertise in Unix/Linux operating systems and telecom signaling protocols, including SS7, Diameter, and SIGTRAN standards, is essential. Working knowledge of database technologies—both relational (e.g., Oracle, PostgreSQL, MySQL, MariaDB) and NoSQL (e.g., MongoDB, Cassandra)—is highly desirable and considered an advantage. Strong understanding of service operations, including performance and fault management. Demonstrated ability to lead and resolve high-severity incidents and cross-domain technical issues.
