Headquartered in Singapore, Toku supports customers across APAC and beyond, with a growing footprint across global markets. We are looking for a hands-on L2 Support Lead to take technical and operational ownership of day-to-day L2 support across Toku’s contact centre and voice services. You will troubleshoot and own escalated issues, guide L2 engineers, drive strong ticket and SLA discipline, and coordinate effectively with customers, Engineering, Product and other technical teams. This is a technical leadership role rather than a traditional people-management position.

Technical Triage & Escalation: Diagnose issues, identify where to investigate and gather the relevant logs and technical evidence before escalating complex problems to L3, Engineering, Product or third-party vendors with clear problem statements, timelines and business impact. Incident & Service Management: Manage incident, problem, change, service request and escalation workflows end to end, applying ITIL practices and Toku’s support processes. Queue & SLA Management: Proactively monitor ticket queues, backlog, aged tickets and SLA compliance, intervening early to reprioritise, reassign, escalate or coordinate support where tickets are at risk. Problem Management & RCA: Identify recurring issues and customer-impacting trends, raise problem records, contribute to Root Cause Analysis reports and help drive corrective and preventive actions through to closure. Change Management: Raise and manage changes associated with incident and problem fixes, ensuring changes are appropriately tested, documented and progressed through the change management process. Major Incidents: Provide technical leadership during critical incidents, gathering logs, isolating faults, coordinating with relevant technical teams and providing clear updates to stakeholders. Customer Ownership: Own technical communication for escalated issues, explaining investigations, resolutions, engineering updates and release dependencies clearly to customers, including where resolution depends on other teams. Technical Leadership: Guide L2 engineers on troubleshooting approach, ticket hygiene, customer communication and escalation discipline, while reviewing ticket quality and helping the team develop stronger technical practices. Process Improvement: Identify gaps in support processes and help establish more consistent and effective ways of working across L2, improving ticket ownership, technical escalation and collaboration between support and other teams. Work Allocation & Handover: Coordinate work across the L2 support team, follow up on ticket progress and maintain effective handovers without assuming traditional line-management responsibilities such as attendance or performance management. Knowledge Management: Build and maintain SOPs, runbooks, troubleshooting guides and knowledge-base articles to improve resolution capability and reduce dependency on individual team members. Reporting: Produce daily and weekly reporting on queue health, SLA performance, aged tickets and recurring issues for the Support Manager.
