At Toku, we create bespoke cloud communications and customer engagement solutions to reimagine customer experiences for enterprises. We provide an end-to-end approach to help businesses overcome the complexity of digital transformation and deliver mission-critical CX through cloud communication solutions. Toku combines local strategic consulting expertise, bespoke technology, regional in-country infrastructure, connectivity, and global reach to serve the diverse needs of enterprises operating at scale. Headquartered in Singapore, Toku supports customers across APAC and beyond, with a growing footprint across global markets.

This is a hybrid NOC and L1 Technical Support role focused on monitoring, incident triage, and customer issue handling across Toku’s voice and messaging platform. You will be responsible for detecting issues, performing initial validation, and ensuring fast, accurate escalation while maintaining strong customer communication. The role blends system monitoring, basic VoIP troubleshooting, and application-level support in a 24/7 environment. You will be a great fit for this role if you are attentive, reliable, and comfortable working in a structured, shift-based operations environment.

• Collaboration & Escalation Coordination: Work closely with internal teams (engineering, infra, database) and external partners to resolve issues efficiently
• Documentation & Record Keeping: Maintain accurate records of customer interactions, incidents, and resolutions within ticketing systems
• Testing & Validation: Perform proactive and reactive testing of services, including validation of deployments and system changes
• Interconnection & Routing Support: Assist with basic configuration tasks such as interconnection setup and route adjustments as required
• Process Adherence & SLA Compliance: Follow defined troubleshooting procedures and ensure adherence to SLAs for response and resolution times
• Continuous Learning & Training: Participate in ongoing training to build knowledge across systems, tools, and troubleshooting techniques
• Shift-Based Operations: Work within a 24/7 shift rotation model, including weekends, with clear boundaries and no on-call responsibilities
