Job description

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 role is a hands-on backend engineering position focused on the services that power Toku’s communications platform. You will primarily work in Go to maintain and evolve backend APIs and platform modules supporting telephony capabilities such as call flows, IVR logic, and messaging services. A key part of the role involves understanding and improving existing platform services while contributing to ongoing modernisation efforts, including architectural improvements and the evolution toward event-driven systems. You will thrive in this role if you enjoy reasoning through complex systems, improving production software, and contributing to the long-term evolution of a large-scale communications platform.

What you will be doing

Backend services & APIs: Build, maintain, and improve backend services and APIs that power Toku’s communication platform.
Telephony platform features: Develop and support backend modules related to call flows, IVR logic, and inbound and outbound telephony functionality.
Platform maintenance & improvement: Investigate issues, resolve defects, and incrementally improve existing services to strengthen system reliability and stability.
Event-driven systems: Develop and maintain backend services that use event-driven architecture, including Kafka and AWS SQS.
Cloud platform development: Design and operate backend services on AWS using cloud-native design principles.
Database integration: Implement backend data interactions using relational databases, primarily MySQL.
Production ownership: Monitor system behaviour, review logs, troubleshoot incidents, and maintain reliable production services.
On-call support: Participate in an engineering on-call rotation (approximately one week every six weeks) responding to production incidents raised by NOC or internal teams.
Platform modernisation: Contribute to ongoing improvement and redesign of platform services, supporting architectural evolution and increased adoption of event-driven systems.
Engineering collaboration: Work closely with engineers across product engineering squads to deliver platform improvements and support adjacent initiatives.
