Backend Engineer – Integrations and Distributed Systems

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.

As a Backend Engineer at Toku, you will play a senior backend-first role designing, building, and operating the backend services that power Toku’s omnichannel communications platform. This role sits within a fast-moving engineering squad responsible for integration-heavy backend systems and high-volume communication workflows across messaging, notifications, and voice services.

You will work primarily in Go, contributing to scalable event-driven systems, backend integrations, distributed services, and production-critical communication infrastructure. This role prioritises backend depth, system design capability, distributed systems thinking, and ownership over full-stack breadth.

You will be a strong fit for this role if you enjoy reasoning deeply about backend systems, solving complex production problems, and driving scalable backend solutions independently in real-world environments.
