Build AI Worker VoiceAgent’s web frontend, designing visual interfaces and admin features, selecting architecture, and delivering releases with TypeScript and React in a hybrid office/home role.
About this role
WinTicket, the CyberAgent subsidiary behind the WINTICKET online betting service for keirin and auto racing, hires a Backend Engineer. In its seventh year as the industry leader, the service is run by a small server-side team of about ten that owns everything about one service's backend: new features, infrastructure operation and customer-support issues.
The engineer mainly writes Go applications, working across fields and infrastructure as needed, and covers the whole flow from design to implementation, release and operation, including database tuning, video delivery, links to external systems such as payment and racing-organiser systems, and machine-learning models that predict race results and detect fraud. The architecture uses microservices, clean architecture, DDD and a monorepo on GCP, Kubernetes and Cloud Spanner, with Go, gRPC and Terraform.
Applicants need three or more years of web service design and development (maintenance only does not count), one or more years on a high-traffic service and in Go, infrastructure and networking knowledge and DevOps practice. Kubernetes, AWS or GCP, container operation and public-gambling domain knowledge are preferred.
