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
CyberAgent's Media division is hiring a Feature Flag and A/B Test Engineer for Bucketeer, the feature-flag management and A/B testing system that began at ABEMA and was released as open source in 2022. It now sits in the group's Developer Productivity office, which spreads trunk-based development and feature-flag practice across CyberAgent.
The engineer develops Bucketeer as both an internal SaaS and an open-source product, from heavy-traffic request handling and data infrastructure to the application and the client SDKs. The role carries product ownership, including shaping the strategy and roadmap to make it a leading product in a field with no clear standard yet.
Applicants need to enjoy supporting developers and be interested in developer-facing solutions, at least three years of designing and developing web services (maintenance alone does not count), experience building and running public cloud such as GCP or AWS, and the ability to plan product growth with ownership. Preferred are trunk-based development and A/B testing experience, SRE and DevOps experience, at least a year of Go, Kubernetes knowledge, open-source work and experience speaking at communities or conferences.
