Product Engineer

About the Job
TableCheck, Japan’s leading restaurant reservation management platform, is seeking a Product Engineer specializing in custom backend solutions for enterprise clients. This hybrid role combines technical development expertise with project and stakeholder management responsibilities to drive integration and backend initiatives from start to finish. As a Product Engineer, you will lead the full lifecycle of backend projects — gathering requirements from clients and internal stakeholders, designing technical architecture, implementing third-party integrations, and iterating based on feedback. You’ll serve as both the technical executor and the integration expert for our enterprise-facing backend infrastructure.
TableCheck has embraced remote work. As such, communication and documentation are in our blood. We look for and write about signals in the noise which enables us to constantly learn and adapt, and we expect members of our teams to constantly follow up with questions and updates to keep everyone in the loop. You will be working closely with members in Japan and supporting enterprise clients across Japan and Southeast Asia, so we require that you work during Japanese business hours.
