KAUCHE is a Japan-based social commerce platform built on Go, GCP, and Kotlin that emphasizes interactive shopping experiences. The company is aggressively scaling engineering (29 open roles) and data (19 roles) while adopting Salesforce, and internal pain points reveal a push toward ML-driven recommendations and real-time infrastructure: they're investing in recommendation engines, ML infrastructure architecture, and large-scale log data integration—but development velocity is lagging relative to growth ambitions, suggesting the product roadmap is outpacing engineering capacity.
