Adora株式会社のBackend Engineerの求人

We are looking for a Backend Engineer to own the next layer of Adora's platform. The immediate priority is building out utility integrations — WhatsApp, Instagram, and other communication channels — that extend how Kodomamo connects with users and surfaces risk signals. You will have real ownership over backend architecture and work closely with the CTO on system design.

What You'll Do

• Design, build, and maintain backend services and APIs in Go and TypeScript.
• Lead development of platform integrations with third-party services (WhatsApp Business API, Meta Graph API, etc.).
• Collaborate with Flutter engineers on mobile-backend contracts and API design.
• Write well-tested, maintainable code and contribute to thorough code reviews.
• Diagnose and resolve production issues, ensuring high reliability and performance.
• Contribute to backend architecture decisions as the platform scales.

Tech Stack

• Backend: Go, TypeScript
• Infra: Kubernetes, GCP
• Mobile: Flutter

Our Culture

• Small, high-calibre team — average age 26–27, many with overseas study or work experience.
• English is our official working language (Japanese also spoken).
• Fully remote & full-flex — we have a Kinshicho (Tokyo) office, but you can work from anywhere.
• Flat org, low hierarchy — everyone talks directly to the CTO and CEO.
• Serious mission, startup energy — we care deeply about social impact and move fast.
