Adora株式会社のFlutter Engineerの求人

We are hiring two Flutter Engineers to own the mobile experience across Kodomamo Family and Kodomamo School. You will build new features, fix customer-reported issues, and help shape the technical direction of our apps — working closely with the CTO and a small, senior-heavy team.
Our apps directly protect children in tens of thousands of families and schools across Japan. The code you write matters.

What You'll Do

• Build and ship cross-platform features for Kodomamo Family and Kodomamo School (Flutter/Dart, iOS & Android).
• Collaborate with the CTO and backend engineers to scope, design, and deliver new product capabilities.
• Triage and resolve customer support queries that require engineering investigation or code changes.
• Write clean, well-tested Dart code and participate actively in code reviews.
• Contribute to architectural decisions — we want engineers who have opinions about how things should be built.

Tech Stack

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

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.
