[Technical Environment]
- Language: TypeScript
- Backend: Node.js, Express
- Database/Auth/Storage: Supabase, PostgreSQL
- Infra: Docker, Google Cloud Run, Cloud Tasks, Secret Manager

[Work Style]
Agentic Development. We actively utilize AI/Agentic development tools.
Rather than just writing code line by line, we value the ability to accurately define problems, quickly implement solutions using AI tools, validate results, and organize them into operational code.
The responsibility for AI-generated results lies with the developer. You must be able to directly validate security, data integrity, error handling, testing, and operational risks.
[Not Suitable For]
- Those who find it difficult to start development without a predetermined project plan
- Those who use AI tool outputs without validation
- Those who feel burdened by rapid priority changes and high workload
- Those who find it difficult to share challenges or risks during the development process
[What We Value]
We look at problem-solving methods and execution speed rather than years of experience. We are looking for a backend engineer who actively participates in defining the execution boundaries of the product, not just a simple API implementer.
The environment actively utilizes AI/Agentic development tools and seeks someone who can implement quickly and validate accurately.
