Position Overview

The Full-Stack Developer builds and guards the company's in-house systems, maintaining TESO Dock, TESO Dashboard, and TESO Tools in production while building new systems and features per roadmap priorities.

This role is more than writing code: it owns the stability, release quality, and technical debt of the in-house systems as the store network scales.

2. Roadmap development

• Build the product tax management system, automated KPI dashboards, ticketing system, and HRIS modules per P0/P1 priorities.
• Contribute to the in-house POS prototype and TESO Store pilot evaluation.

3. AI-driven development

• Drive requirement breakdown, code generation, testing, and refactoring with AI coding tools (Claude Code, Cursor, GitHub Copilot), materially raising delivery speed.
• Build the team's AI development workflow (vibe coding), prompt library, and usage standards; evaluate and adopt new tools.

4. Engineering quality

• Follow coding standards, reviews, CI/release process - AI-generated code goes through the same review and test gates.
• Write tests and docs; control technical debt.

5. Business collaboration

• Clarify and break down requirements with the manager and stakeholders.
• Follow adoption feedback and fix defects post-launch.
