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.


Job Responsibilities

1. Production-system maintenance

  • Take over maintenance and iteration of TESO Dock (replenishment/procurement/supplier portal), TESO Dashboard (group ops platform), and Teso Tools.
  • Build docs, monitoring, and on-call rotation to remove single-maintainer risk.


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.


Education
Bachelor’s degree or above; computer science or software engineering preferred.

Professional Experience
3+ years in full-stack development; experience inheriting and improving existing codebases preferred.

Knowledge & Skills
Masters the full SDLC (requirements, design, build, test, deploy, operate); TypeScript/JavaScript and Python; Next.js/React, Node.js, PostgreSQL; REST APIs and cloud deployment (AWS); proficient in vibe-coding workflows and AI coding assistants (any of Claude Code/Cursor/GitHub Copilot) with hands-on AI-driven development experience.


Core Competencies

Highly accountable; comfortable taking over legacy code; fast business comprehension; embraces AI-driven development and uses tooling to multiply output.


Compensation

$110,000-$140,000 per year + Quarterly Performance Bonus
