Job Description:
Job Description
Own the stability, maintenance, and evolution of internal commerce systems built on Go (Golang).
Keep production systems running reliably: Order Management, Stock Management, Warehouse, Packaging, Reporting.
Handle bug fixes, performance tuning, and incident response.
Maintain integrations with Shopee, TikTok Shop, Lazada, Tiki, and brand websites (webhook + REST APIs).
Collaborate with Korean and overseas development partners to redesign and extend the current system into an ERP-class platform.
Translate business requirements (from Operations, Finance, Warehouse, Marketing) into clear technical specs.
Drive architectural improvements: DB normalization, multi-DB strategy, observability, high availability.
Use AI development tools (Claude Code, Codex, Copilot, or equivalent) as a core part of daily workflow.
Apply AI to accelerate code review, debugging, documentation, and feature development.
Plan, estimate, and track your own development work.
Maintain technical documentation (architecture, runbooks, SOPs, change logs).
Coordinate with external development partners: define scope, review deliverables, manage timelines.
If business growth requires more development capacity, help scope and onboard additional internal or external developers.
Requirements
5+ years of backend software engineering experience.
Strong proficiency in Go (Golang) - or strong experience in another modern backend language (Java, Python, [protected info]) with demonstrated ability to ramp up on Go quickly.
Solid SQL and relational database experience (MySQL preferred).
Comfortable reading, understanding, and refactoring legacy code.
Hands-on experience with Docker, Linux, and VPS/cloud deployment.
Ability to analyze a system end-to-end and identify weak points - not just write features.
Working business English (written + spoken) for direct collaboration with Korean and overseas partners.
Strongly Preferred: Hands-on experience using AI coding tools in real production work.
Strongly Preferred: Experience integrating with e-commerce platform APIs (Shopee / TikTok / Lazada / Tiki).

Strongly Preferred: Experience managing or working with external development partners.
Additional: Background in retail, e-commerce, or logistics systems.
Additional: Experience with ERP-class systems.
Who You Are: Hands-on, not a delegator. You write code yourself. You debug production issues yourself.
Who You Are: Analytical. You understand systems before you change them.
Who You Are: Pragmatic. You ship working solutions over perfect ones.
Who You Are: Accountable. When something breaks, you own it and fix it.
Who You Are: AI-native mindset. You see AI tools as leverage, not a threat.
