Backend Engineer – Bridge

About the role

As a Bridge Engineer, you turn product requirements coming from Korea into detailed specifications that developers can implement as-is. This is not translation or message-passing: your job is to find the ambiguities, close them with the right questions, and produce specifications that are ready to build.

This is not a documentation-only role. You stay close to the code — verifying technical feasibility and writing specs that engineers can rely on. We are looking for a backend engineer who brings both strong specification skills and hands-on engineering judgment.

Key responsibilities

• Take product requirements and finalize them into detailed English specifications, covering edge cases such as failures, duplicates, limit overruns, and cancellations
• Break specifications down into work tickets and estimate sizing
• Write detailed English specifications (APIs, data structures, edge cases), draft tickets, and estimate size
• When blocked while writing a spec, open the code directly to confirm — performing bug fixes, refactoring, or technical validation as needed
• Respond to developer questions on specifications and coordinate technical matters with the Korea tech lead

Requirements

• 3–5 years of hands-on backend development(Java/Spring preferred; Go, Node, or PHP experience also welcome)
• Working-level English — able to write documents and run meetings (we assess sentence construction, not pronunciation)
• Experience designing REST APIs and RDB schemas
• Experience organizing requirements into documents (technical specs, API docs, BRDs, etc.)
• Native Indonesian speaker

Nice to Have

• Experience in finance / fintech / payments (bank SI, payment gateway, P2P lending, etc.)
• Experience collaborating with an overseas headquarters (foreign-owned or remote team)
• Experience with issue-tracking and documentation tools (e.g., Jira, GitLab, Confluence, Notion)

What We Don't Require

• Korean — it is not needed for this role
