Integration Manager (Tokyo, Japan)
Quick Summary
ABOUT YOU We are looking for a talented Integration Manager who can work with new and existing game partners and help get out tools, products, and services working inside their games.
-
Lead and confidently run client meetings, calls, and technical demos independently, without needing a BD or CS lead to carry the conversation
-
Act as the primary technical point of contact during pre-sales and onboarding, scoping integration requirements and setting realistic expectations
-
Present technical concepts clearly to both technical and non-technical stakeholders (engineers, producers, executives)
-
Guide partners through API integration, including authentication, request/response structures, JSON payloads, and webhook configuration and delivery
-
Diagnose issues using data dumps, technical logs, and API traces; distinguish integration errors from platform bugs
-
Write and interpret basic scripts or API calls (e.g., via Postman, curl) to reproduce and isolate client-reported issues
-
Document issues concisely and completely enough for engineering to act on without back-and-forth
-
Know when to resolve an issue directly versus escalate to Engineering, Product, or Support, and manage that handoff cleanly
-
Serve as the communication hub between Client, Business Development, Customer Success, and Development teams, ensuring nothing gets lost in translation between technical and commercial priorities
-
Provide clear, well-organized status updates to internal stakeholders and clients throughout the integration lifecycle
-
Maintain accurate documentation in Jira, Confluence, and related tools
Bachelor's degree (or equivalent experience) in a related field
3+ years of experience in technical integration, solutions engineering, or a client-facing technical role
Demonstrated ability to lead client meetings and presentations independently — this is not a support-only or backend role
Working knowledge of REST APIs, JSON, and webhooks; able to read API documentation, interpret payloads, and troubleshoot integration failures independently
Comfortable using tools like Postman (or equivalent) to test and debug API calls
Near-native fluency in both Korean and English, written and verbal; able to confidently lead client presentations and meetings and write professional business emails in either language without support (daily cross-team communication is in English)
Proven customer service or client relationship experience
Comfortable working with high autonomy, shifting priorities, and a significant workload
Strong attention to detail and time management
Prior experience in the gaming industry, payments, or fintech
Experience with Confluence, Jira, and G Suite
Prior experience at a foreign or international company, or working across time zones with global teams
Genuine interest in games (as a player) and the gaming industry
