  • Client-Facing & Pre-Sales

    • 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)

      • Technical Integration & Troubleshooting

      • 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

        • Cross-Functional Communication

        • 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

    • 必須要件 / Qualifications

  • 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

    • 歓迎要件 / Preferred

  • 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

    • (English follows Japanese)
