Integration Manager (Tokyo, Japan)

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. The ideal candidate will possess a blend of technical and people skills, reasonable design and UX sensibility, and some understanding of how payments in gaming "should" work. You should have experience playing games. Applicants should expect to assist developers and technical personnel rapidly debug their technical issues and escalate or transfer as necessary - for this reason, ability to quickly diagnose basic technical issues and provide proper documentation is a must.

If you’re passionate about driving business growth, supporting game developers, and expanding the reach of innovative gaming solutions, we would love to hear from you!

This role will be based out of our Japan office but can be hybrid or fully remote depending on the situation.

At Xsolla, we believe that great games begin as ideas, driven by the curiosity, dedication, and grit of creators around the world. Our mission is to empower these visionaries by providing the support and resources they need to bring their games to life. We are committed to leveling the playing field, ensuring that every creator has the opportunity to share their passion with the world.

Headquartered in Los Angeles, with offices in Berlin, Seoul, and beyond, we partner with industry leaders like Valve, Twitch, and Ubisoft to clear the paths for innovation in gaming. Our global reach spans over 200 geographies, offering more than 700 payment methods in 130+ currencies.

• 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)

• 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
