- Experience in a technical customer-facing role such as Solutions Engineer, Technical Account Manager, Implementation Engineer, Partner Engineer, Sales Engineer, Integration Engineer, or similar. - Strong understanding of APIs, especially REST APIs, authentication, request/response structures, logs, error handling, and integration testing. - Ability to communicate clearly with both technical and non-technical stakeholders. - Experience working with product and engineering teams to resolve partner or customer issues. - Ability to translate ambiguous partner requirements into structured technical tasks. - Strong troubleshooting ability and comfort working with logs, API payloads, test environments, and issue reproduction steps. - Professional English communication ability.

- Experience in travel, hospitality, OTA, channel manager, PMS, booking engine, payments, or distribution platforms. - Experience working with Japanese hotels, travel agencies, OTAs, or enterprise partners. - Experience with supplier integrations, reservation systems, inventory systems, pricing systems, billing, or reconciliation workflows. - Familiarity with Postman, Swagger/OpenAPI, SQL, JSON, webhooks, API gateways, or observability tools. - Japanese language ability. - Experience working in startup, early-stage product, or platform launch environments. - Experience creating technical documentation or partner-facing integration guides.

You are someone who can sit between business, product, engineering, and external partners without getting lost in ambiguity. You do not need to be a full-time software engineer, but you should be technical enough to understand API behavior, diagnose integration issues, communicate clearly with engineers, and guide partners through implementation. You should be comfortable working in an environment where processes are still being built. This role requires ownership, clear communication, structured thinking, and the ability to help create repeatable partner onboarding and support systems from the ground up.
