We are developing a new B2B platform that powers travel distribution, supplier integrations, pricing optimization, and booking infrastructure for partners around the world.

This is a foundational role for someone who wants to help design and lead the engineering architecture behind a high-impact travel technology platform from an early stage.

Responsibilities

• Own and guide the technical architecture of KabuK Exchange’s platform services.
• Lead backend and platform engineering decisions across internal and outsourced engineering teams.
• Translate product requirements and business goals into scalable technical designs.
• Define service boundaries, API design principles, integration patterns, and engineering standards.
• Guide architecture for core travel platform domains such as pricing, inventory, booking, reservations, supplier integrations, channel distribution, billing, and payments.
• Review technical designs, code quality, implementation plans, and delivery risks.
• Work closely with Product Managers, QA, and leadership to improve requirements quality, delivery predictability, and system reliability.
• Help establish engineering practices around documentation, testing, observability, release management, and incident prevention.
• Mentor engineers and help raise the technical bar across the team.
• Provide light management, technical coordination, and delivery guidance across internal engineers and external development partners.
• Support hiring and future team-building as the platform organization grows.
• Help identify technical risks early and propose practical solutions before they become delivery or operational issues.
• Partner with the Head of Platform on technical roadmap planning, architecture prioritization, and long-term platform strategy.

Qualifications

• Strong backend or platform engineering experience, ideally in a senior engineer, tech lead, platform lead, or engineering lead role.
• Experience designing and building distributed systems, APIs, integrations, or high-transaction backend services.
• Ability to own architecture decisions and communicate tradeoffs clearly to both technical and non-technical stakeholders.
• Strong understanding of backend engineering principles, system design, data modeling, reliability, and maintainability.
• Experience working in or around a C# / .NET environment, or the ability to become productive in one quickly.
• Experience with cloud-native systems, preferably AWS.
• Strong API design and third-party integration experience.
• Ability to lead technically across a mixed team of internal engineers and outsourced development partners.
• Comfortable working closely with product, QA, and business stakeholders.
• Conversational English communication ability.
• Based in Japan and able to work closely with teams and leadership in Japan time zones.

Requirements

• Experience with Go, Java, or other modern backend languages.
• Experience modernizing or evolving a platform from an existing .NET/C# foundation toward a broader service-oriented or cloud-native architecture.
• Experience in travel technology, hotel distribution, OTA systems, channel managers, booking engines, marketplaces, payments, billing, fintech, logistics, or other complex transaction platforms.
• Experience with event-driven architecture, message queues, asynchronous processing, or microservices.
• Experience with pricing, inventory, reservation, payment, ledger, reconciliation, or financial correctness systems.
• Experience working with React-based frontend teams.
• Experience improving engineering processes for hybrid teams, outsourced engineering teams, or early-stage platform organizations.
• Experience building systems where reliability, operational visibility, and financial correctness are critical.
• Japanese or Korean language ability is welcome, but not required.

Benefits

• Help build a foundational B2B2B travel distribution platform from an early stage.
• Work directly with platform leadership and influence core technical direction.
• Own architecture across critical travel commerce domains including inventory, pricing, booking, integrations, billing, and payments.
• Join a team focused on connecting Japanese hospitality supply to broader global distribution.
• Play a major role in shaping engineering standards, team structure, and platform scalability.
• Work on complex platform problems involving travel inventory, supplier connectivity, pricing logic, reservation reliability, and financial workflows.
• Join a role with meaningful ownership, visibility, and long-term growth potential.
