【AI-Native Product Engineering】Support global expansion／End-to-end data analysis／Fukuoka

■What You Will Do
• Design and ship product features and internal systems
• Use AI-assisted development workflows as a default part of engineering
• Turn ambiguous problems into shipped systems
• Work across backend, frontend, data, and automation
• Improve engineering velocity and reliability
• Help define engineering standards for AI-native development

【仕事の特色】
■Role Overview
Build the product and engineering systems behind Third Hub’s global expansion.
Third Hub operates a consumer product that already serves more than 1 million users and generates over ¥1.5B in annual revenue. The product has achieved product-market fit and is now preparing for international release.
Joining now means shaping the product architecture, engineering systems, and development practices before the company scales globally.
Our Product organization is already 80% international, and English works in practice across engineering and product discussions.
At the same time, the company is redesigning its development process around AI-native engineering.

■Engineering Philosophy
At Third Hub, we believe engineers are problem solvers first.
Engineers are expected to solve problems end-to-end, not just implement tasks.
Product managers define problems.
Engineers design and solve them.
AI assists with implementation and execution.
This creates an environment where engineers focus on thinking, designing systems, and shipping impactful solutions.

■Why This Role Is Different
• Build a global product from Fukuoka
• Work inside a genuinely international engineering team
• Operate on a real product with 1M+ users
• Help define AI-native engineering practices
• Work in an environment with high ownership and decision density

■What Success Looks Like in 12 Months
• Ownership of a meaningful product or platform area
• Significant product impact through shipped systems
• AI-assisted workflows improving engineering velocity
• Clear connection between engineering work and business outcomes

■Why Third Hub
• Join before international expansion
• Work in a team already 80% international
• Tokyo-level compensation with Fukuoka lifestyle
• Short commutes — some engineers walk to the office in ~8 minutes
• Work in a true AI-native engineering environment

■Life in Fukuoka
Fukuoka is a compact and highly livable coastal city.
Many engineers live within walking distance of the office, with typical rent around ¥80,000 per month.
Compared with Tokyo, this creates a significantly higher quality of life while working on globally scaled technology.
City highlights
• Compact and walkable city
• Short commutes
• Excellent food culture
• Coastal lifestyle with nearby nature
• Lower living costs than Tokyo

■Access to Asia
Fukuoka is one of the most accessible cities in Japan for international travel.
