Company Description

In just 13 months since founding, the company hit a $2B valuation and raised $286M in total funding. Its B2B customer-service AI agent platform is already deployed across enterprises in 30+ countries.

The client is opening the Japan market and looking for the first member to build it from zero. Working directly with the European HQ's C-level, you'll design and build an entire country's business from the ground up — the closest thing to founding, with the leadership mandate to match. The CTO directly solves the most critical problems facing customers and the product.

What You'll Do

• Lead the technical side of sales: join early-stage conversations, present demos, and guide architecture and security discussions.
• Act as hands-on engineering lead — shipping code, building integrations, and setting high quality standards.
• Build and lead a high-performing technical team across engineering, integration, and pre-sales — laying the technical foundation of the Japan entity yourself.
• Drive customer integrations end to end, from scoping to deployment of AI agents, ensuring production accuracy.
• Gather customer feedback, localize the product, and represent regional needs directly to the global Product team.
• Serve as the local technical point of contact, building partnerships and handling escalations.

Who You Are

• 8+ years of hands-on software engineering — you've built things that actually shipped.
• Proven track record in pre-sales, solution architecture, or complex technical implementations.
• Customer-facing background (Field CTO, Solutions Architect, Deployed Engineer) — you speak both tech and business fluently.
• Strong leadership DNA, ideally at Director, VP, or Founder level.
• Excellent English, plus fluency in Japanese, to lead technical and business discussions with multinational clients.
• Comfortable in a zero-to-one environment — building the plan, the team, and the system from scratch.
• Bonus: you've thrived in a fast-moving startup where speed and ownership matter more than titles.

Perks & Benefits

• Global Top-tier compensation plus a next-gen founding-member equity package.
• Global stage: Japan-based, with regular exchange with the European global HQ and direct C-level collaboration.
• Flexible remote work and world-class wellness benefits.
• A rare scale-up experience: opening an entire market at the frontier of enterprise AI adoption.
