About the Role

We are looking for a Forward Deployed Engineer (FDE) to help enterprise customers in Japan turn generative AI opportunities into practical business outcomes.

In this role, you will serve as a technical lead throughout the customer journey—from pre-sales discussions and proof of concept (PoC) to deployment and post-implementation adoption. You will work closely with our Business Development team, customers, service partners, and global product teams to solve technical challenges and expand the use of Dify.

• Provide technical support during enterprise sales engagements, including architecture presentations, security and non-functional requirements, RFPs, and security questionnaires.
• Design and support PoCs, align stakeholders on evaluation criteria, and present results.
• Recommend system architectures and deployment approaches, including self-hosted and on-premises environments, Kubernetes, SSO, and external LLM integrations.
• Help customers design use cases, implement workflows, and expand adoption across their organizations.
• Deliver technical training and answer technical questions for service partners.
• Gather and communicate customer requirements and feedback to the global product team.

What We’re Looking For

• Native-level Japanese or equivalent proficiency.
• Approximately 3 or more years of customer-facing experience in pre-sales, systems engineering, or another technical role, including leading technical proposals or PoCs for enterprise software or SaaS.
• Experience building and operating systems with Kubernetes, Docker, and cloud platforms such as AWS, Azure, or GCP.
• Hands-on experience building LLM applications using RAG, prompt design, and APIs, or equivalent experience gained through independent learning.
• English skills sufficient to read technical documentation and communicate in writing with global engineers.
• An interest in bridging technology and business and helping customers achieve results.
• Ability to investigate open-ended problems, test solutions, and develop effective approaches.
• Willingness to share knowledge with teams and partners to make successful practices repeatable.

Nice to Have

• Experience delivering enterprise projects in industries such as finance, manufacturing, or telecommunications.
• Experience building systems in on-premises or isolated network environments and addressing security requirements.
• Contributions to open-source software or experience sharing knowledge in technical communities.
• Experience designing enablement or training programs for SIer partners.
• Business-level spoken English.
• Language skills beyond English, such as Chinese or Korean.

We believe small teams can create meaningful impact when they think deeply, use effective tools, and collaborate clearly. Our values include:

• Simple & Sincere: Communicate openly and address important issues directly.
• Hands-on: Build, test, learn, and share.
• Explore the Edge: Challenge existing approaches and explore new ideas.
• Ask Why to Bedrock: Understand underlying causes and make evidence-based decisions.
• Honor Your Commitments: Take responsibility for outcomes and build trust.

We encourage cross-functional collaboration, AI-native ways of working, and clear communication across regions.

Compensation and Benefits

• Annual salary of JPY 10,000,000–12,000,000, depending on experience and skills.
• Hybrid work arrangement; remote work is available depending on business needs. Fully remote work is not available.
• Customer-site visits as required.
• Flextime, with core hours from 10:00 a.m. to 4:00 p.m.
• Three-month probationary period.
• 10 days of paid leave granted after the probationary period.
• Support for professional learning and certifications, AI tools, health checkups, commuting expenses, fitness, and team-building meals.
