Forward Deployed Engineer (GenAI & Solution Architecture) | Fast-Growing AI & Cloud Transformation

Job Description

We are currently partnering with a fast-growing AI & Data consulting company in Japan that is actively expanding its Generative AI and Legacy Modernization division and is now looking for a Forward Deployed Engineer (FDE).

Please note that prior financial industry experience is NOT required.

Annual Salary: ¥8M – ¥15M JPY

Hybrid System: 3 ~ 4 remote days per week.

JAPANESE BUSINESS LEVEL REQUIRED

The company works directly with major financial institutions and enterprise clients in Japan, supporting large-scale digital transformation, Generative AI implementation, data and system modernization, cloud transformation, and legacy system transformation initiatives.

While the company currently works primarily with clients in Japan, it is beginning to expand its activities internationally, with global projects starting to emerge as part of its continued growth.

The company has two offices in Tokyo, both located in the Nihonbashi area. One serves primarily as the corporate and business office, while the other functions as the main engineering hub.

The engineering office has a highly international environment, with the large majority of its members being bilingual engineers from diverse international backgrounds. English is commonly used within engineering teams, while Japanese remains important for communication with clients and other business functions.

This combination provides an international engineering environment while offering the opportunity to work directly on large-scale transformation projects for some of Japan’s leading financial institutions and enterprise organizations.

This position is part of the team responsible for deploying and expanding a proprietary AI-powered legacy modernization platform designed to help financial institutions modernize complex enterprise systems and introduce Generative AI into real-world business processes.

As a Forward Deployed Engineer, you will work directly with clients to understand complex business and system challenges and translate them into practical technical solutions.

Unlike a traditional consulting role focused primarily on strategy and recommendations, this is a highly hands-on technical position. You will be involved throughout the entire lifecycle, from problem definition and technical validation to architecture design, implementation, testing, and production deployment.

You will work closely with client stakeholders, engineers, AI specialists, Product Managers, and consultants to design and implement solutions combining modern software architecture, cloud technologies, Generative AI, and Large Language Models (LLMs).

Projects may include legacy system modernization, AI-powered business process transformation, Generative AI applications, technical PoCs, enterprise system integration, cloud migration, and client-specific AI solution development.

This is an excellent opportunity for engineers who enjoy working at the intersection of Software Engineering, Solution Architecture, Generative AI, and Technical Consulting.

Rather than working only on predefined technical requirements, you will have the opportunity to identify client problems, evaluate technical trade-offs, select appropriate technologies, design the architecture, and implement solutions that deliver real business impact.

Key Responsibilities

• Work directly with clients to understand business processes, existing systems, technical constraints, and modernization challenges

• Translate ambiguous business and system challenges into clear technical requirements, architecture, and implementation plans

• Design and implement technical solutions using the company’s proprietary AI-powered modernization platform

• Lead technical initiatives involving legacy system modernization and Generative AI-based business transformation

• Plan and execute technical validation, prototyping, and Proof of Concept (PoC) projects

• Design system architecture and evaluate appropriate technologies based on client requirements

• Develop and implement client-specific AI applications and system functionality

• Build applications and solutions incorporating Generative AI and Large Language Models (LLMs)

• Evaluate technical trade-offs and drive technical decision-making with internal and external stakeholders

• Support projects from initial technical validation through full-scale development and production deployment

• Collaborate with client technical leaders, business stakeholders, Software Engineers, AI specialists, Product Managers, and consultants

• Identify technical insights and requirements from client implementations and provide feedback to improve the company’s proprietary AI platform and product strategy

Examples of Projects & Technical Challenges

• Modernizing large-scale legacy systems used by major financial institutions

• Designing and implementing Generative AI applications for enterprise business processes
