Technical Architect
Summary
A customer-facing technical architect/lead engineer in Tokyo who designs and leads complex enterprise system integrations on a cloud-native platform for major Japanese clients — authoring integration blueprints, running PoCs, and ensuring data-pipeline integrity, with hands-on Java/C#, relational DB, and AWS/GCP work.
Are you an architectural mastermind who thrives at the intersection of complex software delivery, hands-on engineering, and senior client consulting?
A global, tier-1 enterprise platform provider is seeking an exceptional Technical Architect / Lead Engineer to join their high-performing Professional Services division in Tokyo. In this role, you will work alongside a small team of elite consultants, business analysts, and functional experts to guide major industry clients and top-tier System Integrators (SIs) through highly complex, long-term ecosystem implementations lasting anywhere from 3 months to 2 years.
This is a unique "customer-facing engineer" role that demands excellent technical design capabilities, object-oriented programming depth, and the communication skills required to negotiate technical architecture directly with client stakeholders.
Key Responsibilities
Lead Technical Integration: Collaborate closely with Japanese enterprise clients to uncover system integration requirements, address technical bottlenecks, align designs with business goals, and author comprehensive integration blueprints.
Architect Scalable Ecosystems: Design and develop secure system integrations linking our high-scale cloud-native platform with complex internal and external legacy environments using specialized enterprise frameworks.
Manage Enterprise Data Flow: Oversee data pipeline integrity and real-time data flows between core applications and external downstream systems to ensure zero data loss.
Drive Innovation via PoCs: Execute agile Proof of Concept (PoC) initiatives to validate integration approaches, assess structural feasibility, and demonstrate technical capability to client teams.
Act as a Strategic Feedback Bridge: Serve as a key representative to the client while collaborating with global internal engineering and product management teams to share regional product feedback continuously, strengths, and upgrade strategies.
Requirements
Bilingual Capabilities: Native/Fluent Japanese (JLPT N1 level or equivalent) with a deep grasp of Japanese business practices, paired with professional English skills (TOEIC 700+ or equivalent) for internal global engineering alignment.
Proven Track Record: 7+ years of combined experience spanning hands-on software development and professional IT consulting (with a minimum of 3 years dedicated to each domain).
End-to-End Delivery Leadership: Demonstrated success acting as a technical lead for large-scale enterprise deployments, managing the complete lifecycle from requirements gathering and architecture design to code reviews, testing, and production release.
Technical Architecture Depth: 2+ years of hands-on object-oriented programming (e.g., Java, C#), 2+ years of experience with relational databases, and solid exposure to major cloud platforms (AWS or GCP).
Post-Go-Live Support: Prior experience acting as the primary technical point of contact for clients navigating version upgrades, optimization reviews, and new feature adoptions.
Preferred/Nice-to-Have Skills
Professional domain knowledge within specialized financial services or the Property & Casualty (P&C) insurance landscape (policy management, claims processing, etc.).
Familiarity with modern integration methods (REST, JSON-RPC, SOAP, MQ) and microservices architecture.
Experience with CI/CD delivery pipelines (Git, TeamCity) and observability suites (Datadog).
Benefits
Innovative Culture: A work environment that encourages individual initiative, experimentation, and continuous improvement.
Impact: The opportunity to solve real-world insurance problems at scale for some of the largest financial institutions in the world.
Autonomy: A low-bureaucracy structure that minimizes hierarchy and empowers great people to do great work.
Collaboration: Work alongside a team of elite engineers, business analysts, and global product managers in a financially strong and growing organization.
Inclusivity: Join an equal-opportunity workplace that values diversity of perspective, culture, and experience as a core pillar of success.
Competitive compensation: The compensation of this position is based on your years of experience, market standard and interview performance.
