Our tailored solutions, including one-hour interviews, online surveys, and dedicated hands-on support, empower companies to overcome obstacles and achieve their most ambitious goals.

As a pioneer in Japan's Expert Network Service (ENS) industry, having acquired Coleman with the aim of becoming a Global Knowledge platform,we have just entered an ambitious new AI chapter: automating the diffusion of unique human insights that major LLMs haven't captured yet.

To achieve this, we are seeking Software Engineers who can contribute to both engineering and architecture design by taking charge of designing and implementing autonomous AI agents leveraging predictive and generative models.

We are looking for Mid-level and Senior Talent. VisasQ is a publicly listed company (founded in 2012 and still led by our founder/CEO) that operates with a fast-paced startup/scale-up mindset. We are actively strengthening our core team in Japan while collaborating with our engineering presence across the US and Europe.

• Collaborating with cross-functional and geographically distributed teams (including Co-CTOs, Team Leads, PdMs, and BizDev) across Japan, the US, and Europe to drive global ENS product strategy.

• Designing, implementing, and maintaining scalable and resilient backend systems and APIs to support core matching, search, and next-generation AI-driven features.

• Collaborating on the integration and deployment of autonomous AI agents and LLM orchestration, ensuring optimal backend architecture and system latency.

• Promoting a full-cycle development culture by taking ownership of the entire lifecycle, including automated testing, CI/CD pipelines, code reviews, and production operations/maintenance.

• Refactoring legacy code, optimizing database performance, and actively resolving technical debt to ensure long-term system maintainability and scalability.

• Direct Business Impact: You will play a pivotal role in completely rebuilding our core search and matching infrastructure with AI, working with a massive asset of 800,000+ experts and directly driving revenue growth.

• Multi-Phase Product Lifecycle: Experience everything from scaling internal AI products (1-to-10 and 10-to-100 phases) to spearheading upcoming greenfield user-facing projects from scratch (0-to-1 phase).

• Truly Flat & Global Collaboration: Work in a barrier-free environment where engineers, designers, and business members align seamlessly. Frequent collaboration with US and European hubs offers deep global career exposure right here in Tokyo.
