A Japan-originated global Web3 technology company building next-generation blockchain infrastructure, decentralized applications, and on-chain products. With strong partnerships across major global enterprises and financial institutions, it is focused on bringing blockchain technology into mainstream use and building the infrastructure for the next generation of the internet.
■ Your Role and Responsibilities
● Define QA standards, release criteria, and quality metrics.
● Design, build, and maintain scalable E2E automated test frameworks (e.g., Playwright) (80–90% of the role involves building automation).
● Validate trading logic: execution paths, price impact, fee calculations, and thousands of user paths (Strium).
● Modernize, optimize, and expand existing E2E testing infrastructure.
● API testing: verify consistency between backend responses and frontend behavior.
● API load and stress testing designed for high-throughput environments.
● Design reproducible test environments and test data.

● Ability to work autonomously as the sole QA professional for a product or team. Ability to proactively clarify requirements across teams, even when specifications are ambiguous
● Experience taking ownership of defining quality standards and test strategies, and driving the team to implement them (organization size is not a factor; the role requires building systems/processes rather than simply executing pre-defined tests)
● English proficiency beyond a conversational level (English is the official company language; native-level fluency is not required)
● Curiosity and a drive to quickly learn and assimilate knowledge in unfamiliar domains (prior blockchain experience is not required)
■ Additional Preferred Qualifications
● Experience with E2E automation for exchanges, securities, or financial systems
