QA Engineer, Workflow Platform Development Division, Tokyo

As our services scale in complexity and user impact, we need a QA Engineer who can own end-to-end quality, from strategy definition to production release. You will help us build modern, automated quality practices that keep pace with fast delivery cycles while maintaining high reliability.

This role is key to establishing robust QA foundations that can scale across multiple products and teams.

Job Satisfaction and Experience Gained

• In this role, you will have the opportunity to design and drive the quality strategy for AI-enabled products that impact a large and growing user base.
• You will gain hands-on experience in building modern test architectures that integrate automation, AI tools, and shift-left practices.
• By collaborating with cross-functional teams across product, engineering, and DevOps, you will develop strong leadership and stakeholder management skills.
• You will also be at the forefront of applying AI-driven tools and methodologies to improve software quality and delivery efficiency.

Expected Role

• You are expected to act as a central owner of quality for one or more products, taking responsibility for defining what “good” looks like and ensuring releases meet that bar.
• You will proactively identify quality risks, propose pragmatic mitigation strategies, and ensure they are reflected in test plans and release criteria.
• As a senior member of the team, you will help shape QA standards, workflows, and tooling that can be replicated across multiple teams.
• You will also serve as a bridge between technical and non-technical stakeholders, translating quality insights into clear business impacts.

Expected Mindset

• We expect you to have a strong sense of ownership and accountability for product quality, treating defects and incidents as learning opportunities for systemic improvement.
• You should be comfortable challenging existing processes and suggesting better approaches based on data and best practices.
• A collaborative and teaching-oriented mindset is essential, as you will be mentoring other engineers and promoting a culture of shared quality responsibility.
• Curiosity about new technologies, especially AI-related tools and methods, and a willingness to continuously refine your approach are highly valued.

Who We’re Looking For

• We are looking for someone who is passionate about building high-quality, reliable products and who sees QA as a strategic function rather than a final checkpoint.
• You should enjoy working closely with cross-functional teams, facilitating discussions, and aligning diverse stakeholders around quality goals.
• You are comfortable working in an evolving environment, where requirements and technologies change, and you proactively adapt testing strategies accordingly.
• If you are motivated by the opportunity to shape QA practices in an AI-driven, cloud-native environment, you will thrive in this role.
