Senior Software Engineer in Test (Global Product Team)

In this position you’ll be joining a team that functions as an independent startup within CADDi. You’ll be creating a new application based on top of our core platform, CADDi AI Data Platform, which manages large archives of engineering drawings, documents, and supply-chain data.

We have developed an initial version of the product and are now preparing for its official release. As we move toward full-scale launch and rapid iteration, ensuring product quality, stability, and test automation coverage is a top priority.

This role is ideal for a QA engineer who enjoys hands-on testing, automation, and improving delivery speed through engineering-driven quality practices.

Expected Role

As a QA Engineer in the Incubation team, you will work closely with the QA Lead and engineering team to design, implement, and execute QA processes and automation frameworks. Your focus will be on:

• Building and improving automated and manual test execution systems
• Increasing test coverage and reliability across the product
• Embedding quality into CI/CD pipelines
• Supporting fast-paced release cycles through scalable QA practices

Responsibilities

• Design, build, and evolve scalable automated test frameworks and infrastructure across multiple layers (unit, integration, E2E)
• Define and drive test strategy, including test pyramid design, coverage goals, and quality metrics aligned with product risk
• Develop and continuously improve test plans and test cases in close collaboration with engineers, product managers, and QA stakeholders
• Lead defect management: identify, reproduce, prioritize, and perform root cause analysis with clear, actionable reporting
• Drive improvements in system testability by influencing architecture, design patterns, and development practices
• Establish and promote QA standards, best practices, and processes to improve overall engineering quality and velocity
• Optimize CI/CD pipelines to ensure reliable, fast, and scalable test execution
• Mentor and guide engineers in testing practices, fostering a quality-first mindset across the team
• Evaluate and introduce appropriate tools and technologies to enhance test automation and QA efficiency
• Balance and strategically improve manual and exploratory testing where automation is not yet effective

What You will Gain

• Hands-on experience building QA automation for a new global SaaS product
• Opportunity to shape QA engineering practices in a fast-growing incubation team
• Exposure to modern cloud-native architectures and distributed systems
• Close collaboration with highly skilled engineers in a product-driven environment
• Experience in scaling QA from startup phase to global product release

Requirements

• +5 years of experience leading quality assurance activities based on strong expertise in QA engineering
• 7+ years of hands-on experience in software development
• Hands-on experience building or maintaining automated test suites
• Experience with test design, test execution, and defect management
• Understanding of QA methodologies

Nice to have

• Hands-on experience in development and QA for large-scale systems involving multiple teams and stakeholders
• Experience performing QA in Agile development environments
• QA experience for Web applications, SaaS products, and in startup environments.
• Professional experience as a software engineer
• Fluent business-level Japanese communication skills
  • Examples include:
    • Japanese Language Proficiency Test N2 level or equivalent, or
    • Approximately 3 years of professional work experience in a Japanese-speaking environment
