QA Engineer

About Us

Cogent Labs is a Tokyo-based AI startup.

Since our founding in 2014, we have aimed to "make AI a technology that is useful in the real world," and have been developing AI products that support the operational efficiency of companies.

Our flagship product , SmartRead, is a service that automates document processing using AI and is used by many companies. Currently, we are also working on developing workflow automation and new AI products, including SmartFind , which utilizes search and conversational AI.

A key characteristic of Cogent Labs is that it researches and develops not only its applications but also the underlying AI models in-house. They utilize cutting-edge AI technologies, including their unique large-scale document models, to solve real-world business challenges.

Our employees come from diverse national and regional backgrounds, and our engineering, product, and business teams work closely together to advance product development.

Recruitment background

Cogent Labs continuously develops and operates multiple AI products.

As a product grows, the role required of quality assurance is also expanding.

The QA organization we aim for is not one that is solely responsible for pre-release testing.

We prioritize quality from the requirements definition and design review stages, working together with the development team to create that quality. We also strive for continuous quality improvement by appropriately combining manual testing and test automation.

To further strengthen our quality assurance system, we are recruiting new QA engineers.

About this position

In this position, you will be responsible for all aspects of quality assurance for AI products.

My responsibilities are not limited to just conducting tests.

• Requirements Review
• Test planning and design
• Manual testing
• Test Automation
• Quality checks before and after release
• Quality improvement activities

You will be involved in the entire QA lifecycle, including tasks such as those mentioned above.

As our service is for Japanese customers, communication in Japanese is important. On the other hand, our engineering team consists of multinational members, and we use both Japanese and English internally.

At the time of joining the company, conversational English skills are sufficient. You will naturally become accustomed to communicating in English through your daily work.

We value a commitment to creating better quality more than years of experience.

We welcome individuals from junior to middle levels who are eager to learn, can cooperate with a team, and can act proactively.

The appeal of this job

Quality that "creates" quality

QA is not just about checking quality at the end of the development process.

At Cogent Labs, we value designing quality itself by collaborating with the development team from the requirements review and design stages.

We work as a team, constantly thinking about "how we can make the product even better."

We value both manual and automated testing.

We don't believe that automation alone is the only value of QA.

We achieve high quality by appropriately combining exploratory testing, manual testing involving specification understanding, and automated testing.

We are also actively promoting UI test automation using Playwright.

A new challenge: AI × QA

New technologies, including generative AI, are bringing about significant changes in quality assurance (QA).

At Cogent Labs, we are actively working on new approaches to QA, such as using AI for test support and quality improvement.

This is the perfect environment for those who want to take on new challenges while learning new technologies, not just traditional QA.

A culture that welcomes suggestions for improvement

While respecting existing QA processes, we actively welcome suggestions for better methods.

You can propose your own ideas to the team regarding QA processes, automation, quality metrics, and more, and actually put them into practice.

Global engineering team

The development team includes members from various countries and regions, not just Japan.

This is an environment where you can collaborate with engineers from diverse backgrounds to develop AI products together.
