WHO ARE WE LOOKING FOR?
We are looking for the first dedicated QA Engineer for our AI products—someone who understands and embraces the uncertainty and non-deterministic nature of LLM-based systems, and who is interested not only in testing quality, but in making quality work as a sustainable system.
In this role, you will go beyond executing individual test cases. A key mission is to standardize and automate evaluation workflows so that user feedback and evaluation results continuously feed into product quality improvements. You will work closely not only with product development teams, but also with MLOps and data engineers, bringing a QA perspective to redesign, implement, and operate the entire feedback loop.
In particular, we expect you to take ownership of building the first practical quality feedback loop led by QA, even in situations where feedback from real users is limited or not yet sufficiently established.
This position reports to the function leader and offers a hybrid work arrangement. Additionally, there are business trips to Woven-City several times a month.
RESPONSIBILITIES
Define quality dimensions for AI products, including accuracy, consistency, safety, fairness, and UX
Conduct scenario-based testing, exploratory testing, and red teaming
Analyze LLM outputs to identify behavioral trends and failure patterns
Design quality evaluation processes using user feedback such as logs, ratings, and inquiries
Standardize evaluation processes and structure them in a reusable, scalable manner
Automate quality evaluation workflows
Collect and aggregate evaluation data
Establish mechanisms for continuous and recurring quality checks
Build and operate quality feedback loops in collaboration with development, MLOps, and data engineering teams
Document quality issues and risks, and communicate them clearly to relevant teamsMINIMUM QUALIFICATIONS
3+ years experience in QA or testing with products that use LLMs
Experience in test design, including defining test perspectives and creating test cases
Ability to evaluate systems with ambiguous specifications or non-unique “correct” answers by establishing clear judgment criteria
Experience automating test or evaluation processes
Experience collaborating with development teams to drive quality improvements
Business-level proficiency in both English and JapaneseNICE TO HAVES
Experience in scenario testing and red teaming
Experience evaluating and analyzing user feedback and logs
Proactive mindset with the ability to identify problems independently
