Senior Quality Automation Engineer ／SDET（Software Development Engineer in Test）

700万円〜1,200万円

東京都

■Recruitment Background
VISASQ operates a global knowledge platform connecting businesses with expertise across 190+ countries and a network of over 800,000 experts. Our Global Expert Network Service (ENS) provides high-precision matching for professional clients, including consulting firms and financial institutions.

As we accelerate the development of autonomous AI agents and expand across Web, Mobile, API/Backend, and AI/LLM surfaces, product complexity and release frequency are scaling rapidly. To maintain high quality standards without slowing development velocity, we are moving beyond traditional QA toward a modern, engineering-driven quality architecture.

Addressing non-deterministic AI/LLM outputs and microservice consistency requires embedding quality early in the development lifecycle ("Shift-Left") and building automated testing pipelines. We are seeking a Senior QA Engineer (SET) to drive our test automation architecture, establish quality gates, and foster a culture of quality ownership across our global engineering organization.

■Responsibilities
Lead our quality engineering strategy across Web, Mobile, API/Backend, and AI/LLM features—from architecture design of test automation frameworks to CI/CD pipeline integration.

Cross-Platform Test Strategy: Define test plans across Web (Frontend), Mobile (iOS/Android), API/Backend microservices, and AI/ML features while leading "Shift-Left" practices from the design phase to identify defects early.

Test Automation Architecture: Architect, build, and maintain scalable test automation frameworks (Playwright, Cypress, Appium, REST, etc.), optimizing execution speed and eliminating test flakiness.

CI/CD Quality Gates: Integrate automated test suites into CI/CD pipelines (Azure Pipelines, GitHub Actions, CircleCI, etc.) to automate release verification and support high-frequency deployments.

AI/LLM Quality Evaluation: Establish methodologies and automated metrics for evaluating LLM outputs, including regression testing for prompt updates, edge-case validation, and safety assessments.

Exploratory Testing & Triage: Perform advanced exploratory testing to uncover subtle edge cases, drive root-cause analysis, and streamline defect prioritization with engineering teams.

Technical Leadership: Track and visualize quality metrics (coverage, defect rates, escaped bugs) and partner with engineering leadership to embed quality standards across teams.

■Technical Environment
[ENS Development Common Stack]
Programming Languages: C#, Python, TypeScript
Backend Frameworks: ASP.NET Core, FastAPI
Frontend Framework: Angular
Infrastructure: Microsoft Azure
Databases: SQL Server, Cosmos DB
Communication: Slack, Google Meet, Jira
Documentation: Azure Wiki, Confluence
AI Tools: Claude Code, Devin, Gemini

[QA Specific Tools]
Web E2E Automation: Playwright, Cypress
API Testing: Postman, REST-assured, or code-based API testing tools
CI/CD: Azure Pipelines
Primary Development Languages: TypeScript, C#

■Highlights of the Role
Global Cross-Cultural Team: Work primarily in English alongside cross-cultural engineering teams based in Tokyo and EMEA.

Architectural Impact: Take full ownership of shaping our test automation foundation, CI/CD integration, and quality governance rather than simply executing test cases.

Cutting-Edge AI/LLM Testing: Gain rare hands-on experience defining evaluation frameworks and automated regression testing for non-deterministic generative AI features.
