About the Role

We are looking for a detail-oriented QA Engineer (Mid to Senior level) to work onsite with our client Plugilo. You will be responsible for ensuring product quality across web, mobile, and API layers

potential risks

• Design and maintain comprehensive test cases, test scenarios, and checklists for functional,

regression, and integration testing

• Execute manual testing across web applications, APIs (Postman/Swagger), and mobile interfaces

• Perform UI/UX testing to validate layout, responsiveness, and cross-browser/cross-device

compatibility

• Track, document, and follow up on bugs using project management tools (Jira, Redmine, or

equivalent)

• Collaborate closely with developers and PM to reproduce issues and verify fixes

• Use AI tools (ChatGPT, Claude, Copilot) to accelerate test case generation, analyze bug patterns,

and draft quality reports

• Support UAT preparation and coordinate with client stakeholders during acceptance testing

phases

• Perform smoke testing and post-release verification after production deployments

• Lead test strategy and define quality gates for release readiness (Senior level)

• Provide regular quality reports including severity distribution, test progress, and release quality

summaries

Required Skills & Experience

Testing Skills (Must-have)

• 3+ years of experience in software QA/testing (Mid) / 5+ years (Senior)

• Strong understanding of software testing methodologies, test levels, and test types (functional,

regression, integration, smoke, UAT)

• Proficiency in writing detailed, reusable test cases from requirements, wireframes, or user stories

• Hands-on experience with API testing using Postman, Swagger, or similar tools

• Basic knowledge of SQL for database verification and data-driven testing

• Experience with bug tracking and project management tools (Jira, Redmine, Trello)

• Understanding of Agile/Scrum development process and QA role within sprint cycles

• Ability to analyze requirements and identify gaps, ambiguities, and potential failure points before

development begins

• Experience testing web applications across multiple browsers and devices

AI-Powered Testing (Must-have)

• Proficient in using AI assistants (ChatGPT, Claude, Copilot) for test case generation from

requirements or user stories or acceptant criterias

• Ability to use AI to review test cases, test suites, test scenarios

• Ability to use AI to analyze bug reports, identify patterns, and suggest root causes

• Experience using AI tools to draft test plans, quality reports, and release notes efficiently

• Understanding of how AI can assist (and where it falls short) in testing workflows — able to

validate AI-generated test cases for completeness and accuracy

Nice-to-have

• Familiarity with automation testing tools (Selenium, Cypress, Playwright) — not required but a

strong plus

• Using AI to generate test script for data testing

• ISTQB Foundation or Advanced Level certification

• Experience with performance testing concepts (JMeter, k6)

• Experience working with international clients (English or Japanese communication)

• Understanding of CI/CD pipelines and how QA integrates into automated deployment workflows

Soft Skills

• Meticulous attention to detail — able to catch subtle UI inconsistencies and edge case bugs

• Clear and structured communication — able to write bug reports that developers can act on

immediately

• Proactive mindset — raises quality concerns early rather than waiting for issues to surface in

production

• English reading/writing proficiency (working with English documentation, test cases, and bug

reports)

• Collaborative team player who can work effectively with developers, PM, and client stakeholders

What We Offer

• Competitive salary with 13th-month bonus (FTE) or premium rate (Freelancer)

• Opportunity to work directly with an international client in a professional environment

• Exposure to AI-assisted testing practices and modern QA workflows

• Career growth path: Mid QA → Senior QA → QA Lead
