Senior QA Engineer (Manual & Automation)

Flat Rock Technology is a technology-driven organisation focused on building robust, scalable software solutions for clients worldwide. We value quality, pragmatic problem-solving, and continuous improvement, creating an environment where QA engineers have a real voice in how products are built and released.

We are looking for a Senior QA Engineer with strong experience in both manual and automated testing across web, API, and mobile applications. You’ll own testing strategy, build and maintain automation suites, and help teams ship with confidence. Experience using AI tools in your testing workflow is a strong plus. We’re committed to supporting professional growth through training and relevant certifications, including ISTQB, and we welcome engineers eager to expand into AI-assisted testing and testing of AI-powered products.

What You’ll Do:

• Develop and execute test plans, test cases, and strategies based on project requirements, risks, and business priorities.
• Perform functional, integration, regression, end-to-end, and exploratory testing across web, API, and mobile applications.
• Design, build, and maintain automated UI and API test suites using Playwright, Cypress, or Selenium, integrated into CI/CD pipelines.
• Plan and run performance and load tests, analyse results, find bottlenecks, and recommend improvements.
• Use AI tools and coding assistants to speed up test generation, automation, and analysis, while validating AI-generated output.
• Identify, document, track, and verify defects, with clear reporting through to resolution.
• Run smoke, regression, and basic security testing to assess release readiness.
• Work with developers, DevOps, Product Managers, and stakeholders throughout the Agile lifecycle, communicating progress, risks, and recommendations.

What You’ll Bring:

• 5+ years of QA experience covering both manual and automated testing.
• Strong knowledge of QA methodologies, test design techniques, defect management, and Agile/Scrum.
• Hands-on experience with Playwright, Cypress, or Selenium using JavaScript/TypeScript, Python, or Java.
• Solid API testing experience (REST/GraphQL, Postman or similar) and an understanding of unit and integration testing.
• Practical performance and load testing experience with k6, JMeter, Gatling, or similar.
• Experience using AI tools and coding assistants (e.g. Claude Code, Cursor, GitHub Copilot, ChatGPT) in testing, with the judgement to review and validate generated tests.
• Familiarity with CI/CD pipelines, Git, Docker, and SQL.
• Experience with Jira and test management tools such as TestRail or Qase.
• Strong analytical, problem-solving, documentation, and communication skills, with excellent English.
• Ability to show examples of automation frameworks, performance tests, and AI-assisted testing from previous projects (e.g. a repo or walkthrough during the interview).
• A degree in Computer Science, IT, Engineering, or a related field, or equivalent practical experience.

Nice to Have:

• ISTQB certification.
• Experience testing AI/LLM-powered applications, including prompt evaluation, output quality, and safety mechanisms.
• Mobile testing and automation with Appium, Espresso, XCUITest, BrowserStack, or Sauce Labs.
• Knowledge of security testing principles and tools such as OWASP ZAP or Burp Suite.

We offer:

• Competitive salaries based on performance reviews with additional benefits;
• Opportunities for professional growth and career development;
• Supportive environment with mentoring from senior engineers;
• Challenging work in a fast-growing international organization;
• Opportunity to work on real-world, production systems;
