Job Responsibilities

Join a team of smart and motivated professionals. As a Quality Assurance Engineer (Manual & Automation), you will have broad leeway to analyze problems, propose and implement solutions, and bring new ideas to life. You will participate in all activities pertaining to the end-to-end testing process: requirements analysis, test design and execution, and the design, development and ongoing maintenance of an in-house Selenium/Playwright-based framework of automated tests. Automated testing is used to validate our client’s proprietary software applications used by both our client and our customers. You will work closely with other testers, developers, and subject matter experts to prepare and automate test plans, track automation result data, while aligning results with executive strategy. This is a hybrid role: you will leverage our AI-powered QA workflow plugin throughout the entire process.

We are seeking a Senior QA Engineer who will serve as a technical leader and subject matter expert in both manual testing and test automation, with strong experience in Selenium/Playwright and C#, strong SQL/database skills, and the ability to work effectively with AI tools to deliver quality at speed. This role does not involve people management, but we are looking for someone who can mentor others, lead technically, and independently drive automation strategy and execution.

The ideal candidate is passionate about delivering high-quality software through robust automated testing and enjoys working in a technically challenging environment with complex applications and data models.

Major responsibilities include:

Analyze requirements and design, create, and execute manual test cases (functional, regression, exploratory) using the team’s AI-powered QA workflow plugin.

Evaluate which test cases to automate and generate, review, and maintain automated tests using the plugin, applying your technical judgment to validate and refine AI-generated output.

Log defects and report manual and automated test results in Azure DevOps.

Provide skilled input for planning, scheduling, and implementation of test automation projects and component level architecture within the automation framework.

Design and implementation of scalable, maintainable, and high-quality test automation scripts (AI-assisted) to expand on our automated regression test set.

Act as the go-to expert on Selenium/Playwright-based test automation in C#.

Participate in defining automation test objectives, strategies, standards, and metrics.

Analyze complex relational databases to retrieve, validate, and prepare test data using advanced SQL, including reading and leveraging stored procedures.

Write and optimize complex queries for data validation and troubleshooting.

Conduct code reviews, mentor mid/junior testers, and help elevate the overall technical quality of the test automation team.

Contribute to test planning and risk analysis discussions from a technical standpoint.

Track, report, and communicate test results and automation progress to stakeholders.

Debug and improve upon existing automated tests and automation framework.

Communicate with cross-functional areas impacted by automation.

Interact with developers and other business unit members to help identify, analyze, and resolve issues.

Work independently and with a team with minimal supervision.

Use AI-assisted tools, including our QA workflow plugin, as a core part of daily work to accelerate test design, execution, and automation.
