Senior AQA Engineer

About Tie

Tie is building the next generation of identity resolution and marketing intelligence. Our platform connects hundreds of millions of consumers across devices, browsers, and channels—without relying on cookies—to power higher deliverability, smarter targeting, and measurable revenue lift for modern marketing teams.

At Tie, AI is not a feature—it is a core execution advantage. We operate large-scale identity graphs, real-time scoring systems, and production ML pipelines that directly impact revenue, deliverability, and customer growth.

The Role

We are looking for detailed-oriented  AQA Engineer. This person is responsible for validating the quality of our software through thorough exploratory, functional, and regression testing. This person is analytical, proactive, and passionate about delivering high-quality user experiences.

Technical Responsibilities

• Review requirements, user stories, and design documents to create detailed and comprehensive test cases and checklists
• Perform functional, integration, UI/UX, and regression testing across web, data, 3d party apps and/or API layers.
• Test on multiple browsers, devices, and screen resolutions to ensure cross-platform consistency
• Execute manual test cases and report issues with clear reproduction steps and severity levels
• Verify fixes and perform retesting and smoke testing
• Maintain test case repositories (e.g., TestRail, Zephyr, Xray, etc.)
• Perform basic API testing using tools like Postman
• Use developer tools (e.g., Chrome DevTools, browser console) to investigate issues
• Track and manage bugs using tools like Jira
• Support release validation in redesign, staging and production environments or any other required.
• Collaborate with developers and product managers to ensure test coverage and align QA efforts with release goals
• Collaborate with business, customer success to ensure the test coverage and align QA efforts with business goals.

Automation & AQA Responsibilities

• Develop and maintain automated test suites for UI and API layers using frameworks like Playwright, Cypress, or Selenium
• Integrate test automation into the CI/CD pipeline to enable fast and reliable deployments
• Prioritize what to automate based on risk, stability, and ROI, complementing manual testing
• Validate data flows and transformation logic in data-driven applications by writing automated assertions against APIs and backend responses
• Build reusable utilities and selectors to support robust and maintainable test scripts
• Work closely with developers to ensure testability and coverage of edge cases
• Use version control (e.g., Git) and test reporting tools (e.g., Allure, TestNG reports) to ensure traceability
• Support debugging and root cause analysis by capturing logs, screenshots, and network traces during test execution
• Maintain a hybrid approach, knowing when to use exploratory/manual testing alongside automation to uncover UI/UX or logic-related issues

Data-Driven Application Testing

• Validate the accuracy, completeness, and integrity of data throughout the user journey
• Perform data validation across frontend, backend, and database layers, including comparing displayed data with source systems or API responses
• Ensure business rules and data logic are correctly applied (e.g., filters, transformations, aggregations)
• Test the impact of edge cases and malformed data inputs on application behavior
• Perform SQL-based verification (or through data exports) to confirm data correctness, where applicable
• Validate data syncing between systems, especially in applications that consume or expose third-party data via APIs
• Monitor how updates to records, entries, or data states reflect across the application (e.g., state transitions, user-based data visibility)

Non-Technical Responsibilities

• Participate in daily stand-ups, sprint planning, and retrospectives to represent QA priorities
• Communicate bugs and quality concerns clearly to cross-functional teams
• Proactively raise red flags if requirements are unclear, incomplete, or inconsistent
• Help define and improve QA processes, checklists, and acceptance criteria
• Collaborate with product and design teams to ensure test scenarios reflect user expectations
• Own the quality mindset for the features being delivered
• Provide feedback on usability and suggest improvements from a user perspective
• Maintain a clear audit trail of testing progress and coverage
• Be a champion for documentation, keeping test plans and QA procedures up to date
• Collaborate with QA Team Lead in providing feedbacks and reviews of QA strategies, processes, practices.

Working in Ambiguous and Fast-Paced Environments

• Confidently test features with minimal or evolving specifications, using exploratory testing and product intuition to uncover edge cases
• Collaborate closely with developers, product managers, and other stakeholders to clarify intent and co-create acceptance criteria when missing
• Document findings, gaps, and assumptions clearly to reduce miscommunication and improve team alignment
• Adapt quickly to frequent changes in priorities or scope, while ensuring quality is not compromised
• Use structured approaches to test loosely defined features, such as session-based test charters or heuristic checklists

• Maintain composure and clear prioritization even during high-pressure releases, rollbacks, or urgent hotfixes
