Core Responsibilities

Primary Functions

Designing, developing, and meticulously executing comprehensive, well-structured test plans and test cases that cover all aspects of software functionality, from front-end user interfaces to back-end APIs.
Identifying, recording, and thoroughly documenting software defects and bugs within a tracking system like Jira or Azure DevOps, ensuring each report is clear, concise, and easily reproducible for the development team.
Conducting thorough regression testing when bugs are resolved or new features are introduced to verify that fixes do not negatively impact existing, stable functionality.
Performing detailed functional and non-functional testing, including but not limited to UI/UX testing, API testing, performance testing, security vulnerability checks, and compatibility testing across different browsers, devices, and operating systems.
Collaborating closely with cross-functional agile teams, including product managers and software developers, to understand requirements, define acceptance criteria, and ensure quality is a primary consideration from the earliest stages of development.
Analyzing user stories and technical requirements to create detailed, comprehensive, and well-structured testing strategies and estimates for planned work.
Executing manual test cases with a high degree of precision and an inquisitive mindset, exploring edge cases and unconventional user flows that automated scripts might miss.
Developing and maintaining automated test scripts for regression and smoke testing using established frameworks such as Selenium, Cypress, Playwright, or Appium to increase efficiency and test coverage.
Setting up and managing test environments, including configuring software, deploying builds, and preparing realistic test data to simulate real-world usage scenarios.
Performing API-level testing using tools like Postman or SoapUI to validate data integrity, server responses, and the correct functioning of microservices.
Investigating and debugging issues to identify the root cause, often working alongside developers to trace problems through code and logs.
Creating and presenting clear, concise test summary reports that provide stakeholders with a comprehensive overview of testing progress, quality status, and risk assessment.
Participating in and providing constructive feedback during design and specification reviews, advocating for testability and a quality-first approach.
Validating that the final product meets all business requirements and adheres to established quality standards before each release.
Staying current with new testing tools, technologies, and industry best practices to continuously improve the team's testing processes and strategies.
Performing exploratory testing to discover defects and usability issues that were not anticipated in the formal test planning process.
Verifying the integrity and accuracy of data as it moves through the system, including database validation and ETL process testing where applicable.
Conducting load and stress tests using tools like JMeter or Gatling to ensure the application is scalable, stable, and can handle expected user traffic.
Ensuring that the application complies with accessibility standards (e.g., WCAG) and provides an inclusive experience for all users.
Reviewing and analyzing system specifications to provide timely and meaningful feedback, identifying potential gaps or ambiguities before development begins.

Secondary Functions

Mentoring and providing guidance to junior members of the Quality Assurance team, fostering a culture of continuous learning and excellence.
Contributing to the continuous improvement of the organization's QA processes, methodologies, and tools to enhance overall efficiency and effectiveness.
Collaborating with customer support and technical account management teams to triage, reproduce, and validate customer-reported issues.
Actively participating in all agile ceremonies, including sprint planning, daily stand-ups, sprint reviews, and retrospectives, to represent the quality perspective.
