Quality Assurance Engineer

The QA Engineer is accountable for overseeing the quality assurance and support activities that are vital to maintaining the stability, security, and overall reliability of GDT’s systems. All accountabilities are executed in alignment with GDT’s technical strategy and GDT’s commitment to operating as an independent, neutral, and transparent price discovery platform.

• Test Planning & Strategy: Define, implement, and manage comprehensive testing strategies for new and existing features, covering functional, regression, performance, and security testing. Work closely with other engineers, product managers, and stakeholders to ensure strategies are agreed, planned, and collaboratively executed, and regularly review and update them to adapt to changing project needs and ensure all critical areas are covered.

• Test Plan Design & Execution: Create comprehensive test plans that set out test strategies, objectives, scope, and resources. Coordinate their execution with other engineers and teams to validate software quality, confirm that all requirements are met, and identify areas for improvement.

• Test Automation: Design, develop, and maintain the automated test framework and scripts using modern test automation tools such as Playwright. Ensure automation efforts align with business objectives, minimising manual testing effort and enhancing platform stability.

• Functional Testing: Perform functional testing to validate that software features operate as expected. Develop, implement, and maintain test plans and test cases for API and end-to-end (E2E) testing, ensuring seamless functionality, data integrity, and adherence to business workflows across integrated systems. Collaborate with product owners and developers so that test coverage meets functional requirements and provides reliable feedback.

• Non-Functional Testing: Conduct non-functional testing, including performance and load testing, to assess the scalability, reliability, and responsiveness of the platform. Work closely with the engineering team to identify bottlenecks and recommend improvements.

• Security in Testing: Integrate security testing into QA processes so that vulnerabilities are identified and mitigated early in the development cycle, and collaborate with the engineering team to prioritise and resolve security issues.

• Issue Triage: Identify, categorise, and prioritise issues to ensure efficient resolution. Work closely with developers and stakeholders to determine the impact of issues and facilitate their timely resolution.

• Live Auction Support: Participate in live auction events as required, ensuring that all functionality is operational and addressing issues in real time. Collaborate closely with cross-functional teams to troubleshoot and resolve problems quickly, ensuring smooth auctions.

• Release Management & Deployment: Assist in release planning and provide a quality assessment to support go/no-go decisions. Ensure smooth transitions from testing to production with minimal downtime or disruption, and validate that deployed features perform as expected in live environments.

• Quality Advocacy & Continuous Improvement: Act as a quality advocate within cross-functional teams, promoting best practice in software development and testing. Review and refine QA processes to increase efficiency and effectiveness, proactively suggest and implement improvements with a focus on automation, security, and efficiency, and stay up to date with emerging technology trends and advances in QA practice.

• Mentoring & Knowledge Sharing: Provide guidance, mentoring, and support to junior QA engineers, promoting knowledge sharing and professional growth. Conduct code and test case reviews to maintain quality standards, and help create documentation, knowledge base articles, and training materials for internal and external stakeholders.

• Cross-Functional Collaboration: Keep the CTO informed of key issues in the quality domain and share insights on emerging industry trends, best practices, and innovative solutions. Work with the Head of Engineering to ensure testing aligns with technical strategy and quality standards; with Product Managers to ensure testing meets user stories and business needs; with Software Engineers to troubleshoot bugs and performance issues; with fellow QA Engineers on coverage, knowledge sharing, and automation goals; and with DevOps Engineers to integrate test automation within the CI/CD pipeline. Provide real-time support to the Trading Operations team on performance and uptime of critical trading platforms, and coordinate with third-party vendors on hardware, software, or external service issues affecting internal systems or customer products.
