Senior QA Engineer
Project description
The project is a strategic initiative to deliver a new FX Swaps clearing capability, enabling atomic processing of swap packages (two-leg forwards) within a highly regulated, low-latency clearing environment. The QA Engineer will contribute across the full testing lifecycle, including functional, integration, performance, and non-functional validation, while supporting continuous delivery in an agile environment. This is a mission-critical backend system, operating under strict latency (≤10 seconds SLA), resilience, and regulatory (EMIR) constraints, with a strong emphasis on automation-first testing and AI-assisted engineering practices. The solution will initially be deployed on-prem, with planned migration to AWS.
Responsibilities
- Design, develop, and execute comprehensive test strategies and test plans covering functional and non-functional requirements Develop and execute automated test cases using: Cucumber / Gherkin, ORQA, existing java-based testing frameworks Build and extend automated tests, while collaborating with Java Automation Engineers responsible for enhancing and maintaining core test frameworks Validate end-to-end FX swap processing, ensuring atomic transaction integrity Perform integration testing with external venues (e.g., FX matching platforms) Perform testing of MQ-based integrations and XML messaging (ClearLink APIs) Actively use GitHub Copilot and approved AI tooling for: test case generation, scenario expansion, coverage optimisation Contribute to AI-driven testing improvements, including: intelligent test design, potential AI agents (e.g., validation, quality checks) Conduct performance, latency, and capacity testing to meet strict SLA requirements (≤10 seconds) Validate resilience, failover, and disaster recovery scenarios Collaborate with developers, DevOps, and Product Owner to ensure quality throughout the SDLC Support OAT (Operational Acceptance Testing) and UAT phases Analyse defects, perform root cause analysis, and ensure timely resolution Contribute to test automation coverage and CI/CD pipeline integration Ensure high automation coverage (automation-first approach; manual testing only by exception) Produce test reports, metrics, and documentation aligned with LSEG standards Participate in agile ceremonies and support incremental delivery across release cycles Provide go-live and post-release support, including weekend releases where required
SKILLS
Must have
- Strong experience in QA engineering (10+ years preferred) Proven expertise in test automation frameworks (Cucumber, Selenium or similar) Experience testing Java/Spring Boot-based applications Strong knowledge of functional, integration, and regression testing Experience with API testing and integration testing Solid understanding of non-functional testing (performance, resilience, capacity) Familiarity with test management, defect tracking, and reporting tools Experience working in Agile/Scrum environments Strong understanding of SDLC and QA best practices Ability to validate complex workflows and transaction-based systems Strong focus on test design, coverage, and automation strategy (not only execution) Comfortable working in an environment where AI-assisted development and testing is standard practice
Nice to have
Experience in financial services, trading, or clearing platforms Exposure to low-latency testing and SLA-driven systems Experience with performance testing tools (e.g., JMeter, Gatling) Familiarity with Oracle databases and backend data validation Experience with test environments involving caching layers (HazelCast) Exposure to DevOps pipelines and CI/CD test integration Understanding of regulatory and compliance testing (EMIR, financial controls) Experience validating high-resilience / mission-critical platforms Exposure to AI-assisted testing or test optimisation techniques
