We are seeking a Senior QA / Software Development Engineer in Test (SDET) with strong engineering capability to support (a) refactoring of existing client facing applications onto strategic components and/or (b) development of a new unified client portal. This is an automation driven engineering role working closely with Java and React engineers in a shared quality model.
Key Responsibilities
• Design and implement automated unit, integration, end to end, and stress tests for both refactored components and new UI functionality, using existing internal frameworks and approved tools (e.g., Playwright, Postman).
• Enhance current automation frameworks where necessary, aligned with established engineering standards.
• Collaborate with backend and frontend engineers to test full workflows across UI, APIs, and microservices.
• Participate in code and test reviews, contributing to testability, best practices, and engineering quality.
• Perform limited exploratory testing early in the cycle until automation coverage is established.
• Ensure automated tests integrate into CI/CD pipelines to support rapid, reliable delivery across both the refactoring programme and greenfield portal build.
• Apply familiarity with Post Trade and Collateral Management lifecycle events (e.g., allocations, confirmations, settlements, margining) to design realistic and business aligned automated tests.
Required Experience
• Bachelor's degree in Computer Science, Engineering, or equivalent.
• 10+ years of combined software engineering and QA automation experience, consistent with seniority expectations across all roles.
• Strong hands-on automation skills using Java or JavaScript/TypeScript, especially with Playwright, Postman, REST/JSON testing, and browser/UI automation.
• Solid understanding of modern web systems (React frontends, REST APIs, microservices) and ability to test full-stack workflows.
• Experience integrating automated tests into CI/CD pipelines.
• Comfortable operating in environments without a separate QA team, where quality is owned collectively.
• Strong debugging, analysis, and communication skills.
• Demonstrated experience testing systems within financial institutions, with exposure to trading, post-trade, collateral, or risk-related platforms in regulated environments.
Nice to Have
• Experience testing cloud-hosted applications (AWS).
• Exposure to Docker/Kubernetes environments.
• Experience with performance or load testing tools.
