Principal QA Automation Engineer - FinTech - AI

An exciting opportunity has opened for a Principal QA Automation Engineer to join a rapidly growing Payments FinTech. We are looking for a highly technical, hands-on individual contributor who can build and own the automation and quality engineering capability across a complex payments platform. This role is for someone who can go beyond traditional test automation and build automation frameworks, establish meaningful quality metrics, using AI to transform testing and developing and testing AI-powered QA agents.

You will:

• Build the QA automation strategy and technical capability across the payments platform.
• Design and develop scalable automation frameworks for API, integration, contract and end-to-end testing.
• Build automation from the ground up using technologies such as Java/JVM, Golang, REST Assured, Postman/Newman and internal tooling.
• Own the quality and automation metrics across the platform, defining what should be measured and how those metrics are used to improve engineering quality.
• Establish meaningful measures around automation coverage, defect trends, test effectiveness, reliability, flakiness, execution performance and release quality.
• Build automated quality gates and integrate them into CI/CD pipelines.
• Identify opportunities to use AI and LLMs to improve the QA life cycle, from test generation and test analysis through to defect detection and investigation.
• Design, build and test AI-powered QA agents capable of performing testing, analysing results, identifying anomalies and supporting engineering teams.
• Establish approaches for testing AI agents, including accuracy, reliability, robustness, hallucination, regression and behavioural testing.
• Build frameworks and tooling that allow AI-driven testing capabilities to be repeatable, measurable and production-ready.
• Work closely with engineers to improve testability, observability and quality at source.
• Establish engineering standards for automation code, framework design, test data, CI/CD and quality reporting.
• Provide technical leadership through design reviews, code reviews and mentoring, while remaining a hands-on individual contributor.

Key Requirements:

• 7+ years' experience in QA Automation/Quality Engineering, with significant hands-on engineering experience.
• Proven experience testing in Java environment
• Proven ability to build automation frameworks and QA capabilities from scratch.
• Deep experience with API automation, integration testing and contract testing.
• Strong understanding of CI/CD and automated quality engineering.
• Experience with Jenkins, GitHub Actions, GitLab CI or equivalent.
• Experience building, integrating or experimenting with AI agents, LLM-based tooling or agentic workflows.
• Ability to work independently, take ownership and make technical decisions without requiring significant management oversight.
