Job description

(#4423)

Position Overview: 

We are looking for a Senior AQA Engineer with strong hands-on automation experience and deep expertise in quality engineering practices. The ideal candidate will own the quality assurance execution for the platform, manage test processes end-to-end, and work closely with engineering and product teams to ensure high-quality, compliant, and reliable software delivery.

Our client is a global UK-based financial services and investment banking organization developing an AI-powered document processing and automation platform used across multiple business units. The platform handles large-scale data ingestion, classification, quality validation, and workflow orchestration, requiring strong testing discipline and robust automation practices.


Responsibilities:

  • Develop and maintain comprehensive quality strategies, test plans, and test approaches to support continuous delivery.

  • Lead and manage the full test lifecycle, including planning, estimations, governance, risk mitigation, and defect management.

  • Design, build, and maintain automated test suites (smoke, regression, API, integration) using modern frameworks and tools.

  • Execute automated tests, analyze results, troubleshoot failures, and provide meaningful quality metrics to stakeholders.

  • Collaborate closely with developers, architects, product owners, and automation specialists in an Agile environment.

  • Advocate for quality-first engineering practices, ensuring that quality is embedded into every stage of the SDLC.

  • Ensure compliance with testing standards, internal policies, and regulatory requirements.

  • Identify improvement opportunities in testing processes, tooling, and internal control frameworks.


Requirements:

  • Extensive experience across all stages of the software development lifecycle, including system, integration, regression, and acceptance testing.

  • 6+ years of hands-on test automation experience, particularly designing automation frameworks.

  • Strong knowledge and practical experience with API test automation using tools such as RestAssured, SOAPUI, Postman, or similar.

  • Experience implementing automated tests within CI/CD pipelines, including pipeline configuration and test integration.

  • Strong understanding of Agile practices, including TDD, BDD, user story testing, and continuous integration workflows.

  • Proficiency with SQL/PL/SQL for backend data validation and query-based testing.

  • Ability to clearly articulate technical issues, test results, and quality risks to engineering teams and management stakeholders.

  • Strong problem-solving skills with the ability to identify control weaknesses and propose improvements.

  • Experience working in complex enterprise or regulated environments (financial services is a plus).


Nice to Have:

  • Experience testing AI/ML systems, document processing pipelines, or data-heavy workflows.

  • Knowledge of performance testing tools (JMeter, Gatling) or security testing practices.

  • Experience with Google Cloud tooling or distributed microservices environments.

  • Familiarity with test reporting frameworks, quality dashboards, or analytics tools.
