Senior/Lead QA Engineer

Architus specialises in connecting leading UK and US businesses with top EU engineering talent, helping build high-performing technology teams and establish presence overseas. With offices in London and Vilnius, Architus has a strong track-record and impressive list of clients such as Invesco, Tide, Capital Group, Schroders, BNP Paribas, and HSBC.

The Opportunity

We are partnering with a leading global digital investor communications platform that provides Proxy Voting and Shareholder Disclosure services to financial institutions worldwide. Originally developed within a major financial institution, the platform is transforming capital markets through innovative, secure, and compliant technology solutions.

We are looking for an experienced Senior / Lead QA Engineer to own quality across complex software delivery projects and play a key role in ensuring the quality, stability, and reliability of a mission-critical financial platform.

This is a hands-on role suited to someone who thrives in fast-paced delivery environments, has exceptional attention to detail, and enjoys working closely with Product, Operations, and Engineering teams.You will take ownership of end-to-end quality across complex releases, shape requirements from a testability perspective, define test strategies, validate business-critical workflows, challenge the effectiveness of automated testing, and help drive continuous improvements to QA practices.

In this model the QA Engineer is a peer of the Software Engineer and the Product Manager, not a downstream tester. They shape the specification so that it can be tested, set the test strategy, challenge whether the automated tests prove the requirements, and give the final testing sign-off before release.

Key Responsibilities

• Lead the overall quality approach across new feature development, enhancements, and platform releases, combining manual, exploratory, API, and automated testing.
• Analyse business and functional requirements, user stories, and technical specifications to create comprehensive test scenarios and test cases.
• Lead testability discussions during requirements refinement, ensuring acceptance criteria are clear, measurable, and testable.
• Execute functional, regression, integration, system, and user acceptance testing.
• Validate complex workflows, data processing, and business-critical financial transactions.
• Define risk-based testing strategies and determine the appropriate level of verification for each feature.
• Identify, document, reproduce, and track defects using JIRA and other defect management tools.
• Perform detailed regression testing ahead of major deployments and releases.
• Participate actively in Agile ceremonies including sprint planning, daily stand-ups, and retrospectives.
• Provide clear and consistent reporting on testing progress, risks, and release readiness.
• Assist with release documentation, user manuals, and client-facing release notes.
• Drive continuous improvements to QA processes, testing standards, and AI-assisted delivery practices.
• Mentor QA engineers, provide technical guidance, and help establish high testing standards across the team.
• Review automated tests critically to ensure they provide meaningful coverage and accurately validate business requirements before release.

Requirements

• Strong experience as a Senior QA Engineer, Senior Test Analyst, or Test Lead, owning the testing approach for complex projects or workstreams.
• Excellent understanding of software testing methodologies, risk-based testing, and QA best practices.
• Experience defining test strategies, leading risk-based testing, and making release readiness or testing sign-off decisions.
• Experience reviewing requirements for testability, facilitating requirement discussions (e.g. Three Amigos), and defining comprehensive test strategies.
• Experience building and maintaining automated regression and API test suites using tools such as Postman, Selenium, Playwright, or Katalon.
• Ability to read and review automated test code and validate test coverage.
• Ability to critically evaluate automated tests, identify gaps in coverage, and challenge whether the tests truly validate business requirements.
• Experience working with CI/CD pipelines, Agile delivery environments, and making evidence-based release recommendations.
• Experience using Jira, Azure DevOps, or similar test management and defect tracking tools.
• Experience documenting business processes or system functionality for both technical and non-technical audiences.
• Experience within regulated or enterprise-scale environments is a plus.
• Experience with AI-assisted software delivery, reviewing AI-generated tests, or testing AI-enabled features would be a strong advantage.
• ISTQB Advanced certification.
