Senior 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 QA Engineer to 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 testing activities across complex releases, validate business-critical workflows, identify defects early in the development lifecycle, and help drive continuous improvements to QA processes and release quality. 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 manual and automation testing activities across new feature development, enhancements, and platform releases.

Analyse business and functional requirements, user stories, and technical specifications to create comprehensive test scenarios and test cases.

Execute functional, regression, integration, system, and user acceptance testing.

Validate complex workflows, data processing, and business-critical financial transactions.

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.

Support QA process improvements and contribute to establishing best practices across the team.

Mentor junior QA team members and promote high testing standards.
