Senior SDET

Senior QA Engineer role at a world leading technology organisation operating across 27 countries.

Key quality advocate within a high performing Agile team, with a shift left, API first and automation focused approach.

Hybrid working, Belfast based. Salary up to £65,000.

About the Company:

Our client is a world leading technology organisation operating at significant global scale, with 60 offices, 27 countries and over 5,300 people. Their engineering teams build and maintain business critical systems that process enormous volumes of data and transactions daily, and they take the quality of that engineering seriously. Self organising, cross functional Agile teams, a genuine focus on continuous improvement and knowledge sharing, and a culture where engineers are trusted to influence outcomes rather than simply execute. Quality is not an afterthought here. It is built in from the start.

Why Work Here?

This is a company that is genuinely investing in Belfast. They have hired 12 engineers here already this year, not as a cost saving exercise, but because they are building serious engineering capability in Northern Ireland for the long term. To support that growth, they have just moved into a brand new office in Belfast city centre, purpose built to house the expanding team and give engineers the environment they need to do their best work. The Belfast team is not a satellite office doing maintenance work. It is a core part of a global engineering organisation tackling complex, large scale problems with modern technology and real autonomy.

If you are a senior QA engineer who wants to work at the intersection of world class technology and global financial markets, where quality is not optional and the systems you test have to perform under significant pressure, this is worth exploring. The problems are hard, the scale is real, and the opportunity to lead and mentor within a high calibre team is genuine.

Key Responsibilities:

• Lead test strategy across the Agile team, balancing manual, automated and performance testing approaches with a strong shift left and API first emphasis.
• Design, develop, execute and maintain automated and functional tests within CI and CD pipelines.
• Build and maintain scalable, self healing automation frameworks using Playwright or similar tooling.
• Leverage AI tools such as Copilot, ChatGPT and Amazon Q to optimise testing efficiency and automation workflows.
• Collaborate with global BA, Development and QA teams to design and coordinate effective test strategies.
• Champion quality across the Agile team, promoting best practices including unit testing and code reviews.
• Identify performance bottlenecks and provide actionable recommendations.
• Mentor and coach team members to elevate QA standards across the engineering function.
• Take ownership of deliverables, managing priorities effectively and raising risks early.

What You'll Need:

Essential:

• Extensive experience in QA automation within Agile environments.
• Strong automation experience using tools such as Selenium, Cypress, Playwright or TestComplete.
• Proficiency in Java, JavaScript or similar programming and scripting languages.
• Proven ability to design and maintain scalable automation frameworks, ideally with Playwright or WebDriverIO.
• Experience integrating automation within CI and CD pipelines using Jenkins, GitLab, TeamCity or similar.
• Hands on experience with BDD frameworks such as Cucumber.
• Experience using AI tools to design and optimise test automation.
• Strong experience in API, functional and end to end testing.
• Experience defining acceptance criteria and aligning testing to business requirements.
• Working knowledge of non functional testing including performance, load and stress testing with tools such as K6 or JMeter.
• Experience working in Agile or SAFe environments with distributed teams.
• Strong communication, stakeholder engagement and problem solving skills.

Nice to Have:

• Experience with AWS, microservices and serverless architectures.
• Formal testing qualifications such as ISTQB or Agile Testing certification.
• Exposure to TDD and BDD design approaches.

Why Apply?

• Salary up to £65,000.
• Hybrid working with a Belfast base.
• Part of a rapidly growing Belfast engineering hub, with 12 new hires already this year.
• Senior QA scope with real authority over test strategy, automation standards and quality culture.
• AI assisted testing is a genuine expectation here, not a nice to have.
• Mentoring remit to grow the QA capability of the engineers around you.
• Self organising, cross functional Agile teams with direct access to Principal Engineers and Architects.
• Long term investment from an organisation committed to building world class engineering in Belfast.
