Being a Principal QA Engineer at Box UK

Quality isn’t a checkpoint at Box UK – it’s woven into everything we build. As a Principal QA Engineer, you’ll be a driving force behind that culture: raising the bar on how quality is defined, practised, and continuously evolved across our client projects and internal engineering team.

You’ll own quality end-to-end on complex, multi-technology projects while actively shaping the practices, standards, and automation capabilities that the wider QA function relies on.

In this role you will…

Lead quality on client projects

Take ownership of quality strategy from discovery through to delivery
Collaborate in requirements analysis to shape testable acceptance criteria from the outset
Define test approaches and coverage strategies appropriate to project risk, complexity, and timeline
Be responsible for quality throughout the full development lifecycle, not just test execution

Drive continuous improvement

Identify systemic quality gaps and champion initiatives to address them
Analyse and share quality metrics to surface trends, measure improvement, and inform decisions
Contribute to and help evolve Box UK’s QA standards, processes, and tooling

Build and maintain robust test capability

Design, write, and maintain high-quality manual and automated tests in line with Box UK’s guidelines
Set up and scale automation frameworks (e.g. Playwright, Robot Framework) to support teams effectively
Ensure test suites remain reliable, maintainable, and genuinely useful – not just present
Support and mentor QA engineers, sharing knowledge and raising capability across the function

Be an active team member

Attend and contribute meaningfully to project, team, and client meetings
Provide clear, timely feedback to project teams through regular and ad-hoc reporting
Work closely with developers, product managers, and designers to embed quality thinking early
Provide timely estimates for QA effort in relation to existing projects and new opportunities.

For this role the following skills are essential…

Communication and collaboration

You can articulate quality risk clearly to both technical and non-technical audiences, build trust quickly, collaborate effectively, and influence without authority.

Continuous improvement mindset

You don’t just flag problems; you diagnose root causes, propose solutions, and follow through on making things better.

Technical depth

You bring genuine hands-on expertise in test design and automation, not just familiarity.

Problem solver

You relish complex challenges and approach them with creativity and pragmatism.

Self-directed

You manage your own workload effectively, prioritise well under pressure, and know when to escalate.

Resilient & tenacious

You maintain high standards and composure even when timelines are tight or requirements shift.

Meticulous

You catch what others miss and bring that same thoroughness to documentation, defect reports, and test coverage.

And you will also need…

5+ years of relevant QA experience, with demonstrable seniority in at least some of that time
Proven experience leading QA on projects end-to-end within agile delivery teams
Strong practical knowledge of test design techniques and when to apply them
Hands-on experience setting up, designing, and maintaining automation frameworks – Playwright preferred
Solid experience testing RESTful APIs and diagnosing integration issues
Experience testing across web and mobile applications
Proficiency with Git/GitHub and standard version control workflows
Experience with defect management processes and diagnostic/debugging tools
ISEB Intermediate, Certified Agile Tester, or equivalent
Familiarity with Jira, Confluence, and test management tooling

And in return…

You will enjoy a competitive salary and a comprehensive benefits package.

We recognise that our success comes from the talent, passion and dedication of our team. Working collaboratively, we share the challenges and rewards that come from growing our company, reinforcing our culture of ownership. We understand the importance of personal growth and professional development and invest in the skills of our people to nurture their talent. Our working environment is fast paced, exciting and fun to work in.

We are an inclusive employer that welcomes diversity, challenges discrimination and promotes equality. We welcome and encourage applications from people of all backgrounds and do not discriminate on the basis of any protected characteristic.

Ready to Join Us?

If you’re passionate about embedding quality into every stage of the software lifecycle, enjoy setting standards for complex, multi-technology projects, and want to help drive a culture where excellence is the default, we’d love to hear from you.
