Lead Performance Engineer

 

The opportunity:

We're looking for a Senior QA Engineer to be the technical authority on complex accounts. This is a hands-on technical leadership role—you'll architect automation frameworks, solve the hard problems, and set the technical direction for QA on your engagements, as well as being an active member of the QA community. 

You're the person the team turns to when things get complicated. You've built automation from the ground up, you understand the trade-offs, and you know how to design solutions that scale. You lead through expertise—raising the bar technically and helping others grow through mentorship and demonstration. 

You're also an innovator. You're actively using AI tools to accelerate your work and you're thinking about what's next—whether that's self-healing tests, smarter automation, or new approaches to quality. You don't just follow best practice; you help shape it. 

And beyond the technical, you're a confident communicator who can hold your own with senior client stakeholders—explaining approaches, trade-offs, and recommendations to influence decisions at a project level. 

What you’ll be doing:

• Design, document, and execute test cases across web applications, APIs, and backend systems
• Perform system testing, system integration testing, and exploratory testing
• Build and maintain test automation using Playwright (or similar) with JavaScript/TypeScript
• Integrate automated tests into CI/CD pipelines and contribute to their reliability
• Work in a shift-left approach—participating in refinements, planning, and requirements analysis to catch issues early
• Identify, document, and track defects with clear reproduction steps, collaborating with developers on root cause analysis
• Query and analyse data from various sources (databases, logs, monitoring tools) to investigate issues and validate behaviour
• Contribute to process improvements, and ways of working within your scrum team
• Communicate testing progress, risks, and quality metrics to both internal teams and clients
• Participate in client-facing meetings such as demos, triage calls, and release discussions
• Proactively identify opportunities to improve quality, tooling, or processes—and act on them
