A great QA engineer is one of the most valuable people on any delivery team — and at Kainjoo, you’ll prove that. You’ll be the last line of defence before things go live, and the person who keeps quality standards high across every project. You’ll work across SaaS platforms, dashboards, and web builds, and you’ll bring structure and rigour to every release.
You’ll define test plans, execute them thoroughly, and work closely with developers to get issues resolved fast. You’ll also join client UAT sessions and help triage real-world feedback into clear, actionable bug reports.
