Dear [Hiring manager's name],
I lead a nine-person QA team, split between manual and automation, for an omnichannel retail platform at Cobblestone Retail Systems, and ten years into QA the question I ask most isn't how many bugs we found, it's how many defects we let become release-blockers in the first place. I'm applying to your QA Manager opening because it's scoped around leading that shift from catching bugs to preventing them.
Introducing a shift-left policy that embeds QA in sprint planning cut release-blocking defects from about 12 a release to 2, and growing automation coverage from 30% to 75% of our regression suite over eighteen months let the team support twice the release frequency without adding headcount. A quarterly quality scorecard I built is now used by engineering leadership to track defect trends across all 6 product teams.
I set test strategy, hire and coach QA engineers across manual and automation disciplines, and manage our test process through Jira and Zephyr. I hold the ISTQB Advanced Level Test Manager certification, and I measure my own success by whether the team needs me less for day-to-day decisions each quarter, not more. I also sit in on a handful of test-plan reviews myself every sprint, since a manager who never looks at the actual test cases loses the details that matter most.
I'd welcome a conversation about the quality challenges [Company name] most needs a QA manager to solve and where ten years of shift-left experience could help. Thank you for your consideration.
Respectfully,
Quinn Thompson
