Manage a Team?
Great Performance managers are practitioners first. The Quality Engineering IC responsibilities in L4–L7 are your foundation — your management responsibilities are additive:
- • Hire QEs who think like users—not just testers who find bugs
- • Coach your team to advocate for quality, not just report defects
- • Run 1:1s that build automation skills and product intuition
- • Give feedback that elevates testing from gatekeeper to quality partner
- • Remove blockers—fight for test environments, time in the release cycle, and respect
