Quality Engineering
SDET
SDETs who reach CTO think in systems, not scripts—they've debugged entire architectures and understand how quality scales with complexity. This technical depth creates leaders who prevent disasters rather than manage them.
The Career Arc
Rotational · L1–L3
Build the SDET craft. Prove you can wield the tools of Quality Engineering.
Transformational · L4–L7
Deliver SDET outcomes — each Quality Engineering tour at this altitude has a defined mission and success criteria.
- L4 : Lead SDET projects and mentor others
- L5 : Drive test engineering across the org
- L6 : Set test engineering direction
- L7 : Shape the company's test engineering vision
Manage a Team?
Great SDET 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
Foundational · L8–L9
Shape the Quality Engineering organization from the SDET chair — build institutions, not just products.
