- Business impact
- Improves team outcomes, quality and execution.
- Ambiguity
- Moderate.
What good looks like
Senior Quality Engineer consistently demonstrates the expected autonomy and judgment for L3, delivers outcomes appropriate to the scope of the role, applies required Human, Professional and Technical skills at the mapped proficiency, and produces evidence of impact rather than relying on tenure alone.
Typical evidence
Completed work with measurable quality/outcome; stakeholder feedback; examples of problems solved and decisions made; reusable artifacts or improvements; demonstrated skill proficiency; mentoring/influence evidence at senior levels.
Skills expected at L3
Grouped as human, professional and technical. Target proficiency uses the P1–P7 scale, and each row says what that level means for that particular skill.
