● Ability to work autonomously as the sole QA professional for a product or team. Ability to proactively clarify requirements across teams, even when specifications are ambiguous
● Experience taking ownership of defining quality standards and test strategies, and driving the team to implement them (organization size is not a factor; the role requires building systems/processes rather than simply executing pre-defined tests)
