&gt;a UI&#x2F;UX engineer who can develop large-scale apps with an eye towards security, performance, reusability, and maintainability.<p>I&#x27;ve never head this referred to as a UI&#x2F;UX engineer. You seem to have just described a web developer. If you&#x27;re developing &quot;large-scale apps&quot; then you&#x27;re definitely doing more than UI&#x2F;UX, so why call it UI&#x2F;UX engineering?
