My take on X is a professional job is this: it depends. If you have 20 developers in your team, one or two better be good at UX, one or two better be good at low-level coding, one or two better be good at SEO and so on. If you only have two developers, they better be good at the core product and be mindful of everything else. The third developer is never going to be a tester, QA, or UX if your first two developers can't keep up with the core. In a large pharmaceutical company with 10,000 employees, you have people with job titles like "Quality Assurance Lead II (Wound Management)". In a startup with 3 people, people call themselves CEO, CTO, and CFO. As the startup grows, it will need people. Eventually you'll hire a "QA Lead II" or "UI Editor (Web-Apps Division)". The main question is who do you hire next? Do you need a graphic designer more than a helpdesk person? Do you need a project manager more than an AP assistant?
