I see similar duality in engineers between big corp and start-ups. In big corp, engineers tend to focus on a small part of the system, a small part of the software development cycle. In big corp, engineering could mean a frontend of a customer facing application, uptime of a backend, deployment throughput of something, etc. In start-up, you can be a mix of an idea guy, project manager, frontend, backend, ops, customer support, QA. On the journey to big-corp, start up starts to specialize, cost of communication increased, silos created, customer insight got lost, then the whole cycle repeats (in other start-up).
