Are you sure? Your link lists 32 jobs. A very large majority explicitly qualify themselves as "senior", "lead", "staff", or "principal" positions. There's also a "director".

There are a handful of postings that don't ask for seniority in the job title (and some are duplicate titles, strongly suggesting that each posting is a single opening). But all of them require at least two years of industry experience. Where are your junior positions? Did you mean to link something else?
