The information for Ireland isn't entirely accurate. There's two separate lists for the availability of the Critical Skills Employment permit and the second list requires a minimum annual salary of €60,000[0]:

Occupations with a minimum annual remuneration of €30,000 for a restricted number of strategically important occupations contained in the Highly Skilled Eligible Occupations List. A relevant degree qualification or higher is required.

All occupations with a minimum annual remuneration of over €60,000, other than those on the Ineligible Categories of Employment for Employment Permits or which are contrary to the public interest.

For Sweden, the employment link referenced is for self-employment. The details around regular, full-time employment can be found on Migrationsverket's site[1].
