Yes, in most cases, you require a visa to look for jobs abroad if you plan on staying in the country for an extended period. A tourist visa permits short stays but does not allow the visa holder to look for jobs or take up employment during their stay. While a majority of work visas require a valid job offer as one of the requirements, there are, however, countries that offer job seeker visas. A job seeker visa allows individuals to enter the country without an employment offer, stay there for a specific period, and look for jobs, provided they meet the eligibility requirements.
