Overview
Company
Impact
Profile match
Fuku is a recruitment business operating in Singapore and Malaysia that advertises client vacancies under its own name across a wide range of industries. The roles it posts span software engineering, accounting, sales, customer service, logistics, hospitality and administration, offered on permanent, contract and gig terms, which is characteristic of an agency working for many employers rather than hiring for itself. It runs a high-volume careers board with several hundred open positions at a time, and the listings carry the agency as the employer of record rather than the company the candidate would actually join.
