How do Tristan Island recruit technicians to submit resumes?

In May this year, Tristan da Cunha, the most remote island in the world, posted a job advertisement in official website, hoping to recruit an auto mechanic for 265 residents on the island with an annual salary of 25,000 US dollars (about 6,543,800 yuan+6,000 yuan). The technician will sign a two-year cooperation contract with the islanders, and will have a six-week holiday every year after joining the company. This is another time for the island to seek talent supply from the outside world after the announcement of recruiting farmers this year 1 month.
