It is possible to be a video game tester who primarily works from home. Some game companies, such as Kwalee, seek permanent employees who work remotely, while other companies use freelance job boards or services, such as VMC, Utest and FlexJob, to test their games via temporary remote workers.
Different companies have different policies on how they source game testers and whether they allow them to work from home. Many game companies permanently hire game testers and require them to come in to work at the companies' offices. Other companies use job boards, such as FlexJob, to find freelancers who game test from home. While many job boards feature game-testing work, UTest is one job board that focuses specifically on the software testing industry.
Some game companies do not hire testers or use freelancers at all. Instead, they use outside services to do game testing for them. VMC is one company that specializes in providing remote game testers for video game companies. VMC specifically promotes itself as allowing its employees to work from home.
