Log on to Microsoft's corporate career website located in the resources section of this article. Since Xbox Live is directly a part of the Microsoft Corporation, this is the first place to start looking for open positions.
Enter search keywords to locate a job with the Xbox Live enforcement team. Some keywords to start with are, "Enforcement," "Xbox LiveE" and "Policy." To narrow your search, you can select specific job categories. Two good categories to begin your search in are "Legal & Corporate Affairs" and "Operations."
Click on a position that interests you from the populated list. Once you have reviewed the job responsibilities and qualifications, click on "Apply to job" and follow the prompts.
Check the Microsoft Careers website regularly. Some positions are only open for applications during a short period of time.
