A job title can describe the level of the job or the responsibilities of the position. For example: Vice President, Director or Manager. Other job titles reflect what the person does in the job. For example: iOS Game Programmer, VFX Artist or Level Designer. If your current job title is not the norm for your Industry than adjust it for your LinkedIn profile. For example, if internally you are called a Software Engineer III, but to the outside world you are really managing a team, use words like Team Lead or Manager. These titles are more descriptive of your true job function.
