A "Contract Engineer" is a professional engineer who is hired on a contractual basis rather than as a permanent employee. Contract engineers are typically brought on board for specific projects or periods to provide specialized skills and expertise. They can work in various fields, including civil, mechanical, electrical, software, and more. These engineers often have flexible work arrangements and may handle multiple contracts with different employers simultaneously.
