The freelance Field Engineer platform allows businesses to connect with telecom & IT field engineers from around the world and cooperate on various projects.
The web-based application lets engineers advertise their skills, promote their credentials and search for freelance gigs, but unlike other services, it also allows
them to submit bids, negotiate employment terms and receive payment. Companies in search of talent can fund accounts to manage their field engineering staff budgets,
oversee job progress in real time and perfect the way they evaluate and hire background-cleared bidders.
