Looking for trained and talented Information Technology specialists that possess a diverse knowledge/experience between computer support, systems administration and a dash of network administration. Our team needs experienced professionals already trained with basic skills in all three areas. This is not your typical IT job as you will be working outside of a traditional truncated IT environment. We are looking for individuals that are exceptionally capable and require little supervision while working independently.
