In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.

This position will require a pre-employment background check and a pre-employment drug test.

Candidates for positions requiring a security clearance are required to be tested for the absence of any illegal drug as defined in 10 CFR 707.4 prior to an offer of employment being made. In addition, once employed, employees will become part of a random drug testing program and may also be tested in the event of any incident causing injury or causing damage to property, or if it is determined that there is a reasonable suspicion the employee is under the influence of drugs or alcohol. This position will require preemployment background check on the part of the Company and in order to receive a Q security clearance, a background investigation by the Federal government. Subsequent Federal government reinvestigations may be required.
