Conduct field maintenance and system grooming to ensure optimal performance. Assist with installations and testing as needed.

Ability to work independently with minimal supervision.

Excellent communication skills, with the ability to translate complex IA concepts for various audiences.

Must be a US citizen.

Work Environment & Physical Demands

This role requires a significant commitment to travel and the ability to work in non-traditional office settings. The candidate must be able and willing to meet the following physical requirements:

Securing Your Data

Beware of fake employment opportunities using Leidos’ name.

Further, Leidos will only communicate with you through emails that are generated by the Leidos.com automated system – never from free commercial services (e.g., Gmail, Yahoo, Hotmail) or via WhatsApp, Telegram, etc. If you received an email purporting to be from Leidos that asks for payment-related information or any other personal information (e.g., about you or your previous employer), and you are concerned about its legitimacy, please make us aware immediately by emailing us at [email protected].

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission.
