Basic Qualifications

Experience in one or more Systems Engineering functions, such as:
Experience with requirements and/or system/software modeling, preferred candidate would have both.
US Citizenship required. Ability to obtain final secret clearance

Desired Skills

Clearance: Active secret or above security clearance
Systems engineering experience or relevant systems engineering training through a university or certificate program
Familiarity or proficiency in Cameo Systems Modeler / Cameo Enterprise Architecture or equivalent.

Experience with DOD Software CDRL Development
Ability to thrive in a fast-paced, synergetic team environment.
Demonstrated behaviors of a systems thinker with the ability to select and apply appropriate systems thinking skills to solve problems and implement constructive change.
Excellent written and verbal communication skills, strong social skills, and ability to build consensus among peers while building solid relationships with team members
