That broader effort is known as Joint All-Domain Command and Control (JADC2). As envisioned, JADC2 will allow U.S. forces from all services - as well as allies and partners - to sense, make sense and act upon a vast array of data and information faster than adversaries can detect and respond to.

    • Python script development 
    • Elasticsearch / Logstash / Kibana 
    • Linux systems administration 
    • Windows systems administration 
  • Demonstrated ability to influence development of solutions that impact strategic project/program goals and business results; and to recommend and develop new technical solutions, products, and/or standards in support of program strategy and operations.  
  • Experience with managing technical staff on IPTs and/or cross functional teams to enable significant positive impact on project results/outputs. 
  • Strong written and verbal communications, team building and collaboration skills.  

Preferred Qualifications  

  • Prior experience working on ABMS or JADC2 initiatives, or other US Air Force Customer programs   
  • SD-WAN knowledge and experience 
  • Ability to obtain a TS/SCI clearance  
  • Software Engineering experience, e.g., with creation, authoring, execution and documentation of test cases/result sets for software products in an agile cadence 
  • Experience working/testing within Commercial Cloud Platforms (ex: AWS) and DevOps tools 

At Leidos, we don't want someone who "fits the mold"-we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, what's next? before the dust settles on what's now.
