Software Developer ( R-00080087 )


AI Developer



Chantilly, Virginia, United States


Job Description:

Leidos is looking for a Software Developer to support a mission focused project in the Chantilly, VA area. This position requires an active TS/SCI Polygraph in order to be considered.

The successful candidate will join a high profile, fast-moving team of full-stack developers utilizing Java and JavaScript in a fluid agile environment catering to demanding stakeholders and highly visible applications. The team works with mobile applications and utilizes the strict security environment.

The select candidate will support a high profile program on a project that produces highly visible products for senior leadership. The individual will be responsible for activities associated with development, upgrades, maintenance, research and development and testing. Duties will relate to new and existing applications, features, web services, and major enhancements to include supporting in the areas of creation, coordination, dissemination, security and conveyance.

The environment demands focus, concentration, as well as patience and versatility to take part in all that is required to get mission accomplished, including O&M and R&D on top of existing development duties. While processes are in place, due to requirements and needs moving and changing quickly, this advanced and tightly run team, demands fast and fluid structures. Individuals must work as efficiently within the unit as they would on their own without extensive direction. The right individual will be open, responsive and pro-active (take ownership) when there is limited documentation. The resource will need to seek out needed information and understand all impacts to ensure successful execution. A key attribute will be professionalism and clarity in communicating with stakeholders, multiple and different layers of management, as much as with the technical team.
