Job Description:

Seeking a software engineer to perform as one of the primary software engineers in the development and integration of cross domain security solutions and other security technologies in a small team environment. These activities are across the development lifecycle from concept development, design, and implementation.  To accomplish these activities candidates will need to apply diverse skills in software engineering, system engineering & administration, integration, test and system security. Customers often come to our unit with a goal in mind, but they need our help to realize it.  As such, candidates should be able to analyze requirements to ensure overall testability, and then develop appropriate software design, test plans, and procedures. Since we are a small team with a small dedicated testing staff, candidates should also be able to assist in the execution of functional, performance, and security tests and support debug of system issues. After developed solutions are deployed, these data flows need to be maintained in operations.  While a separate part of the team does oversee maintenance activities, candidates may be called upon to review existing programs and assist in making refinements to aid in reducing operating time and/or improving current development methods.

As a senior member of the team, the candidate will be expected to help lead the technical direction of the development team.  This includes acting as a technical escalation point and expert reference for the contractor team and government leadership.  Candidates will be responsible for managing the software configuration for the systems and ensuring accuracy of technical documentation.
