Lockheed Martin Rotary & Mission Systems is seeking a Software Developer. In this role, you will perform tasks supporting Navy programs. The successful candidate will be responsible for designing, writing, testing, and integrating defensive security applications and custom configurations into a Red Hat Enterprise Linux (RHEL) platform environment.

This is an active engineering and development role focused on architectural design and system-level mitigation. While the primary focus is on engineering and development, the role involves evaluating third-party software for platform integration compatibility when required. This position is located at a facility that requires special access. The selected candidate will be required to hold an active government Secret security clearance.
