Senior GUI Software Engineer – X Windows/Motif, SL-GMS, Fortran

Agile Decision Sciences is seeking a Front End GUI Engineer to support the RSCCE system for the CECOM Army Software Innovation Center at Aberdeen Proving Ground. RSCCE is a long-lived, mission-critical system built on legacy Digital Equipment Corporation (DEC) VAX/OpenVMS platforms, with operator displays developed in the Sherrill-Lubinski Graphical Modeling System (SL-GMS) on DECwindows Motif, OpenVMS’s integrated X Window/Motif environment, and application code in Fortran 77.

You will sustain, troubleshoot and enhance the system’s graphical operator interface, working alongside the RSCCE Cyber Engineer and Database Engineer. This is a rare opportunity for an engineer who enjoys bridging legacy and modern technology on a system that directly supports strategic satellite communications.

• Work directly with system users and operators to capture requirements and translate them into software and display design changes.
• Analyze, test, troubleshoot, patch, update and install software on the RSCCE baseline.
• Resolve application errors and software bugs; identify root causes and recommend mitigation or resolution actions.
