About The Position
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.

The engineer will sustain, troubleshoot, and enhance the system’s graphical operator interface, working alongside the RSCCE Cyber Engineer and Database Engineer. The role supports a system that directly supports strategic satellite communications and involves both legacy-system maintenance and analysis and planning for modernization or migration. Work is onsite at Aberdeen Proving Ground, Maryland, in a secure Government lab. Occasional CONUS travel may be required. The employee must be able to work in an environment handling classified information and follow all AT/INFOSEC/OPSEC requirements. Active DoW Secret clearance or higher is required; candidates without at least Secret clearance will not be considered.
