Description Why Sabel Systems Sabel Systems designs and delivers digital engineering ecosystems for DoD programs, enabling teams to connect data, systems, and personnel within secure, scalable environments. Our solutions empower programs to make faster decisions, close sustainment gaps, and meet the digital acquisition requirements. Rather than simply proposing transformation, we implement and operate it  method is clear: we orchestrate existing tools into a governing system of record, ensuring government ownership of infrastructure and traceable decisions.

There's no vendor lock, no proprietary baselines, and no need for ATO rebuilds during transitions. Sabel Systems is redefining modern defense acquisition. If you seek to solve complex challenges at scale and want your work to directly accelerate military capability while reshaping the DoD's approach to digital engineering, this is the place for you. Complexity Simplified. Mission Amplified. What You'll Do
* Design and develop high-fidelity simulation models using ANSYS STK, ANSYS engineering software, Aer Sim, and other advanced COTS modeling tools; translate customer mission requirements and system constraints into comprehensive, executable simulation architectures
