Project Summary: Our Linux Systems Administrator/Engineer would support a variety of projects ranging from private cloud to custom digital signal processing (DSP) equipment. The private cloud focuses on dynamic deployment applications for a developer-based user community, automation of network services (Cisco and HP products), and SR-IOV/PCI-pass-through designs for deterministic processing requirements within a virtual environment. Support to the DSP projects involves interfacing the analog world to the digital Linux system through Software Defined Radios (SDR). The projects are responsible for extending the use of SDRs within the customer environment, ensuring that changes necessary to fulfill new requirements can be made in software and not require additional hardware (and associated procurement lead times).
