The Senior System Administrator (SSA), under the supervision of the SO Manager, works to develop and maintain all of the Professional Service’s Test Labs’ operational systems; this includes all customer test environments, demo environments, shared infrastructure, and the SD Performance Lab.
Serving as the senior member of a small team of system administrators and contributing directly to team productivity, the SSA is responsible for maintaining the integrity and security of SO's Linux, VMware, and Windows servers and systems, as well as two Oracle database servers. The SSA is another capable, available, and independent system administrator for Solutions Operations. The SSA is expected to conduct system analysis to identify potential performance bottlenecks and improvements, and identify and recommend alternative hardware technologies to maximize performance and stability.
The SSA is responsible for emergency response (or coordinating it) as needed to correct system failures.
The SSA must possess extensive experience in UNIX system administration. As new technologies emerge and impact our systems, the SSA is expected to learn these technologies very quickly, develop training of more junior SA staff, and resolve any problems involved in integrating new technologies with our systems.
The SSA is a key technical resource for the SO team, providing advice, training, and technical support for various projects. In addition, the SSA works closely with professional technical staff in the [Tech Ops] System Administration (SA) team and the Performance Test team in evaluating current systems and making decisions on future development.
A primary focus of this position and the offerings it supports is a drive toward profitability through cost efficiency.
