IT Systems Engineer; Robert Half Technology is seeking an IT Systems Engineer for a contract to full-time opportunity. This position requires a Department of Defense (DoD) clearance, so US Citizenship is a must. The IT Systems Engineer position requires the design, configuration, maintenance and repair of our customer's IT infrastructure to support military applications. The position will be part of a team of systems engineers providing technical competency to new and existing systems, delivering mission critical infrastructure across several virtualized computer and network infrastructures and ensuring the highest levels of availability, performance and security through all phases of initial systems design, installation at customer sites and ongoing support of installed systems. This position is expected to provide subject matter expertise for multiple operating system environments, storage area networks and Layer 2/3 switching networks. This position also involves the analysis, design and implementation of network upgrades for all hardware and software components, as well as development of technical documentation in support of system configuration, end-user technical manuals and installation/upgrade instructions. Principle Duties Responsibilities: - Evaluate customer technical requirements and design constraints in support of IT system design and architecture for new or modified environments, including both hardware (server, network and storage) and software. - Provide technical input in support of proposal development to ensure product selection, system design and delivery schedules are properly developed and implemented. - Installation, configuration, maintenance and repair of Active Directory domain environments. - Independent research, selection, best practice implementation and configuration of enterprise software applications, including but not limited to network monitoring, software distribution, intrusion prevention/detection, antivirus, end-point control, software/patch management, email services, file services, print services and database applications. - Installation, configuration and maintenance of storage platforms to include traditional storage area network implementations using fiber-channel and iSCSI protocols, as well as hyper-converged infrastructures within software defined data center architectures. - Installation, configuration and maintenance of multiple operating system environments to include both server and client platforms. - On-site system installation and configuration of new IT systems or modifications to existing systems, and migration from preexisting legacy systems. - Design and implementation of resilient systems design with a primary focus on high availability and fault tolerance, to include disaster recovery scenarios and complete backup and business continuity objectives. - Produce highly consistent technical documentation to include step-by-step configuration procedures, operating instructions in support of end-user technical manuals and installation/migration procedures in support of on-site upgrade efforts. - Comprehend, create and redline technical drawing packages as required for the creation of new IT systems or modifications to existing systems, including assembly, schematic and wire list information. - Design and implement systems level processes for both internal development as well as continued use and operational processes for end-users.
