CAS/COTS Systems Integration Engineer - Senior

Primary Mission

• Integrate, configure, implement, troubleshoot, maintain, and support CAS (Commercially Available Software) and COTS (Commercial Off The Shelf) software and hardware within RHEL-based development, integration, and operational environments.
• The engineer serves as a technical integrator rather than solely as a Linux administrator. They need to understand how operating systems, applications, hardware, displays, networking, storage, virtualization, security controls, and automation interact and be capable of isolating problems that cross those boundaries.

Core Responsibilities

• The engineer will install, configure, upgrade, integrate, and troubleshoot COTS software and associated hardware; implement and maintain RHEL environments; support workstation/thin-client architectures involving GNOME, RDP, headless displays, and virtualized monitors; perform kernel and package updates; manage local DNF repositories; develop Bash scripts and Ansible automation; use Git for configuration management; diagnose system performance and latency; and work within SELinux/FIPS environments.
• The engineer will also troubleshoot issues involving physical servers, workstations, displays and peripherals, KVMs, networking equipment, storage systems, virtualization platforms, operating systems, and applications.
• The position supports both development/integration environments and deployed operational systems.
• The engineer may have partial technical ownership of COTS implementations but is not expected to independently own every component of the complete architecture. They will work with other engineering disciplines, customers, and vendors to resolve integration issues.
• Documentation is important, particularly configuration records, implementation procedures, troubleshooting findings, changes, automation, and operational knowledge. Formal engineering drawings are not a primary responsibility.
