Amentum is seeking an experienced Mechanical Engineer with the technical expertise to implement solutions, evaluate products, and build upon an infrastructure that supports the changing needs of our customers. In this role, the Mechanical Engineer will be responsible for preparing and/or maintaining operations documentation, procedures, and methods including user manuals and reference manuals. Provides or coordinates special documentation services as required. Competent to work at a high level of all phases of documentation. May act as project leader. The unique test site we support is perpetually in a state of planning, integration, and test execution. This fast-paced program requires initiative, teamwork, and the ability to effectively communicate across all organizational levels. The team is multi-organizational, and roles span from senior program managers to engineers, to on-site technicians, logistics, budget, and everything in-between. It is, therefore, critical for this role to be able to communicate complex ideas to a broad and occasionally non-technical audience in support of program priorities. The environment demands attention to detail while never losing site of the big picture, in short, execution within the broader strategy.
