• Analyzes and/or evaluates the results of an analysis using techniques prescribed by senior engineers or supervisors.
• Accomplishes, complete tasks of well-defined scope or solves problems which require investigation of a limited and well-defined number of variables.
• Prepares technical reports, presentations, and calculations.
• Coordinates with designer/drafters.
• May formally review the work of others for techniques and technical approach, if in area of specific technical expertise.
• Supports interface development with other disciplines, working closely with machine design, structural, mechanical process, controls and instrumentation, and aerodynamics/fluid dynamics engineers.
• Participates in the production of complete design packages, including detailed drawings, calculations, and specifications, as required.

Minimum Experience/Education:

• B.S.M.E. from an accredited engineering school
• Minimum of Three (3) years' relevant Mechanical Engineering experience (see "Adjacent Industries" below)
