Applied Multiphysics Engineer III

Amentum Advanced Solutions is a performance unit of our Engineering & Technology (E&T) Line of Business. The Amentum Advanced Solutions specializes in the design, construction, and operation of unique and complex research and development facilities, including, as examples, wind tunnels (aerospace, automotive, and motorsports), rocket test stands, climatic chambers, jet engine test cells, acoustic chambers, altitude test facilities, captive trajectory systems, and nuclear facilities.

Our projects span the automotive, motorsports, defense, nuclear, and aerospace markets. Recent clients include Audi, Boeing, BMW, Ford, Honda, General Motors, NASA, Stellantis, U.S. Air Force, U.S. Navy, U.S. Department of Energy, Volkswagen, and many others in North America, Europe, and Asia.

A mid-level Mechanical Engineer in E&P would perform work on technically challenging and unique design efforts, such as hypersonic wind tunnels, rocket test stands, aerospace test chambers, nuclear facilities, and scientific facilities. The Engineer may function as the Applied Multiphysics lead on small projects, working with other engineers & designer/drafters.

• Independently performs project assignments that involve few complex features and can be guided by codes, standards, and other precedents of the discipline.
• Analyzes and/or evaluates the results of an analysis using techniques prescribed by senior engineers or supervisors.
• Accomplishes, complete tasks of limited scope or solves problems which require investigation of a limited number of variables.
• Prepares technical reports, presentations, and calculations.
• Coordinates the work of designer/drafters or junior engineers.
• May formally reviews 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 structural, mechanical process, controls and instrumentation, and aerodynamics/fluid dynamics engineers.
• Produces complete design packages, including detailed drawings, calculations, and specifications, as required.

• B.S.M.E. from an accredited engineering school
• Minimum of Seven (7) years’ relevant Machine Design experience (see “Adjacent Industries” below)

• Demonstrated knowledge and experience with design of ground test facilities involving extremes in temperature, heat transfer, pressure, and mechanical dynamics.
• Strong mechanical engineering analytical skills – kinematics, dynamics, stress/strain, power transmission, etc.
• FEA – static stress‑strain, natural frequency

• Design for small‑scale fabrication & manufacturing (milling, turning, welding, laser‑cutting, forming, etc.)
• FEA – thermal, non‑linear, forced mode dynamics and multi‑physics analysis, Ansys preferred
• Design experience with ASME B&PV Section VII, Div I & Div II
• Design for assembly & installation
• Demonstrated experience and expertise in employing GD&T/ASTM Y14.5 in detailed design drawings; understanding of tolerance, fits, and stack‑up analysis
• Scope/Schedule/Budget management
• 3D CAD experience, Inventor or Solid Works preferred
• Design for fiber‑composites manufacturing (fiberglass, carbon fiber)
• Fluid Power – employing pneumatic/hydraulic cylinders, valve stand design, P&IDs, etc.
• Basic experience with machine instrumentation (proximity sensors, vision sensors, strain gauges, scales, etc.)
• Installation Support and Supervision – guiding and answering suppliers, sub‑contractors and other trades questions from the office and on‑site

• Aerospace & Defense Mechanical Design
• Machine Design
• Factory Automation (material handling, web handling, process automation, etc.)
• Fluid Power (Hydraulics/Pnumatics)
