Principal Mechanical Engineer, FEA Focus

DRS NPS has an immediate need for a Principal Mechanical Engineer with a focus on design and shock analysis of high-performance rotating equipment and associated static structures. You will provide direct contributor work in designing for mechanical shock survivability and vibration response of large electric motors, generators, and steam turbine assemblies, including foundations.

The ideal candidate is an individual possessing strong mechanical engineering technical skills, a superior knowledge of finite element analysis, and an understanding of the design considerations for large rotating military-grade hardware.

This position is in-office or hybrid based out of DRS's Fitchburg, MA location.

You are expected to work independently or collaboratively as part of an integrated project team, using judgment, experience, and discretion in making complex decisions. You will act as a SME and mentor to more junior colleagues.

You will create detailed design requirements based on customer specifications and design large assemblies to meet those requirements, including material selection and finishes, tolerance analysis, fastener selection, and weld design.

You will execute shock analysis on large assemblies, including:

• Static Analysis
• Transient Dynamic Analysis
• Shock Spectra Response Analysis
• US NAVY dynamic design analysis method, DDAM (T9070-AJ-DPC-120/3010)
• Linear and non-linear contact analysis
• Normal Mode Analysis
• Forces Response Analysis

Critical to success in the role is the ability to breakdown complicated technical challenges and find innovative solutions that meet the program's requirements without adding unnecessary weight or cost. You will need the ability to clearly document and communicate, orally and in writing, to technical and non-technical individuals including project leadership and to other functions including executive management. As part of regular activities, this role will have customer interaction where you will confidently and competently represent DRS in front of customers, including the US Navy.

You will review, analyze, and status project milestones and provide accurate estimates to complete projects or analyses.

You will design for EHS, cost, and manufacturability and demonstrate this skillset in support of manufacturing and field activities.
