Job

The Leonardo DRS Naval Power Systems business is a trusted provider of innovative naval gas and hybrid power systems, control technology and support solutions for the U.S. Navy and navies around the world.

As a Senior Mechanical Engineer – FEA & Shock, you will serve as a technical expert responsible for the structural dynamics, shock survivability, and vibration performance of mission‑critical equipment. You will work alongside multidisciplinary engineering teams to design, analyze, test, and qualify products that meet stringent military standards while supporting programs from concept through production.

In this role, you will work as part of an integrated project team, using judgment and discretion in making complex decisions. We are looking for an SME and mentor to more junior colleagues and those who are eager to learn more about shock and vibration design.

You will execute shock analysis on large assemblies, including:

• Static Analysis
• Transient Dynamic 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 break down 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, technical and programmatic information to technical and non‑technical individuals including the team, 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 safety and manufacturability and demonstrate this skillset in support of manufacturing and field activities.

• Expert knowledge of MIL‑S‑901D IC2, MIL‑DTL‑901, familiarity with shock and vibration testing and experience working with various shock and vibration testing facilities.
• Expert experience with the ANSYS Mechanical (Workbench) finite element analysis (FEA) software.
• Demonstrated excellence applying fundamentals of mechanical design, including material selection.
• Proven experience individually driving the product development cycle from concept to qualified/fielded systems.
• Experience with system‑level thinking and system engineering principles/methods.
• Experience with the design and analysis of large welded fabrications and complex rotating assemblies.

• Experience with the development of rotating machinery and associated manufacturing drawings.
• Familiarity with the full manufacturing process including casting, forging, welding, machining, and factory assembly best practices.
• Experience with ANSYS ADPL (ANSYS Classic).
• Proficient with Computer Aided Design (CAD) Tools (Siemens NX and/or Solidworks preferred).
• Experience with MSC family of analysis and pre/post software: NASTRAN / PATRAN / APEX.
• Experience with various available shock and vibration analysis supporting programs: UERD, SIMPLE, etc.
• Experience with Program Management tools (MS Project preferred) and/or agile Project Management tools- (Jira preferred).
• Experience with execution of projects for the US military.
• Active security clearance.

You’ll be part of a collaborative engineering organization developing technologies that support the safety and effectiveness of the U.S. Navy. We offer challenging technical work, opportunities for…
