Mechanical Analysis Engineer Jobs in Wisconsin (NOW HIRING)

Job Description

Job Title: Sr Mechanical Analyst – Structural and Thermal Analysis!

Job Description

This role provides technical leadership in mechanical analysis for complex electronic systems across a broad portfolio of aerospace, defense, intelligence, cyber, and space programs. You will perform high-quality structural and thermal analyses, guide design optimization, and support both local and remote programs. The position offers the opportunity to work with advanced technologies, collaborate with multidisciplinary teams, and contribute directly to mission-critical systems that support national security and public safety.

Responsibilities

• Provide technical leadership and deliver high-quality mechanical analysis support to locally based programs as well as other programs across the broader electronic systems portfolio, including remote support as needed.
• Plan, coordinate, and execute analysis activities in collaboration with program engineers and program leadership, ensuring alignment with technical requirements, schedules, and program objectives.
• Perform structural analyses using both classical hand-calculation methods and finite element methods to evaluate modal response, random vibration, shock, and static structural performance.
• Perform thermal analyses, including steady-state and transient heat transfer evaluations, to ensure robust thermal performance and compliance with requirements.
• Create detailed finite element models (FEM) at levels ranging from sub-components to full system assemblies using Siemens Simcenter 3D/NX, NASTRAN, Ansys Mechanical, and Ansys Icepak.
• Post-process and interpret finite element analysis results to assess structural and thermal performance, identify risks, and propose design improvements.
• Collaborate closely with mechanical, electrical, optical, and other engineering disciplines to optimize system designs and ensure robust, integrated solutions across the full product portfolio.
• Document analysis methods, assumptions, models, results, and conclusions in clear, professional reports and presentations suitable for internal and external stakeholders.
• Present analysis findings, design recommendations, and risk assessments to internal teams and external customers in a clear and concise manner.
• Mentor and coach less experienced engineers and part-time analysts, providing technical guidance, feedback, and support to help develop their skills.
• Review analysis work products from other team members to ensure technical accuracy, completeness, and adherence to standards and best practices.
• Contribute to a collaborative, inclusive team culture by communicating effectively, maintaining a positive attitude, and supporting cross-functional teamwork.

Essential Skills

• Bachelor’s degree in Mechanical Engineering or Aerospace Engineering.
• At least 4 years of relevant experience in mechanical analysis or a closely related field.
• Proven experience performing modal analyses of structures to evaluate natural frequencies and mode shapes.
• Proven experience performing random vibration analyses to assess structural response under vibratory environments.
• Proven experience performing shock analyses to ensure structural integrity under transient loads.
• Proven experience performing static structural analyses to evaluate stresses, margins of safety, and deflections.
• Experience performing steady-state heat transfer analyses to evaluate temperature distributions and thermal margins.
• Experience performing transient heat transfer analyses to assess time-varying thermal behavior.
• Hands-on experience creating and analyzing finite element models using Siemens Simcenter 3D/NX.
• Hands-on experience using NASTRAN for structural finite element analysis.
• Hands-on experience using Ansys Mechanical for structural analysis.
• Hands-on experience using Ansys Icepak for electronics cooling and thermal analysis.
• Strong understanding of structural analysis principles, including classical methods and finite element methods.
• Strong understanding of thermal analysis principles, including conduction, convection, and radiation heat transfer.
• Clear and effective oral communication skills for technical discussions and presentations.
• Clear and effective written communication skills for documenting methods, results, and conclusions.
• Demonstrated ability to work effectively as part of a team in both on-site and remote collaboration environments.
• Eligibility to obtain a U.S. Department of Defense Secret security clearance.
