About the role:

The LS-DYNA structural analyst’s role will apply engineering principles to support the design, development, and final verification across a variety of aerospace and defense development programs. The engineer is primarily expected to perform structural analysis using a mix of hand calculations, and finite element analysis (FEA) to support development from the conceptual design phase through to the deployment and operations phase. Primary tasks include building and maintaining finite element models (FEM), authoring stress analysis reports, and supporting test planning. Other common tasks include using FEA to model heat transfer, modelling pyrotechnic & pneumatic gas dynamics, and multi-body kinematics of deployable systems. The analyst will often work independently within a small, fast-moving team. Excellent organization, collaboration, and communication skills are essential parts of the job

 

Responsibilities: 

  •  Applies theories of physics to engineering problems to quantify and predict system performance, support concept of operations (CONOPS) decisions, and support derivation of subsystem requirements.
  • Assesses structural viability of aerostructures, mechanisms, and frangible systems by:
    • Generating free body diagrams, determining load paths, calculating reaction forces and internal loads, and developing shear and moment diagrams
    • Using classic aerospace industry analysis techniques (classical hand calculations, fatigue, and damage tolerance analysis)
    • Build system and component level finite element models.
  • Develop and anchor system and component level loads from finite element models, test data, and engineering standards.
  • Contribute to test plan development and execution by providing technical oversight for measurement of stress, strain, displacement, acceleration, shock, and vibration data during ground and flight tests.
  • Verifies and documents system compliance to requirements.
  • Supports development of engineering reports, presentations, and formal design reviews 

 

Education and Experience:

  • BS, MS, or PhD in Mechanical Engineering, Aerospace Engineering, or equivalent
  • Experience performing structural analysis.
    • Preferably in the aerospace, defense, automotive, or nuclear industries
  • Strong technical knowledge of finite element analysis with experience including:
    • Prediction and validation of frequency dependent structural dynamics and loads
    • Modal, response spectrum and random vibration analysis

Qualifications;

  • This role will be specifically focused on dynamic and static analysis of structures using LS-Dyna; 
    • Must have non-linear analysis experience and LS-Dyna experience.
  • Deep understanding of LS-DYNA including element formulations, material models, contact types and algorithm, and meshing methodologies.
  • Experience with running both the explicit and implicit LS-DYNA solver.
  • Experience analyzing problems that involve ductile failure, strain rate dependency, airbag modeling, impact, drop tests, and/or large deformations.
  • Experience with setting up and post processing analyses using LS Pre/Post.
  • Composite analysis experience
  •  Experience with commercial FEA, meshing, and 3D CAD software tools: FEMAP, NASTRAN, SIMCENTER 3D, Ansys Workbench, Ansys Classic, LS-DYNA, Abaqus, Radioss, SolidWorks, CATIA or similar
  • Experience with common aerospace materials such as high strength aluminum alloys, nickel-based superalloys, titanium alloys, and stainless-steel alloys
  • Experience with computer programming languages such as MATLAB, Octave, Python, VBA, C++, C#, or Julia for automation of analysis tasks such as using a program’s API, plotting result data, or performing coupled trade studies.
  • Strong written and verbal communication, technical report writing skills, organizational and problem-solving skills.
  •  Experience with material testing and material model development for LS-DYNA including failure criterion.
  • Desire and ability to conduct internal LS-Dyna analysis trainings, and act as SME
  • Must be a U.S. citizen and able to obtain a DoD SECRET clearance

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
