Responsibilities

Perform mechanical engineering analysis using ANSYS to support the development and evaluation of new design concepts based on customer requirements, existing drawings, and on-site surveys, acting as either a team member or mechanical lead.
Develop and execute finite element models (FEM) in ANSYS to assess structural integrity, vibration response, thermal behavior, and load paths for assemblies, sub-assemblies, and installed systems.
Use simulation-driven design approaches to validate concepts prior to fabrication, incorporating mock-ups and/or 3D printed parts to correlate physical fit and functional performance with analytical results.
Translate design concepts and requirements into detailed, analysis-informed designs using 3D CAD software, ensuring compatibility with simulation models and manufacturability.
Prepare, review, and evaluate engineering documentation including analysis reports, simulation results, specifications, and test plans, ensuring correlation between analytical predictions and verification methods.
Develop and present analysis-driven briefings for design review milestones (SRR, PDR, CDR), clearly communicating modeling assumptions, results, margins, and risks to stakeholders and customers.
Analyze and evaluate design interfaces, including mechanical, thermal, and dynamic interactions between components and systems.
Develop or support engineering reports such as Weight and Balance Reports, incorporating both calculated data and simulation outputs to assess system impacts from new installations or removals.
Work under general supervision to solve routine to moderately complex engineering problems, leveraging simulation tools and established analytical methods.
Review and approve analysis results, engineering drawings, and technical reports developed by other engineers to ensure technical accuracy and compliance with requirements.
Perform additional engineering and analysis duties as required to support program objectives.
Performs other duties as assigned
