Job summary

Pentangle Tech Services | P5 Group seeks a structural engineer to lead design, analysis, and validation of heavy mechanical structures. You will create 3D models, perform FEA, and ensure designs meet strength, durability, and manufacturability standards.

You will collaborate with manufacturing, testing, and suppliers to deliver production-ready solutions, review drawings, and drive design verification throughout the lifecycle.

Qualifications

• Bachelor’s degree in mechanical, structural, or related engineering.
• Typically 5+ years of relevant experience for a mid/senior-level role.
• Proficiency with Creo/SolidWorks and FEA tools (Creo Simulate, ANSYS, or Nastran).
• Knowledge of GD&T, tolerances, materials, welding, and fabrication.
• Understanding of static and dynamic structural analysis.
• Experience with structural testing and validation.

Responsibilities

• Develop structural designs and 3D models for frames, brackets, chassis, enclosures, platforms, and other mechanical structures using Creo/SolidWorks.
• Perform structural calculations and FEA to evaluate stress, deformation, fatigue, buckling, and factor of safety under various loading conditions.
• Prepare and review engineering drawings, GD&T, tolerances, material specifications, and design documentation.
• Perform load calculations and structural analysis considering static, dynamic, impact, vibration, and operating conditions.
• Collaborate with manufacturing, testing, electrical, hydraulics, suppliers, and project engineering teams to develop production-ready designs.
• Conduct design reviews, root-cause analysis, and corrective actions for structural failures, quality issues, and field problems.
• Support prototype development, testing, validation, and design verification and incorporate test results into product improvements.
• Optimize designs for weight, cost, strength, durability, manufacturability, and assembly while following engineering standards.
• Work with suppliers and manufacturing teams to resolve fabrication, welding, machining, casting, and sheet-metal-related issues.
• Maintain engineering documentation, BOMs, design changes, and ECN/ECR activities throughout the product development lifecycle.
