Responsibilities

Plan, conceptualize, and create mechanical and structural designs for new and existing products using 3D CAD software

Develop complete drawing packages including layouts, detailed part drawings, assemblies, and installation instructions with proper GD&T, weld symbols (AWS D14.1/D1.1), and dimensional tolerancing

Personally detail and draft your own mechanical parts and large structural weldments (e.g., enclosed box sections, columns, frames), ensuring designs are production-ready and aligned with fabrication processes such as machining, forming, casting, forging, and welding

Engineer and size mechanical and structural connections, including bolts, pins, and welds

Determine appropriate fastener sizes, bolt patterns, and weld configurations based on load requirements, strength, and fatigue analysis

Design and size rotating components such as gearboxes, shafts, motors, brakes, wheels, shivs, and drums

Perform system-level calculations (e.g., torque, horsepower, load) and collaborate with vendors to select and integrate optimal components

Select and size bearings using industry standards and life calculations (e.g., L10 life) to ensure durability and performance of hoist and rotating applications

Perform and review structural analysis using hand calculations and/or FEA

Validate designs for stress, fatigue, strength, and compliance with applicable codes

Design large-scale enclosures (e.g., containers, operator cabs) with internal bracing, structural integrity, and integration with mechanical systems

Provide technical guidance to junior engineers and drafters

Check and review engineering drawings and calculations for accuracy, clarity, and analytical support

Work closely with cross-functional engineering teams, vendors, and contractors to ensure successful system integration

Participate in design reviews, generate technical reports/specifications, and communicate updates with the Chief Engineer

Ensure compliance in all safety, health, and environmental regulations, policies, and procedures for a goal of zero incidents and injuries

Communicate consistently on all activities to appropriate individuals (both internal and external)
