Job Description

Job Description

We are seeking a Mechanical Design Engineer to do cradle to grave work on equipment for mixing, blending, and drying systems.

Looking for an experienced, hands-on engineer who enjoys solving real-world mechanical challenges while working closely with manufacturing, vendors, customers, and engineering teams to develop practical, high-performing equipment solutions.

Job Duties and Responsibilities

· Design custom industrial process equipment and related mechanical systems using 3D modeling software.

· Create detailed assemblies, bills of materials, fabrication drawings, machining prints, and manufacturing documentation.

· Perform engineering calculations related to horsepower sizing, torque requirements, shaft loading, bearing selection, drive system design, motion, heat transfer, and rotating equipment performance.

· Design and support rotating mechanical systems including shafts, bearings, gearboxes, couplings, chain drives, seals, and power transmission equipment.

· Develop manufacturing-ready fabrication and machining drawings including GD&T, fits, tolerances, weldment detailing, and assembly requirements.

· Support redesign, modernization, and reverse engineering efforts for existing or legacy equipment systems.

· Assist in the design and integration of vacuum-rated systems, jacketed vessels, thermal transfer systems, inert gas purging systems, and sealing arrangements where applicable.

· Support equipment selection and configuration based on customer application requirements.

· Collaborate closely with fabrication and assembly teams to ensure practical, manufacturable, and serviceable equipment designs.

Product Testing & Optimization

· Develop and support testing procedures for mixers, mills, blenders, dryers, and related equipment.

· Participate directly in equipment assembly reviews, pilot testing, troubleshooting, and startup support activities.

· Provide hands-on support during fabrication, assembly, equipment testing, and commissioning to identify and resolve mechanical or process-related issues.

· Analyze equipment performance and identify opportunities for improved efficiency, throughput, reliability, manufacturability, and ease of maintenance.

· Recommend and implement design improvements based on testing results, field feedback, manufacturing observations, and equipment performance data to improve reliability, durability, throughput, and serviceability.

· Assist with prototype evaluation, product refinement, and continuous product improvement initiatives.

Qualifications

· Bachelor’s degree in Mechanical Engineering or related field preferred.

· 5–10 years of experience designing heavy industrial machinery, rotating equipment, or custom OEM process equipment preferred.

· Proficiency with 3D CAD software such as SolidWorks or AutoCAD required.
