Job Title: Mechanical Engineer Job Description

This role focuses on designing and developing mechanical and automated equipment using SolidWorks, with a strong emphasis on OEM, industrial, and machinery applications. You will create detailed designs, documentation, and prototypes, while working hands-on with equipment and collaborating closely with cross-functional teams to solve complex technical problems and support new product and system development.

Responsibilities

• Design mechanical equipment, assemblies, frames, piping layouts, and components using SolidWorks.
• Develop and maintain detailed engineering drawings, bills of materials (BOMs), and manufacturing documentation to support production.
• Design and modify automated process equipment and purification systems to meet performance and reliability requirements.
• Improve and standardize existing equipment designs to enhance quality, scalability, and maintainability.
• Participate in new product and system development from concept through implementation.
• Integrate pumps, valves, motors, variable frequency drives (VFDs), sensors, transmitters, and other instrumentation into mechanical and automated systems.
• Work directly with manufacturing technicians during equipment assembly to ensure designs are practical, buildable, and meet specifications.
• Troubleshoot mechanical issues and support troubleshooting of related electrical and control problems.
• Work with customers, vendors, technicians, and other engineers to identify, analyze, and resolve technical issues.
• Dig into complex problems to determine root causes and implement effective corrective actions.
• Build and prototype systems in a hands-on environment to validate designs and support continuous improvement.
• Take ownership of assigned projects, driving them from concept through design, fabrication, testing, and support.

Essential Skills

• Proficiency in SolidWorks for mechanical design, ideally with experience designing OEM equipment, machinery, or industrial equipment.
• Bachelor’s degree in Mechatronics Engineering, Mechanical Engineering, Electrical Engineering, Electromechanical Engineering, or a related discipline, or equivalent practical experience.
• Experience designing mechanical equipment using SolidWorks in a professional setting.
• Strong mechanical and electrical troubleshooting skills, with the ability to diagnose and resolve equipment issues.
• Hands-on ability to build and prototype systems, not limited to desk-based design work.
• Strong understanding of bills of materials (BOMs) and BOM structure.
• Ability to independently solve technical problems and take ownership of projects from start to finish.
• Comfort working in an ambiguous environment with a self-starter mentality and the ability to learn independently.
• Experience with robotics, robot or machine design, OEM equipment, PLC-related systems, and industrial equipment design.

Additional Skills & Qualifications

• 3–7+ years of experience designing or developing automated equipment.
• Experience programming or troubleshooting PLCs.
• Understanding of industrial automation and control systems.
• Ability to read mechanical drawings, P&IDs, and electrical schematics.
• Experience working with sensors, instrumentation, motors, valves, and other industrial components.
• PLC/HMI experience with platforms such as Allen-Bradley/Rockwell, Siemens, AutomationDirect, or similar systems.
• Experience with VFDs, analog instrumentation, digital I/O, communications, and industrial networking.
• Background with automated machinery, process skids, water treatment, filtration, biotech or pharmaceutical equipment, laboratory equipment, or similar systems.
• Experience taking equipment from concept through design, fabrication, programming, testing, and commissioning.
• Experience working for an OEM, machine builder, or systems integrator.
• Experience developing standardized or configurable equipment platforms.
• Interest in joining a growing startup environment and contributing at an early stage.

Work Environment

This is an onsite role, requiring presence at the facility every day. You will work in a hands-on engineering and manufacturing environment, collaborating closely with technicians and other engineers around real equipment rather than working solely at a desk. The setting involves industrial and automated machinery, including pumps, valves, motors, VFDs, sensors, instrumentation, and PLC-based control systems. You can expect a dynamic, growth-oriented atmosphere where you help build and refine equipment platforms in a startup environment.
