The Role

We’re looking for a hands-on Mechanical Engineer to lead equipment improvements, reliability upgrades, and system enhancements across our fleet and operations.

This role is ideal for an engineer who enjoys working on real equipment, not just designs on a screen — someone who likes finding failure points, improving uptime, and taking projects from concept through field implementation.

You’ll play a key role in improving the performance, reliability, and serviceability of existing systems while supporting the development of upgrade packages for legacy equipment.

What You’ll Work On

Continuous Improvement & Engineering Upgrades

• Assess existing mechanical and electrical systems to identify inefficiencies, bottlenecks, and failure points.

• Design and implement mechanical improvements, component upgrades, and system enhancements.

• Lead reliability-focused redesigns to reduce failure rates and improve equipment uptime.

• Develop and implement upgrade packages for legacy equipment.

Technical Design & Analysis

• Create or update CAD models, engineering drawings, and technical documentation.

• Perform engineering calculations, FEA, tolerance analysis, or other relevant mechanical assessments.

• Evaluate new materials, components, or technologies suitable for system improvements.

• Collaborate with electrical engineers on integrated electromechanical solutions.

Project Execution

• Drive improvement projects from concept through commissioning.

• Work hands-on with equipment during prototyping, installation, and validation.

• Coordinate with suppliers, fabricators, and internal teams to execute modifications.

• Develop testing procedures and performance verification.

Support & Troubleshooting

• Provide engineering support for field issues and assist with root-cause analysis.

• Train technicians on new designs, modifications, and procedures.

• Participate in reliability reviews, hazard analyses, and maintenance planning.

What We’re Looking For

• Degree in Mechanical Engineering or equivalent technical discipline (or extensive relevant experience).

• Proven experience in equipment design, system improvement, industrial machinery, or similar environments.

• Strong understanding of mechanical systems, rotating equipment, hydraulics/pneumatics, or power systems.

• Ability to interpret and produce detailed engineering drawings and CAD models.

• Hands-on, practical approach to problem-solving with the ability to work on equipment directly.

What Will Set You Apart

• Experience with electrical systems or electromechanical integration.

• Background in continuous improvement methodologies (Lean, Six Sigma, RCA, FMEA, etc.).

• Familiarity with manufacturing processes or fabrication methods.

• Strong troubleshooting and diagnostic skills.

• Clear communicator who documents work and shares knowledge effectively

Compensation & Benefits

• Employer-paid medical insurance for employee and family

• Employer-paid group life insurance

• 401(k) with 4% company match

• Employee-paid dental, vision, short-term , and long-term

• Voluntary life, accident, illness, and hospital coverage
