Mechanical Engineering Internship

Job Type & Pay

• Job Type: Part/Full-time, 30-40 hours per week, primarily on-site with occasional hybrid flexibility
• Base Pay: $20-25 per hour commensurate with experience

Zolo Carbon Smartech is a global technology company delivering real-time combustion insight to energy‑intensive industries such as steel, refining, petrochemicals, and power generation. Our laser-based monitoring systems operate in demanding industrial environments, turning previously invisible combustion conditions into actionable intelligence that improves safety, efficiency, reliability, and environmental performance.

We build long‑lifecycle, mission‑critical systems deployed worldwide. Our work sits at the intersection of hardware, software, and real‑world industrial operations, and we value engineers who are thoughtful, collaborative, and disciplined in how they build and maintain reliable systems.

We are seeking a Mechanical Engineering Intern to join our Engineering & Technology team. In this role, you will contribute to the design and testing of mechanical components and systems that support Zolo's combustion monitoring platforms. This is a unique opportunity to gain practical industry experience and contribute to real‑world solutions.

You will work closely with other engineers and cross‑functional teams to implement and support mechanical designs that interface with electronics, instrumentation, and deployed systems. The focus of this role is supporting manufacturing, service, and ongoing product improvements.

This position is well suited for mechanical engineers interested in systems‑oriented development and hardware‑adjacent mechanisms, working primarily from an office with occasional hybrid flexibility.

• Mechanical designs supporting laser‑based combustion monitoring systems used in industrial applications
• Mechanical components that interface with sensors, instruments, and hardware subsystems
• Iterative improvements informed by testing, service feedback, and product priorities

• Core Engineering Responsibilities
• Design and test reliable mechanical components and systems, following established design practices.
• Implement mechanical design features and enhancements based on defined requirements and design guidance.
  
  Contribute to documentation and testing to support long‑term maintainability.

• Systems & Cross‑Functional Collaboration
• Work closely with hardware/software engineers, systems integration, service, and production teams to support integrated solutions.
• Assist with hardware–software integration and internal validation efforts.

• Engineering Practices & Growth
• Write clear and well‑documented design documentation.
• Follow established design development standards and contribute to continuous improvement of tools and practices.
• Grow technical skills through collaboration with more experienced engineers and exposure to real‑world systems.

• Required
• Currently pursuing a degree in Mechanical Engineering or a related field (at least 3rd year undergraduate or recent graduate).
• Proficiency in 3D CAD Solid Works.
• Interest in manufacturing, product design, and process improvement.
• Previous experience with fiber optics (desirable).
• Strong problem‑solving skills and attention to detail.
• Ability to work independently on assigned tasks while collaborating effectively with a team.
• Clear written and verbal communication skills.

This role is based in Louisville, CO
.

Travel is not expected and would be limited to rare, planned occasions if needed.

• Flexible hybrid work arrangements
• Opportunity to work on meaningful industrial technology used in real‑world operations
• Collaborative, supportive engineering culture
• Professional development and growth opportunities
