This internship is best suited for someone who has completed or is nearing completion of a two- or four-year technical degree and has practical experience in an assembly, production, or manufacturing environment. You bring mechanical aptitude, experience with hand tools, and curiosity about improving how products are built.

What You Get To Do

• Perform hands-on assembly of components, subassemblies, and systems alongside manufacturing and production teams.
• Fit, adjust, and test hardware to verify proper form, function, and conformance to specifications.
• Troubleshoot assembly and production issues with technicians and operators.
• Support manufacturing improvements by observing processes, gathering data, and helping implement corrective actions.
• Contribute to manufacturing line planning, layouts, and process flow.
• Conduct timing studies to evaluate cycle times and identify improvement opportunities.
• Assist with the design, evaluation, and testing of fixtures and tooling.
• Document assembly procedures, work instructions, and process observations.

What You Bring To The Team

• Completion or near-completion of a two- or four-year technical degree in Mechanical Engineering, Manufacturing Engineering, Industrial Technology, or a related field.
• Hands-on experience in an assembly, production, or manufacturing environment.
• Experience with hand tools, mechanical assembly, or general shop-floor work.
• Ability to apply structured problem-solving to manufacturing challenges.
• Clear written and verbal communication skills.
• Comfort working in an in-person manufacturing environment and collaborating across engineering and production teams.
• Ability to meet the physical requirements of a hands-on manufacturing role, including extended standing, bending, stooping, and lifting.

The hourly rate for this position is $24.00 - $36.00. This range represents the Company’s good faith estimate of the base compensation for this role at the time of posting. Actual compensation will be determined based on several factors, including but not limited to relevant experience, skills, qualifications, internal equity, and geographic location.
