Sound Design Internship Jobs (NOW HIRING)

SUMMARY: The Manufacturing Intern at Hercules Industries will play a hands-on role in improving how products are designed and built. This is not a passive, observational internship; interns will work directly with engineering and production teams to support product design enhancements, analyze manufacturing processes, and identify automation opportunities. This role is ideal for someone who enjoys both design and shop floor problem-solving and wants to see how engineering decisions translate into real-world production outcomes. M-F 7am-3:30pm, $23.00/hour

Timing & Commitment:
This is a Summer 2026 internship running from mid-May through August (approximately 10–12 weeks). The expected start date is flexible between May 15 and June 1, depending on academic schedules. Some flexibility in start and end dates may be accommodated.

ESSENTIAL DUTIES AND RESPONSIBILITIES include the following. Other duties may be assigned.

Product Design & CAD Support

Create and modify 2D and 3D models of HVAC components (ductwork, fittings, assemblies) using tools such as AutoCAD, SolidWorks, or Inventor

Ensure designs align with SMACNA standards and internal specifications

Support design updates to improve manufacturability, cost, and performance

Manufacturing Process Improvement

Partner with production teams to understand fabrication processes (cutting, bending, forming)

Identify opportunities to improve efficiency, reduce waste, and streamline workflows

Support implementation of process improvements on the shop floor

Time Studies & Process Analysis
