Soft Materials Technician Job at Mach Industries (Huntington Beach)

Job Description

As a Soft Materials Technician, you’ll fabricate, seam, assemble, and finish soft material structures that make up our unmanned defense systems. You’ll work with polymers, films, and fabrics, using welding equipment to create vehicles and subassemblies. You’ll support both rapid prototypes (where experimentation and iteration are essential) and production builds (where repeatability and precision drive mission success). You’ll work closely with engineers and fellow technicians to translate designs into reliable, lightweight, high-performance flight hardware.

Job Responsibility

Seam, assemble, and finish soft material components using RF, hot air, impulse, and wedge welding processes
Fabricate vehicles and substructures from polymers, films, laminates, and coated fabrics
Set up, operate, and tune welding equipment to achieve consistent, high-quality welds across varying materials and geometries
Cut and trim welded assemblies to tight dimensional and quality requirements
Conduct in-process inspections of weld quality, seam strength, and dimensional accuracy
identify defects and rework as needed
Support prototype builds: adapting welding methods, experimenting with parameters, iterating with engineers, and documenting lessons learned
Assist with production builds: following controlled work instructions, ensuring repeatability, and meeting takt time
Handle sensitive materials and maintain clean work environments to prevent contamination
Maintain welding equipment, tooling, and fixtures
report wear, calibration issues, and support continuous improvement
Uphold safety, quality, and documentation standards consistent with defense hardware requirements

Requirements

High school diploma or equivalent
1+ years of hands-on experience welding or fabricating soft materials, polymers, or coated fabrics (aerospace, industrial textiles, inflatables, automotive, or similar fields)
Experience operating RF, hot air, impulse, or wedge welding equipment (Miller Weldmaster experience strongly preferred)
Proficiency with hand tools, cutting tools, and basic measuring equipment
Ability to read and interpret engineering drawings and work instructions
Comfortable wearing full PPE and working around heat-based welding equipment
Accustomed to working in a fast-paced, high-expectation environment where quality is mission-critical
Physical capability to lift 25+ lbs, stand and/or sit for long periods, and manipulate large flexible assemblies

Nice to have

Experience fabricating large-area soft structures such as balloons, bladders, inflatables, or flexible tanks
Experience with Miller Weldmaster equipment
Background in prototype or R&D environments where processes are not fully defined
Familiarity with seam testing, leak testing, or destructive/non-destructive evaluation of welded joints
Knowledge of aerospace or defense quality standards and documentation practices
Cross-training in related areas such as composites, coatings, textiles, or mechanical assembly
Experience supporting both development and production manufacturing environments
