About The Position

Mach Industries is a rapidly growing defense technology company founded in 2023, focused on next-generation autonomous defense platforms. With approximately 350 employees, it aims to develop scalable, decentralized defense systems and advance manufacturing and national security. The Fabrication Technician supports hands-on prototyping and advanced manufacturing for projects such as custom test-rig builds, structural aircraft modifications, and bespoke R&D hardware. The role requires precision welding, sheet-metal fabrication, machining, and the ability to interpret technical drawings and CAD models. The technician must adapt processes in a fast-moving, iterative environment and collaborate with engineers and technicians across disciplines. Availability for swing shifts is required to support development timelines, with extended hours and weekends as needed.

Requirements

At least 5 years of hands-on fabrication experience in a fast-paced prototyping or production environment.
Proficiency in TIG welding, including aluminum, stainless steel, and carbon steel.
Experience with sheet-metal fabrication, structural assembly, and mechanical integration.
Working knowledge of Flow Waterjet operation.
Ability to interpret technical drawings and follow precise fabrication instructions.
Familiarity with manual machining, including mills, lathes, and grinders, and general metalworking tools.
Strong attention to detail and a safety-minded approach.
Ability to work independently and in cross-functional teams.
Availability to work swing shifts.
Availability to work extended hours and weekends as needed.
Must be a U.S. citizen or national, lawful permanent resident, refugee, or asylee, or eligible to obtain required U.S. Department of State authorizations, to conform to U.S. Government export regulations.

Nice To Haves

Proficiency with CAD software such as Siemens NX or SOLIDWORKS for reviewing and interpreting part models and technical drawings.
Familiarity with machining principles, tolerancing, and GD&T.
Experience collaborating on prototype development, including iterative fabrication and design-for-manufacturing feedback.
Exposure to aerospace, defense, or advanced R&D environments.
Understanding of visual and dimensional inspection and NDT-preparation processes.
Experience with stick welding or dual-shield welding.
Experience with press brake operation and programming.
Experience with fixture and part design.
Woodworking experience.
Comfort working in cross-functional teams alongside engineers and technical leads.

Responsibilities

Fabricate vehicle components, structural assemblies, and custom test fixtures using TIG welding, sheet-metal techniques, and general metalworking.
Perform horizontal, vertical, and overhead welds on aluminum, stainless steel, and carbon steel for prototype and production applications.
Operate Flow Waterjet.
Interpret engineering drawings and technical documents to execute builds accurately and with minimal supervision.
Collaborate with engineers on prototype builds and provide actionable Design for Manufacturing and Assembly (DFMA) feedback.
Assemble structural and fluid systems, including routing and integrating tubes, brackets, and hardware.
Conduct dimensional checks and visual weld inspections, and prepare work for NDT methods such as X-ray and dye penetrant when required.
Apply lean manufacturing practices and contribute to continuous improvement of fabrication processes and workflows.
Maintain and operate manual mills, lathes, and grinders as needed for custom fabrication.
Maintain shop cleanliness, organization, and safety protocols.
