Senior Test & Integration Engineer

Mach Industries•Huntington Beach, CA

2d•$160,000 - $200,000

About The Position

Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 220 employees, we operate with startup agility and ambition. Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security. We’re looking for a Senior Test Integration Engineer to own electrical interconnect systems across our UAV platforms. This is a highly hands-on role focused on designing, building, and validating harnesses that operate in demanding environments. You’ll work across electrical, mechanical, and test teams to deliver reliable, lightweight, and production-ready harness solutions, while also contributing to test infrastructure like fixtures and system test racks. This role requires speed, autonomy, and a strong bias toward execution.

Requirements

5+ years of hands-on experience designing and building wiring harnesses or electrical interconnect systems
Deep understanding of connectors, shielding, grounding, and cable design for real-world environments
Strong ability to read and create schematics, wiring diagrams, and harness documentation.
Proven experience taking hardware from prototype through production
Comfortable working with standard electrical test equipment (DMMs, oscilloscopes, continuity/hipot testers)
Demonstrated ability to move fast, iterate quickly, and solve problems with minimal direction

Nice To Haves

Experience with UAVs, aerospace systems, robotics, or other high-performance hardware
Familiarity with EMI/EMC best practices and high-reliability design
Experience with harness CAD tools (SolidWorks Electrical, CATIA, Zuken, Altium, etc.)
Background in designing or supporting test fixtures, breakout systems, or test racks
Hands-on experience working with contract manufacturers or in-house production teams

Responsibilities

Own end-to-end design of UAV wiring harnesses: concept → prototype → production.
Design for power, high-speed signals, RF, and mixed-signal systems under tight size, weight, and power constraints
Rapidly iterate on harness layouts, routing, and packaging with mechanical and electrical teams
Full harness design including connectors, shielding strategies, wire types, and protection schemes for harsh environments (vibration, temperature, EMI)
Drive design decisions with a focus on reliability, manufacturability, and field serviceability
Lead bring-up and integration of harnesses into full vehicle systems
Define and execute validation: continuity, insulation resistance, shielding effectiveness, and system-level functional checks.
Identify and fix issues quickly during integration and flight test cycles
Work directly with technicians and vendors to transition harnesses from prototype to production
Define build processes, QA checks, and acceptance criteria
Troubleshoot production issues (opens/shorts, intermittent faults, connector failures, shielding gaps)
Continuously improve harness designs based on production and field feedback
Own root-cause analysis of electrical interconnect failures in lab, production, and field
Use oscilloscopes, DMMs, hipot testers, and other tools to diagnose complex issues
Drive corrective actions quickly and prevent recurrence
Create and maintain harness drawings, pinouts, and build docs
Keep documentation lightweight, accurate, and usable by technicians
Maintain revision control without slowing down development speed
