About Mach Industries

Founded in 2023, 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 350 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.

The Role

As Lead Manufacturing Engineer, Test, you will be the technical owner of production testing across all products and subsystems. This scope includes PCB flashing and configuration, component and subassembly test, end-of-line (EOL) system functional test, and final acceptance. You will define what gets tested, where, and how. You will design, source, and launch the stations, fixtures, software, and data flows that make it work at rate. You will work across Product Engineering, Firmware, Manufacturing Engineering, Controls, Quality, Supply Chain, and Operations so that design intent becomes repeatable, high-coverage, data-rich production testing.

This is a hands-on technical role with direct reports. You will set the technical direction for your test area and guide the engineers, technicians, and integrators working on it. You will also be on the floor bringing up stations, debugging failures, and keeping hardware moving.

Key Responsibilities

Own production test strategy and execution for assigned products and subsystems, from incoming and component test through subassembly test, EOL functional test, rework and retest, and final acceptance.
Turn product requirements, design intent, and DFMEA/PFMEA risks into test requirements, coverage maps, test limits, and pass/fail criteria.
Author and own the Design for Test (DFT) section of the Manufacturing Engineering DFM/A Guide. Write guidelines for test access and test points, programming and debug access, connector and harness access, built-in self-test and diagnostics, calibration provisions, and serialization and traceability. Keep the section current as products and test methods change, and use it in design reviews so Product Engineering designs for testability from the start.
Own the PCB flashing strategy. Decide where in the build flow boards and modules get programmed (at the supplier, at board-level test, or at system integration). Select programming methods and equipment, such as JTAG/SWD, bootloader over USB, CAN, or serial, and gang programmers, based on cycle time, cost, and rate.
Develop and launch production flashing stations and processes. Partner with Firmware Engineering to release production firmware images under configuration control. Own image versioning, checksum and readback verification, unit-specific configuration (serial numbers, calibration data, and keys or secure provisioning), and re-flash processes for engineering changes and rework.
Develop, validate, and launch production test stations and fixtures, such as:
Avionics and PCBA functional test
Wire harness continuity and hipot test
Leak and pressure decay test profiles for fuel, pneumatic, and sealed assemblies
Turbojet engine acceptance testing
RF, datalink, and GPS checkout
Sensor and IMU calibration
Control surface and actuator verification
Full-system EOL functional test
Design or specify test fixtures and interfaces in 3D CAD. Develop or review test station electrical schematics and integrator designs.
Write equipment and process specifications, assess vendor and integrator capabilities, and make data-driven sourcing and make-vs-buy recommendations.
Lead vendors and integrators through design reviews, Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), installation, and commissioning.
Validate test systems before release using MSA/Gage R&R, golden-unit and limit-sample correlation, and guardband analysis.
