Job summary

Mach Industries in Huntington Beach, CA, is seeking a Lead Manufacturing Engineer, Test to own production testing across all products and subsystems. This includes PCB flashing, end-of-line testing, and data-flow design.

You will design, source, and launch stations, fixtures, software, and data flows, working with Firmware, Manufacturing, Controls, Quality, Supply Chain, and Operations to ensure repeatable, high-coverage test processes.

Qualifications

• Bachelor's degree in Electrical, Mechanical, Aerospace, Computer, or Manufacturing Engineering.
• 7+ years of experience in manufacturing test, test engineering, or production validation in aerospace, automotive, electronics, or comparable complex hardware environment.
• Demonstrated experience taking production test systems from concept through FAT/SAT, launch, and rate production.
• Experience implementing production PCB flashing and configuration for embedded electronics, including firmware image control and programming verification.
• Proficiency in Python, LabVIEW/TestStand, or C#.
• 3D CAD experience for fixture and test interface design (Siemens NX preferred).
• Strong understanding of test strategy, test coverage, limit setting, MSA/Gage R&R, and statistical data analysis.
• Experience with structured problem-solving (8D, 5-Why, fishbone, fault tree analysis).
• Experience writing equipment specifications and managing external vendors.

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.
• Own the PCB flashing strategy. Decide where in the build flow boards and modules get programmed, and select programming methods and equipment 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.
• 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, 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, FAT, SAT, installation, and commissioning.
• Validate test systems before release using MSA/Gage R&R, golden-unit and limit-sample correlation, and guardband analysis.
• Run DOEs to optimize test methods, improve detection sensitivity, and reduce cycle time.
• Drive test readiness for new product introductions, design changes, and line bring-ups, including validation plans, cutover plans, and issue containment.
• Improve the failure feedback loop: fault isolation, diagnostic coverage, troubleshooting guides, retest logic, and fast feedback to design, suppliers, and process owners.
• Define test and programming requirements for suppliers and support customer and government acceptance activities, including ATPS and first article testing.
• Act as technical lead on test projects. Guide and review the work of engineers, technicians, and integrators, and mentor junior engineers.
• Support operations with training, documentation, and work instructions, and be the first responder to test station and test failure issues on the floor.
