This is a hands-on technical leadership role for an experienced troubleshooter who can diagnose analog, digital, DSP, and networked audio systems to the component level while maintaining reliable amplifier production output. The successful candidate will be accountable for amplifier assembly output, correct firmware loading, repair turnaround, first-pass yield, repeat-failure reduction, accurate production and service records, effective procedures, and the readiness of the amplifier assembly and repair function. The role is expected to spend approximately 75% of its time performing hands-on repair, troubleshooting, testing, and root cause work, and 25% managing amplifier assembly and firmware-loading workflow, reporting results, maintaining procedures, and developing personnel.Core ResponsibilitiesAmplifier Assembly & Firmware Loading: Own the day-to-day assembly, configuration, firmware loading, testing, and completion of amplifier products. Establish priorities, coordinate work, verify that the correct firmware and configuration are applied, maintain accurate output records, and address blockers that threaten schedule or quality.Aftermarket Electronics Repair: Own every assigned amplifier and electronics RMA or service repair from receipt and diagnosis through repair, verification, documentation, and return. Make and document the repair/replace/scrap decision within established authority. Production Test Repair: Own diagnosis and repair of amplifier and electronic units that fail production tests. Restore units efficiently, document findings, and use failure data to reduce recurring defects and test escapes.
