Linux & Electronic Systems Technician

Linux & Electronic Systems Technician Location: Wayne, NJ Company: Inex Technologies Employment Type: Full-time, On-Site Compensation: $50,000–$70,000 per year, based on experience About the Role Inex Technologies is seeking a hands-on Linux & Electronic Systems Technician to configure, test, troubleshoot, repair, and support our intelligent vehicle-imaging and edge-computing systems. This role is intended for someone with practical experience working with embedded Linux devices, electronic hardware, IP networking, storage media, firmware, cameras, sensors, and related edge-computing equipment. Prior experience with license plate recognition or camera systems is helpful but not required. The successful candidate must be comfortable working directly from the Linux command line and diagnosing issues that cross hardware and software boundaries. This includes determining whether a device failure is related to the operating system, boot process, embedded storage, firmware, network configuration, power delivery, thermal conditions, cabling, electronics, camera settings, optics, environmental exposure, or another physical component. This is not primarily a software-development or electrical-design position. It is a practical technical role focused on: Embedded Linux provisioning, imaging, configuration, and recovery Device-level diagnostics and root-cause troubleshooting Electronics testing and repair IP networking and video-system configuration Production testing and quality control RMA evaluation and failure analysis Customer and field technical support Technical documentation and process improvement The right candidate will be curious about why a system failed—not simply how to reset, reimage, or replace it—and will be comfortable owning technical issues through resolution or appropriate escalation.
