Xonar

At Xonar, Alex worked as a hardware and systems engineer, bridging embedded electronics, Linux infrastructure, and regulatory compliance across a range of products — including cabinet X-ray and radar-based weapons detections systems. His role spanned a wide range of engineering disciplines including customer-facing technical demonstrations and documentation.

Key Contributions

• Directed hardware design and system integration for embedded platforms, including GPU-based processing, microcontroller subsystems, LED assemblies, and serial communication upgrades for metal detection boards.
• Designed and deployed Linux-based infrastructure supporting data center configuration, multi-camera systems, kiosk environments, and training and display installations.
• Led hardware and software troubleshooting, repair, and continuous improvement efforts for deployed systems across multiple customer sites, improving reliability and field performance.
• Managed regulatory compliance and certification efforts for IEC/UL/EN-61010 and FCC/CE, coordinating with external test labs (Nemko) and ensuring documentation and labeling met international standards.
• Oversaw factory inspections, production readiness, and internal inventory management processes to maintain quality control and traceability.
• Supported pre- and post-sales engineering activities by scoping customer requirements, configuring hardware and software solutions, and resolving technical field issues.
• Delivered technical demonstrations and presentations of cabinet X-ray and radar-based systems, translating complex engineering concepts into clear customer-facing value.
• Created training materials, technical videos, and user documentation to support product launches, deployment, and onboarding.
