Design the Hardware Behind Life-Safety and Security Products At Radionix , we create products that protect people, property, and businesses around the world. Our engineers develop intrusion detection systems, wireless sensors, control panels, communicators, and connected security products that are installed in millions of locations globally. We are looking for a Senior PCB Design Engineer to join our product development team in Fairport, NY. In this role, you will work alongside hardware, firmware, RF, and mechanical engineers to transform ideas into manufacturable products. You will have a direct impact on products that move from concept through production and into the hands of customers worldwide. If you enjoy solving complex layout challenges, optimizing designs for performance and manufacturability, and working on products that ship, we want to hear from you. What You'll Do Design PCB layouts for digital, mixed-signal, power, RF, and wireless products from concept through production Collaborate closely with hardware, firmware, RF, and mechanical engineers to meet design and performance requirements Create and maintain schematics, symbols, footprints, and component libraries Define PCB stack-ups and support controlled impedance, differential pair routing, DDR signaling, and signal integrity requirements Perform or support signal integrity analysis of critical interfaces Partner with PCB fabricators and assembly suppliers during prototype and production builds Review designs for manufacturability, testability, reliability, and cost optimization Support EMC and regulatory compliance through best-practice PCB design techniques Resolve technical issues related to PCB fabrication and assembly Contribute to PCB design standards, libraries, and engineering process improvements Collaborate with global engineering teams to share best practices and support new product development initiatives Technologies You'll Work With High-speed digital interfaces RF technologies including Zigbee and LoRa Mixed-signal and power electronics Controlled impedance and differential pair routing Signal integrity analysis Multi-layer PCB design (2, 4, 6+ layers) EMC and regulatory compliance-focused design
