Senior Hardware Design Engineer – Digital & Wireless Systems

Apply Description Davenport/Quad Cities, Iowa or Remote $120,000–$150,000 Base Salary + Profit Sharing Approximately 10–15% Travel to Davenport, Iowa Grace Technologies is looking for a Senior Hardware Design Engineer to lead the digital side of our hardware development and help shape the next generation of connected industrial products. Grace is a global leader in electrical safety and predictive maintenance , with products protecting people and equipment in more than 60 countries. Our portfolio includes GracePort® panel interface connectors, Permanent Electrical Safety Devices (PESDs), GraceSense™ predictive maintenance technology, and Proxxi wearable safety technology. This is a hands-on senior engineering role spanning digital electronics, high-speed communications, embedded hardware, multilayer PCB design, and wireless connectivity. You'll work directly with analog, firmware, mechanical/electromechanical, product, and manufacturing engineering—and have meaningful influence over both individual products and our broader hardware architecture. What You'll Do Design digital and mixed-signal electronics , including microcontroller-based systems, data processing, communications, and connectivity. Lead hardware development for high-speed wired and wireless communication systems . Advance our capabilities in Wi-Fi, Bluetooth, cellular, and other wireless technologies , including RF design considerations. Own schematic capture, component selection, BOM development, PCB placement, routing, and design release. Design multilayer PCBs with attention to signal integrity, power integrity, grounding, EMI/EMC, and reliable communications . Work with interfaces and protocols including Ethernet, USB, CAN, RS-485, SPI, I2C, and UART . Prototype, bring up, test, debug, and validate hardware in the lab. Take designs from concept through prototype, certification, production, and field deployment . Work directly with board houses, contract manufacturers, suppliers, and certification labs. Support UL, CE, FCC, EMC , and other applicable regulatory requirements. Participate in design reviews, influence hardware architecture, introduce new technologies, and help develop less-experienced engineers. What We're Looking For Bachelor's degree in Electrical Engineering, Computer Engineering, or a related discipline , or equivalent relevant engineering experience. Extensive hands-on electronics hardware development experience, typically gained through approximately 10+ years of relevant professional experience , or equivalent senior-level capability. Deep experience with digital and mixed-signal, microcontroller-based hardware . Strong high-speed digital and communications hardware experience. Professional-level schematic capture and multilayer PCB design experience using Altium Designer or a comparable ECAD platform . Strong knowledge of signal integrity, power integrity, grounding, EMI/EMC, and PCB design practices . Experience taking multiple hardware products from concept through prototype, validation, certification, and volume manufacturing . Strong hands-on lab and hardware debugging skills. Especially Valuable Experience Experience with wireless/connected products, Industrial IoT, Wi-Fi, Bluetooth, cellular communications, RF/antenna considerations, industrial automation, sensors, field instrumentation, or ruggedized electronics is particularly valuable. Experience designing electronics for industrial, automotive, aerospace, defense, agriculture, food and beverage, or similarly demanding environments is also a plus. Why Grace? You won't be joining a large engineering organization where your responsibility stops when the schematic is finished. You'll follow your designs into the lab, through certification, onto the manufacturing floor, and ultimately into the field. As connectivity becomes increasingly important to our products, you'll have the opportunity to help determine how we build it—not simply execute someone else's design. If you want to stay hands-on technically while having real ownership over products and architecture, this role offers that opportunity. Location & Compensation This position may be based in Davenport, Iowa / the Quad Cities or worked remotely from an approved U.S. location. Remote employees should expect approximately 10–15% travel to Davenport for product development, hardware bring-up, testing, and design collaboration. The anticipated base salary range is $120,000–$150,000 , based on experience and technical background.
