Embedded Hardware Engineer

Please, no third parties. Permanent residents only. This is primarily an onsite position in Durham, NC, and no relocation assistance is available. Main Duties & Responsibilities: - Design and deliver embedded electronic hardware used within industrial sensor platforms, supporting the full lifecycle from early concept development through production readiness. - Create and maintain detailed schematics, select appropriate components, and develop PCB layouts for compact embedded boards while accounting for signal integrity, power efficiency, and manufacturing feasibility. - Engineer and validate designs utilizing embedded processors such as the ESP32 family, along with supporting components including ADCs, power regulation circuits, battery management systems, and peripheral interfaces. - Build prototypes and perform validation testing using laboratory instrumentation, in-system diagnostics, and iterative debugging techniques. - Work closely with firmware developers to integrate hardware with multiple firmware branches, enabling new features and diagnosing system-level behavior. - Develop targeted firmware utilities for diagnostics and validation—such as logging hooks, input validation routines, and test utilities—to accelerate hardware bring-up and troubleshooting. - Partner with internal test, manufacturing, and field teams to refine product designs based on operational data, reliability findings, and customer deployment feedback. - Assist with production readiness and ongoing sustaining engineering activities as devices transition into higher-volume manufacturing. - Contribute to continuous improvements of deployed hardware through structured troubleshooting and root-cause analysis. Skills & Requirements: - Bachelors degree in Electrical Engineering or a related field is highly preferred. - Hands-on experience designing embedded electronics built around ESP32-class microcontrollers or comparable embedded processors. - Practical background in power system design, including battery-powered electronics, charging circuits, and power management architectures. - Experience producing PCB schematics and layouts for dense, small-footprint circuit boards. - Solid understanding of mixed-signal electronics, including analog-to-digital conversion and signal conditioning techniques. - Familiarity with board-level communication interfaces and serial protocols such as SPI, I²C, UART, and CAN. - Ability to troubleshoot hardware/firmware interaction issues using tools such as oscilloscopes, logic analyzers, and embedded diagnostic code. - Strong analytical thinking and structured debugging approach when addressing complex system issues. - Effective communicator who can collaborate across firmware, hardware, testing, and manufacturing disciplines. - Detail-oriented with a focus on building reliable, production-ready electronics. Preferred Skills: - Experience supporting hardware products through manufacturing ramp and field deployment. - Exposure to industrial sensor platforms or ruggedized embedded systems used in demanding environments. - Experience writing or contributing to embedded firmware, particularly for diagnostic or validation purposes. - Familiarity with additional or custom microcontroller architectures beyond ESP32. - Awareness of EMI/EMC considerations when designing electronics intended for industrial environments. tags: senior embedded engineer, senior embedded systems engineer, senior embedded systems hardware engineer, senior electronics engineer, senior electronic engineer, senior mechanical engineer
